From:    Erinn Looney-Triggs 
Subject: Re: message on russter2...

Near as I can tell a user trahan logged in and then attempted to suspend the system.
Looks like she did that multiple times actually. This is probably the root cause of
this suspending and resuming the system can lead to a lot of funky errors and this
probably broke the serial connection.

Anyway, we should probably reboot the system if someone is up there to watch it and
that 'should' fix the issue.

Hi UnixOPS,

a message just appeared on my xterm window from russter2:

 Broadcast message from root (Mon Jul 20 12:31:45 2009):
 Warning communications lost with UPS UPS_IDEN

seems like it's related to the UPS software....any idea if this is
something to worry about?  i think the UPS is connected by a serial
cable to russter2....

thanks,

                                        SpB.

* Installed the OSU AmeriFlux KZ PAR-Lite sensor at the top of the
tower (note it is at an angle to the sun, same as it was left last
year).  Just like last year, it's, "PAR2.up".  Brought the box back to
campus.

The new calibration coefficient is:

Subject: Re: ADAMs


Hi,

i have some other things to take care of...here's a quick summary of
what i did:

1. arrived, network was not working.  port4 where the fiber optic
cable connects to the fiber-to-copper converter in the quacker box was
not lighting up.  I moved the fiber pair to port3 and then the lights
came on.  And i was able to get on the internet at the tram location.

2. i've rebooted the adam by turning the power switch on the outside
of the box on/off a few times now.  still can't ping isffa from
russter2.  lights are on in the viper so i know there is power
there...also the usb drive is lit up.  the network cable that goes to
the adam (ie, connected to the hub in the red tub) has two
lights---the green "lnk/act" light is rapidly flashing on/off...the
"100M" light is solid orange.  this cable connects to "eth1" on the
side of the adam...i would try a different network cable, but it needs
a special connector (though i do see some normal rj-45 connectors
inside the adam box)...

i'll check my email again before i leave, but i have some other
work to do...

thanks,

                                SpB.

Hi Betsy,

I was finally able to check the serial numbers of the short-haul
modems that are out in the field...one is a ME721A rather than a
ME800A, they are:

 Model      Serial Number    Logger
------      -------------   --------
ME800A-R2   sn 0202          UCB (logger end)
ME721A-M    717N0056         UC (logger end)

ME800A-R3   sn 0605          UCB (tower end)
ME800A-R3   sn 0405          UC (tower end)

If we can't add the ME721A to the "double diamond" protection plan,
then just do the three ME800A's....

If you need other information or have any other question let me
know...and please let me know what type of document i get that shows
the protection plan, etc...my understanding is that it is $17/unit for
three years of protection, correct?

thanks,

                                        SpB.

Purpose of visit: fix data system from lightning strike on Monday.

Weather: Forecast was 40-50% chance of rain.  Never happened except
for a few small ice pellets.  It was socked in down on the plains at
mid-day.

--------- Misc Notes:

* drove up CU gray Jeep.

* not much snow left.

* Lynette + PAR crew was working at grove 1.

* Bob from UCAR safety was up visiting.

* the Aspens are leafing out...

---------

* span pressure = 250 psi; N2 pressure 705 psi.

* at ~9:30 MST, swapped out Edgeport/8, data system back up (note,
left channels 200 & 202 off system). And replaced short-haul for UC
logger.

* New Edgeport (from ebay):  PN (1P) 50001231-01, SN (S) V22116393

* to connect the ATI/ati sonic:  no null modem, 9600 baud, 8-N-1.

* based on the weather forecast, turned off the LI-6262 box fan.

* shut-off both the mrs cr10 and noahs snow depth logger.

* downloaded logger data (hit all loggers, reset the times on all
loggers):

Purpose of visit: fix fast cr23x data logger

Weather: It started snowing (ice pellets) when i arrived.  There were
some very big clouds around (mostly to the east).  It was a bit windy
at times, but also sunny and nice other times.  There was only one
distant rumble of thunder...as i left the clouds completely cleared
off.  And it was clear skies and sunny...

--------- Misc Notes:

* drove up CU gray Jeep.

* still a few piles of snow "holding on".  Added a bit of salt to the
ground rod (plenty of water in there)...

* the Aspens are really leafing out...almost fully out.

---------

* span pressure = ? psi; N2 pressure ? psi.

* on sunday morning (7 June) i noticed the file sizes changed
  dramatically on the 6th, ie:

-r--r--r-- 1 root  aster 39049534 Jun  6 10:00 nwt090606.080000
-r--r--r-- 1 root  aster 39049502 Jun  6 18:00 nwt090606.160000

-r--r--r-- 1 root  aster 34115462 Jun  7 18:00 nwt090607.160000

* it looks like at around 17:20 MST the fast logger (chan 201) stopped
spitting out data...ie:

data_stats < /data/projects/NIWOT/raw_data/all/nwt090607.000000
Opened:

* after connecting to the "fast" cr23x logger the time seemed fine,
but when i tried to look at the data the numbers were not changing...i
tried re-sending the program (fast_07.csi), but this did not fix the
problem.  All the values then went to zero.  This indicated a problem
with the logger (and not somewhere downstream of the logger).  My
suspicion was that it was related to the internal batteries...which I
happened to have two spares of....swapped out the batteries and then
it worked ok.  The logger was fixed at aruond 11:27 MST, ie:

-------------------------------
At the site: SpB, LL, SL, LY

Purpose of visit: change LI-6262 Nupro filters/work on PAR.

Weather: Mostly clear up in the mountains.  Not too windy.  Could see
a heavy cloud layer down on the plains from the tower.  Clouded up a
bit in the afternoon.

--------- Misc Notes:

* drove up CU gray Jeep.

* still piles of snow "holding on".  But things are really starting to
open up now.

* the Aspens are leafing out...my camera ran out of battery juice, so
no photos of them!

---------

* span pressure = 300 psi; N2 pressure 900 psi.

* turned on fans in both the LI-6251 and LI-6262 boxes.

* at 11:00 MST, disconnected LI-6262 from side of box.

  - between 11:00-11:26 MST, replaced 2-micron filters both
    at the inlet and inside the LI-6262 box.

* rest of the day was spent helping with the installation of PAR.

Purpose of visit: replace batteries.

Weather:  Drizzly rain when we arrived.  This turned into a steady
rain by the time we left.

--------- Misc Notes:

* drove up CU gray Jeep.

* Chris gray and his helper (Alyssa) were up there looking for a spot
to setup the PTR-MS and they also grabbed a few sampling chambers...

* there is still snow left, but you can get to the tower without walking
in it.  lots of water on the trail (it's been raining a lot).

* the Aspens are just starting to leaf out...

---------

* span pressure = 400 psi; N2 pressure 1080 psi.

* on Sunday night I noticed the tower data had stopped being
archived...when trying to reboot the quacker the edgeport was not
getting recognized...here's my email:

 Hi,

 fyi---it looks like the tower data system shut down this afternoon
 about 2:30pm.  And now the Edgeport is not getting recognized on
 reboot..i'm getting a message like:

 May 31 22:21:28 quacker kernel: hub.c: new USB device 00:07.2-1, assigned address 2

 May 31 22:21:28 quacker kernel: usb.c: USB device not accepting new address=3 (error=-110)

 and this is supposed to look like:

 based on the timing, i'm guessing the problem is probably due to
 lightning....I just added my name to the jeep calendar to go up
 tomorrow.  It says there were 4 people going up in the jeep tomorrow
 so I assume one more person is ok (if not please let me know ASAP).
 It also says that you are leaving from campus at 9am...so i'll plan to
 be on campus before 9am.

 Gordon, i still have your edgeport and i'll bring that with me for a
 swap out if that is needed...

 thanks,

                                        SpB.

 
* at 10:15 MST, power-cycled the 2-d ati sonic (i think the serial port
on the back of the quacker died)....

* swapped out edgeport/8's (now using Gordons/eol's).  Tower data back up
and running, ie:

-r--r--r-- 1 root  aster 39049448 May 31 10:00 nwt090531.080000

Purpose of visit: replace batteries.

Weather:  Perfect day to be working up at the site.  The bugs have
not arrived yet, and temps are cool and pleasant.

--------- Misc Notes:

* drove up CU gray Jeep.

* Lots of things happening at the site: Steve Oncley was working on
TRAM, Laura was showing plots to Loles/Chris, Lynette was moving stuff
around, Nicole had her whole crew with her...

* still a bit too snowy on the trail to use the cart.

---------

* span pressure = 400 psi; N2 pressure 1080 psi.

* visited the west robot (downloaded logger data and unplugged
everything in preparation for removal of the robot in June).

* replaced the battery on the Tripp-lite UPS backup power-strip (above
the LI-6262).  Note that getting this thing out of the box was rather
inconvenient...it has both velcro-type stuff and also two screws that
hold it in place.  To get it off the screws you need to slide it to
the right or left...i should have removed the velcro, but once i put
it back in place it was still very difficult to remove so i just left
it as-is.

* from approx 12:55-12:57 MST, checked flows/pressure in LI-6262:

              flow             Pressure
sample        8.52              50.39
span          8.33              49.50
span          8.52              50.56  (after needle valve adj)

* swapped profilter dessicant...details:

* from 13:00 - 13:19 MST, swapped out the dessicant on the profiler (li-6251).
    - at 13:04 MST, did zero (value is approx 0.006 mV).
    - at 13:16 MST,  did zero + blow test (ok).
                (zero is approx 0.000 mV).
    - at 13:19 MST,  back to auto mode.  flow rate at ~14.

* plugged russter2 directly into the UPS and this seemed to fix the
rebooting "problem"??  Note, you cannot "daisy-chain" two UPSs
together to get twice the amount of time after an outage.  BOTH
batteries will kick on at the same time...

Weather: Bright and sunny.  About 3 FEET of fresh snow.  The snow was
dripping and sloughing off the trees.  Very wet and heavy.  It was
mostly calm, with a few bursts of wind every now and then.  A few
clouds showed up in the afternoon...and there was a cloud up near the
divide...the temperature was well above freezing...

--------- Misc Notes:

* drove up my Jeep.  First one to drive to MRS (which took a bit of
speed and power).  It looked like the road to MRS was last plowed on
Friday?  (or maybe sometime on Saturday).

* Kurt and Isabelle showed up and drove the snowcat up to cable gate
(and picked me up as I was trying to break trail along the road).

* it took me over an hour to get from the trailer to the tower....

---------

* snow depths:

              closest to tree = covered.
       TP101 461 middle probe = could not read, above highest mark (see photo)
               farthest probe = could not read, above highest mark (see photo)

* span pressure = 600 psi;

* from 14:00-16:00 MST, switched N2 cylinder at the tower (new
  cylinder=CC198519 (1900 psi); old cylinder=CC264970 (0 psi)).  Note,
  left old cylinder at the tower...also, CC198519 was missing the
  valve, so removed the one from CC264970 and used that.

* on Friday I changed the forestcam photo rate from every 2 hours to
every 10 minutes...this is a good thing to do when/if there are

Hi,

i'm sure most of you are well aware of this...some more details and
predictions for the storm are listed below....could this have some
potential for the record-setting snowfall in April 1921 (when 87" fell
in just over 24 hours!!)??...ie:

 http://ams.allenpress.com/perlserv/?request=get-abstract&doi=10.1175%2F1520-0493\
(1953)081<0038%3ARSOAAS>2.0.CO%3B2

the timing seems about right...


                                SpB.

Subject: Thursday MoCast:   Monumental Spring Storm!!!


Here is your MoCast update for Thursday, April 16, at 10:00 am

Monumental Spring Storm taking shape!!!!!!

The latest numerical guidance is all consistent in producing strong,
deep upslope across eastern Colorado and the Front Range mountains for
the next 60 hrs., with total precipitation likely reaching 3 to 5
inches (melted) by late Saturday.  The big question still is whether
surface temperatures will support deep snow accumulations at lower
elevations (e.g., downtown Boulder, Denver, etc.), but the current
guidance suggests it will be just cold enough.....

One aspect that seems quite certain is that the foothills above 7000
ft will likely see 24 to 48 inches of snow by Saturday, with some
areas possibly receiving 60 inches!!!  Roads may become impassable by
Friday morning, remaining such possibly till Sunday.

So, first, for the lower elevations (e.g., below 7000 ft), rain with
embedded thunderstorms is likely Thursday afternoon, turning to heavy
wet snow Thursday evening, and continuing, heavy at times, through
Saturday. The snow may mix at times with rain Friday, but will likely
turn back to all snow Friday night and Saturday.

Best guess at snow accumulations by Saturday:

 .....below 6000 ft  (e.g., Boulder, Denver, Longmont, etc.)   8 - 16 inches  (mo\
stly on the grass)

 .....6000 to 7000 ft     14 - 28  inches

For higher elevations (e.g., above 7000 ft), snow today, becoming
heavy Thursday night, and continuing heavy at times through Saturday.
Roads may become impassable by Friday morning, remaining such till
Sunday.

Best guess at snow accumulations by Saturday: 24 - 48 inches, with
some local areas reaching up to 60 inches!!

   happy spring!!!!

      Morris

At the site: SpB

Purpose of visit: reboot russter2.

Weather: Clear and sunny.  It was a bit gusty, but I did manage to get
up to the top of the tower and grab CNR logger data.  The snowpack is
hurting.

--------- Misc Notes:

* drove up my own Jeep.

* missed the wed lab meeting....

---------

* snow depths:

              closest to tree = 56 cm

               farthest probe = 75 cm

* span pressure = 1000 psi; N2 = 1150 psi.

* on the afternoon of Mar 10 there was a power outage...the power went
off at around noon, and the data system appears to have shutdown at
13:59 (which gives a rough estimate of how long the batteries will
keep things going).

* just before I was getting ready to leave i noticed the LI-6262 data
were way off on cockpit...SO, i made another trip out to the tower.
It turns out that the power for the LI-6262 is in a small grey box
just above the LI-6262 box...and the power is connected to a "Internet
Office 280, Tripp Lite Power Protection" power strip.  (basically, a
power strip with a small battery in it).  This battery must be dead.
So, I moved the power coord to the "surge-protected only" side of the
power strip...and then the LI-6262 started working again.

               farthest probe = 72 cm

* span pressure = 1210 psi; N2 = 1850 psi.

* dragged a span cylinder from the front of the trailer out to the
  tower (cc153480).  Placed this next to the one currently running at
  the tower (both are under the blue tarp).

* from around 11:50-13:18 MST, swapped N2 at the tower.  (did leak
  check during that time).  (new cylinder=CC264970 (1850 psi); old
  cylinder=CC176242 (approx 0 psi)).  Dragged CC176242 back to C1 and
  put it in front of the trailer.  Tried to position my old shower
  curtain over the N2 cylinder to try and keep the snow off the
  regulator...

* at around 12:00 MST, adjusted the flow rates for the LI-6262:

                pressure    flow rate
   sample         52.07      9.09
       N2         51.59      9.02
     span         53.70      9.53

i used the needle valve in the li-6262 box to lower the flow rate of
both span and N2 (to make the span agree better, don't care as much
about N2).

* Checked on the rig for the REBS sensor at the top of the tower...my
kluge seemed to hold up during the strong winds of last week...might
need to get a turnbuckle at some point (or just leave as-is?).

* downloaded logger data:

Friday, January 30th, 2009 Visit:
---------------------------------
At the site: SpB

Purpose of visit: Check on MET logger.

Weather: A bit blustery, but air temp was above freezing.  Lots
of new snow in the trees from last time I was at the site.  When
i was off-trail the snow was approx knee-deep.

--------- Misc Notes:

* drove up a CU prius.

* Dean Anderson (USGS) was kind enough to let me borrow a cr23x in
case I needed to swap out the MET logger.

* Can still walk up the power line without the need for skiis or
snowshoes.

---------

* pulled a pine needle out of the rain gauge.

* snow depths:

              closest to tree = 54 cm
       TP101 461 middle probe = 71 cm
               farthest probe = 73 cm

* moved power for MET logger to 12 V power supply which is being used
for the NCTC logger.  MET logger up and running again at 13:42 MST.

Note:  red wire = +12V,  green wire = ground.


* note, met logger (chan 204) died on 1/25:

Subject: CR23X

Mr. Burns:
     You can reset the CR23X, as you stated in the *A Mode and the 5th
window type 98765 and hit the A key. It will take about 15 minutes to
reset, so walk away for a time. You can go on our web page and get the
latest operating system for the CR23X if you don't have it all
ready. OS 19 is the latest version. Use Device Configuration Utility
to down load the OS. If I can be of any assistance please contact me.

---------------------------

* N2 cylinder at tower at 400 psi.

* hauled N2 cylinder CC264970 from trailer front to tower.

* from 15:00-15:50 MST, switched span gas at the tower (new
  cylinder=SG9151924 (1400 psi); old cylinder=CC282376 (approx 100
  psi)).  Note that SG9151924 was originally going to be used at
  the east robot.

* from 15:24 - 15:44 MST, swapped out the dessicant on the profiler (li-6251).
    - at 15:24 MST, did zero (value is approx 0.001 mV).
    - at 15:42,  did zero + blow test (ok).
                (zero is approx -0.003 mV, span could not do since swapping cylinder).
    - at 15:44,  back to auto mode.  flow rate at ~13.

NOTE: need to re-do the swagelock fittings...the fitting one one side
is trashing the threads on the dessicant tube.  Need to REPLACE!!

* on 2/4/09 updated the programs:

-rwxrwxr-x   1 sburns      19464 Feb  4 11:28 cal.co2.q*
-rwxrwxr-x   1 sburns      15682 Feb  4 11:31 cal.prof.q*

 Cspan <- 408.13        #  cal cylinder is Airgas SG9151924BAL calib on 080515:
                        #  (408.42+407.7+408.27)./3 = 408.13 ppm
                        #  Airgas value:  401.8 ppm
                        }

Wednesday, January 21st, 2009 Visit:
------------------------------------
At the site: SpB, NT, SL

Purpose of visit: Download logger data.

Weather: Almost, HOT.  Unseasonably warm air temps.  Clear blue skies.
As we were leaving a few high cirrus clouds were starting to form.
Some gusts of wind from the south, but generally pleasant.  Down in
Boulder it was in the 70s F.


--------- Misc Notes:

* drove up a CU prius.

* Nicole/Stan were collecting sub-surface air samples.

* moose tracks (and scat) all over the place near como creek crossing.

* a lot of the exposed areas are snow-free.  Walk up the power line
was half on dirt half on snow.

---------

* snow depths:

              closest to tree = 37 cm
       TP101 461 middle probe = 50 cm
               farthest probe = 32 cm

* gas cylinder pressures:  N2= 700 psi, span= 320 psi.

* confirmed that there is an extra dessicant tube in the bowling shed.

* noticed that the cable for the REB Rnet logger had come loose...need
a new turnbuckle.  probably need to re-do the way these booms are held
in place...

* downloaded logger data and reset cr23x clocks (no time problems, all
  were within 30 seconds).  files:

Friday, January 16th, 2009 Visit:
---------------------------------
At the site: SpB

Purpose of visit: Travel to T-van for AIRCOA service.  Go
to tower to download logger data (if time).

Weather: Clear and sunny and warm.  Wind picked up as the day went on,
but a very nice day from mid-January.  Snow warmed up during the day.
There was an ice-crust coming down.

--------- Misc Notes:

* borrowed an EOL jeep liberty for the trip up.

* Andy Watt gave me the replacement micropump, crimper, + some
backup pins.  Grabbed podocarp from the trailer + misc tools.

* carried ski's up to C1 and then skied from there.  Snow coverage
above C1 was good, but there were a few bare spots.  The trip from C1
to T-van took a bit over 2.5 hours.  Coming down took about 1:15.

---------

* arrived at the site at around 13:00 MST.  Connected to AIRCOA-A via
  a serial cable.  Notes on the connection:

  - There is a separate network cable that goes from the AIRCOA to the
    network.  To connect to the AIRCOA with the serial cable (via port
    2), a null modem is needed.

  - Using hyperterm the settings need to be:

  - from the hyperterm window it was possible to log into external
    computers via ssh.  BUT, need IP addresses.
    Note: gate.ucar.edu = 192.43.244.60

* confirmed that the purple "flywheel" on the micropump was not
  turning.

* started the rrelay software with "./rr_job".  Note, at first this
  did not work because the aircoa software was not running (duh).  So,
  re-activate the aircoa program by:


* did a reboot to make sure everything re-started cleanly.

* after confirming the sample flow rate was zero (ie, sample voltage
  output is approx 1.0 V), did a "high-pressure" leak check with the
  current pump in place.  It worked out to be around

the divide at various locations throughout the day.  Blowing
snow up at the divide.  At times clear and sunny.  At times
calm.

--------- Misc Notes:

* drove up a CU prius.

* Happy New Year!

* a lot of the exposed areas are snow-free.  Walk up the power line
was half on dirt half on wind-crusted snow.  there was a layer of
needles/twigs just below the upper snow surface.

Wednesday, December 17th, 2008 Visit:
-------------------------------------
At the site: SpB

Purpose of visit: To swap out the N2 cylinder and download
some logger data.

Weather: a bit on the chilly side, but the winds were reasonable.
Some strong downslope gusts from time-to-time.  Still some fresh
snow in the trees that was blowing around at times....

--------- Misc Notes:

* drove up a CU prius.

* snow is about mid-shin and fluffy.

---------

* snow depths:

              closest to tree = 25 cm
       TP101 461 middle probe = 36 cm
               farthest probe = 35 cm

* swapped N2 cylinder.  Old cylinder CC262287 at approx 0 psi.
                        New cylinder CC176242 at 1800 psi.

leak check from around 1:30-2:30pm...it didn't hold quite as well as i
would have liked.  initially there seemed to be a "major" leak...i
tried using snoop, but that does not work very well when it's so
cold...after using the snoop (could not find a problem) and re-doing
the fitting the leak seemed to go away ??.  i wondered if the leak was
not at the main connection to the cylinder...

* downloaded logger data (no time problems, updated the times on all
loggers; synched to russter2 time.  NCTC was off by approx 2 minutes,
slow):

Hi Jeff,

thanks for taking care of the forestcam photos.  you'll have to show
me the program and also how you are archiving these data....or send me
an email with this info would be fine too.

i've been looking at the recent logger data...and it appears that
there is a large time gap in the "soil11_12.dat" file....ie, if you
look on russter2 at the file:

Note that on day 309 (Tuesday 4 Nov) at 1440 there is a large gap in
the data...and/or the time jumps.  From the calendar it looks like no
one was up at the site that day...Did you happen to check that the
time/date is ok when you downloaded the data on Nov 12th (or on Nov
20th)?  Was there anything strange that happened with the download on
Nov 12th?  Based on the last row in the soil11_12.dat datafile you
should have downloaded these data on 12 Nov at around 14:20 MST.  Does
that sound approx correct?

the battery voltage for the soil logger looks ok, but this could also
be a warning sign that the soil logger battery is starting to have
problems...

Noah, i'm cc'ing you since it sounds like you are at the site on Tue
Nov 11th (day 316).  Can you confirm which days you were up at the
site so I can add this info to the calendar...also, a brief summary of
what you did would be nice so we can add this info to the logbook.

jeff, how did the map turn out?  i'm planning to stop by tomorrow
morning and we can take a look at this if you are going to be
around...

thanks,

                                        SpB.

Hi Sean.

I noticed this gap in the soil data when I was downloading the file on
11/12...Sorry about forgetting to mention this to you. Not sure what
to say about it. Nothing out of the ordinary happened and the
time/date looked fine on 11/12 and 11/20. And yes, you are correct
that I downloaded these data in the afternoon of 11/12, and I remember
checking on the "monitor" screen that the time of the last row in the
data file matched the time the file finished downloading.

I'll come by tomorrow too and we can look at the GPS data some more
and I'll give you the run down of how I process and archive the
forestcam photos.

Jeff

Site trip on Monday, November 3, 2008
-------------------------------------------------------------------------------
At the site: Jeff, Nicole

Weather: decent day, a little chilly but mostly sunny
-------------------------------------------------------------------------------

* N2 @ 1450, span @ 1075

* grabbed soil and tcs data

* tried new snow temp probe with a terminal strip connection instead of the 
  amp connector (see details): there seems to be a problem with getting enough
  power through the smaller wires of the extension to the larger wires of 
  the probe, i.e. when everything was connected the probe worked only 
  intermittently

* got some GPS data around the tower (see details): borrowed the new Trimble 
  GPS from LTER and brought it out to the tower for the day. Got four corner
  points for each of the towers (main, canopy, north canopy); got several spots
  along the trail between the main tower and the north canopy tower, including
  one spot that is adjacent to the soil logger; got a point for each of the 
  sonic snow depth sensors. 

  Note: the GPS was not working too well today. It only worked in mid-afternoon.
  There is a desktop computer (from Todd Ackerman) in the LTER lab that should
  be used for downloading data from the new Trimble unit.

* brought the suitcase that was in the shed out to the robot

Site trip on Friday, October 31, 2008
-------------------------------------------------------------------------------
At the site: Jeff, Sean

Weather: exceptional day; warm and calm
-------------------------------------------------------------------------------

* brought up a new N2 tank from Ramaley, cc264970

* from 10:30-11:15 MST, removed csat 0438 at 21.5m, added csat 0328 at 21.5m 
  (w/ "rain" upgrade)

* at 14:30 MST, added csat 0438 at 5.7m

* at 14:30 MST, started ops49 (added a TC at 30cm AGL to UCB logger)

* at 14:30 MST, started running "ucb_10.csi" on UCB logger

Site trip on Thursday, October 30, 2008
-------------------------------------------------------------------------------
At the site: Jeff, Maggie, Nicole

Weather: very windy in the morning then calm after midday; warm throughout
-------------------------------------------------------------------------------

* did all of Maggie's new growth collections

* helped winterize NT's plots

* checked on tanks running at the tower, both okay

* brought up a new N2 tank from Ramaley, cc264964 

Site visit on Tuesday, October 28, 2008 
-------------------------------------------------------------------------------
At the site: Jeff, Maggie, Nicole, Sean

Weather: very warm, calm
-------------------------------------------------------------------------------

* N2 @ 1610, span @ 1150 

* cleaned the krypton

* transferred our last amp connector to the snow temp probe that is known to 
  be working; connected this probe to the mrs logger and sent mrs_03c.dld to the
  logger but the probe was not working; when we tested this probe during our
  last visit I wired the probe's leads directly into the logger; on this visit
  the probe was connected to the 75 foot extension I prepared for it...we
  checked the wires in the extension with the multimeter and found that two of
  the four wires have infinite resistance...something is wrong either with the
  cable itself or the connections at the amp connector pins...probably at the
  pins because the cable is new

Site trip on Sunday, October 19, 2008
-------------------------------------------------------------------------------
At the site: Jeff, Maggie, Sean, Nicole, Stan, and Maggie's two dogs, Flurry
and Harley.

Weather: a pretty nice day with temps in the upper 50s and clear skies in the
morning, a very brief snow flurry mid-afternoon

Misc: Flurry and Harley helped Maggie carrie stuff around the forest while she 
was taking dendrometer band measurements
-------------------------------------------------------------------------------

* Installed the new soil moisture sensors (cs-616s) and re-deployed some of 
  the cs-615 sensors in new locations so that each one is co-located with a 
  snow depth sensor (see details)...details are forthcoming 

* N2 cylinder was at approx 1830 psi (so leak is most likely in the N2 zero 
  cal of the LI-6262)

* made an amp connector extension with 75 ft. of cable for one of the new soil 
  temp sensors, but the sensor didn't seem to work...maybe not the same one 
  we tested at the mrs logger? We tested one new probe and it seemed to work. 
  I thought this probe was back in the shed but I couldn't find it there. We 
  had a different but similar probe out from the trailer but it didn't seem
  to work like the probe we previously tested. Need to figure out where the 
  first probe went...

Site trip Thursday, October 16, 2008
-------------------------------------------------------------------------------
At the site: Jeff, Sean, Lynette, Steve Oncley

Weather: cold and windy, still some snow on the ground around the tower

Misc. Steve Oncley ran tram for a few hours, about 20 non-consecutive laps 
around the track. 
-------------------------------------------------------------------------------

* brought up the last two cylinders from Ramaley, both span, CC153480 
  and CC245057

* N2 (CC125575) bled almost dry since Tuesday! a leak somewhere in the 
  system...retired this cylinder 

* see below for Sean's notes on the leak...

* started new N2 cylinder CC262287 at 1850 psi

* span @ 1250 psi 

* swapped the mag. perch. and indicator tube at the LI-6251 

* an e-mail from Sean to Andrew Turnipseed on Friday, 10/17/08:

  ...after taking a look in the LI-6262 box yesterday it looks like only one 
  of the two smaller parker valves on the left side of the box is actually 
  being used...I think this means we could replace the valve on the far 
  left side with an elbow and use that valve as a spare if we need to. I know 
  you are busy with lots of other things, but I wanted to give you a quick
  update about what happened yesterday and if you have any ideas/suggestions 
  I would be glad to hear them...unfortunately I forgot to bring your notebook 
  with all the diagrams (i'll try to remember to bring that next time i'm in 
  the trailer)...I think i was able to figure most of it out by looking
  at it...here are some details about what happened:

  1. when jeff went up on Tuesday the N2 calibrations "magically"
  started working again...the cals had been having problems for the past
  3-4 days where the flow rate would go way down during the N2 part of
  the cal.  the span part of the cal seemed to be ok.  the cal at 8 AM
  that morning had this same problem, but the one at noon was ok (which
  was before Jeff had done anything except go up the tower to download
  logger data).  After the noon calibration worked, jeff checked it
  manually at the box and it still worked fine.  The N2 cylinder was at
  700 psi on Tuesday.  I suspect when he walked up the tower it shook
  the box, so that some connection in the box moved and then it started
  working again....i don't have any other explaination for why it
  suddenly started working again...

  2. the cals appear to have kept on working fine since tuesday...but
  when we were at the site yesterday the N2 cylinder was near zero psi.
  (there was still 20 psi on the line side of the regulator).

  So it appears that we have a leak in the N2-part of the system
  somewhere...i have assumed this leak is not in the flow through the
  reference cells unless it is before (or at) the needle valve in the
  LI-6251 box....if there was a leak downstream of that needle valve
  then it would be the same as the normal flow that goes through those
  reference cells (plus the needle valve drops the pressure so most of
  those connections are at low pressure)...

  one other note that seems relevant/important: as i was tightening wa
  loose screw in the LI-6262 box i felt a buzz/burning in my hand...the
  entire back metal panel of that box is "hot".  So i suspect there is a
  short somewhere...this might explain part of what is going on.  We
  tested this by putting the multi-meter between the terminal strip (the
  one just to the left of the flow meter in the photo) and the back
  panel and it showed 120VAC.  testing the relays everything seemed to
  be ok (ie, the 120VAC would get passed through there as it should be)...

  in an effort to isolate the leak we left everything hooked up, but
  capped off the line before it went into the N2 line on the top of the
  LI-6262 box (see photo).  This was to check whether or not there was
  an internal leak or not in any of the fittings within the box....and
  it appears that N2 is typically within the line from the 2nd valve on
  the right up until the 2-way big blue galtek valve.  This is because
  the smaller parker valve is normally-open in this configuration. . .

  anyway, we are going to try and get the leak isolated and then we can
  better figure out what's going on from there...If we isolate the leak
  to somewhere inside the LI-6262 box and can't figure out where it is,
  we may pull the box and take it back to the trailer and then really
  start ripping it apart (depends on the weather)...i'll list a few more
  things we checked below...sorry for the long-winded email!


						SpB.




1. did a leak check on the tubing going from the N2 cylinder up to the
   boxes (capped the lines at the boxes).  This seemed ok, but maybe
   we did not let it sit long enough...at least there did not seem to
   be a major leak.

2. removed the dessicant/soda lime attached to the N2 regulator.

3. checked dekaron tubing running up the tower from the N2 for any
   obvious wear/cracks, etc...didn't notice anything obvious.

4. tried to snoop all the fittings with high-pressure N2. (didn't find
   anything obvious).

5. re-tightened all tees/fittings going from the N2 cylinder up to the
   LI-COR boxes.  Removed one extraneous tee for N2 that went into the
   LI-6262 box (I think this was probably a remanant of an old
   configuration of the system).  Rather than use this TEE/line ran
   the dekabon tubing directly in the fitting at the top of the box.

6. in an effort to isolate the problem we kept the system running with
   everything connected in the LI-6251 box, but with only the ref gas
   running through the LI-6262 box (capped the line going into the N2
   calibration).


* things left to do/check:

  1. replace all dekaron tubing.

  2. I have assumed that any leak behind the needle valve (in the
     LI-6251 box) would not bleed the N2 cylinder excessively (so do
     not need to worry about leaks downstream of this needle
     valve)....need to check the needle valve more carefullly...it's
     possible the leak could be at the needle valve or just before it.

  3. try to figure out why there is a short in the LI-6262 box.  Has
     it always been like this?

* 3-way Parker valve: 1-141-900, VAC 20 PSIG

* LI-6251 2-way valve, "General Valve Corp" 4-178-900, VAC 100 PSIG

Site visit on Tuesday, October 14, 2008
-------------------------------------------------------------------------------
At the site: Jeff, Nicole

Weather: cold, about 28F when we got up to the trailer, and sunny until midday
when the sky became very overcast, looked like it might snow but never did

Misc: still about 4 inches of snow on the ground around C1 and the tower from
Sunday's snow storm
-------------------------------------------------------------------------------

* brought up 1 new N2 cylinder and 1 new span cylinder to the trailer from 
  Ramaley

* swapped 15 flasks at the west robot then changed it to "winter mode" 
  (i.e. 4 flasks every two weeks)

   - to do this I did *0, *4A, AAAAAAAAA (nine more As), 1A (this combo 
     switches from 15 flasks to 4 flasks, with 0 for summer and 1 for winter
   - then I did *0, *4A, 14A, *0 (in this combo the 14 is for bi-weekly
     sampling instead of weekly sampling, and the *0 at the end enters both
     new entries...notice how there is no *0 at the end of the first entry)
   - BE CAREFUL not to hit *0 until after both entries are made because *0 
     updates the program on the logger (effectively power cycling the logger 
     just as if you pulled the green power plug)

* downloaded from soil, UC, UCB, nctc and prof 

* fired up the mrs logger and Noah's logger, sent mrs_03b.dld to the mrs logger

* span @ 1250 psi, N2 @ 700 psi

* from ~1:55-1:58 MDT did a manual N2 calibration of the EC system to test 
  the N2 flow rate

* about the solenoid valves in the LI-6262 box:
  - Of the three smaller valves, two are identical and one is unique. This 
    unique valve is the one that sits between the two big blue valves. This 
    unique valve comes from Parker, with part number 9-823-900, VAC-100 PSIG. 
    The two identical, slightly larger valves, which sit in the upper left 
    corner of the box share the same part number (obviously) but I could not 
    read all of it. What I could see was Parker, 4-209-???. These also have 
    specs of VAC-100 PSIG. The rest of the part number on these two valves was 
    wrapped around to the far side of the valve so I couldn't see all of it.

    As for the two blue valves, there is no brand name on them. One of these 
    valves has part number 203-3414-415 with VAC 115 and s/n 1508019. The 
    other has part number 203-1414-415 with VAC 115 and s/n 1501018. 

Site trip Thurs, Oct 9, 2008
--------------------------------------------------------------------------------
At the site: Jeff, Sean, Nicole, Maggie, Amy

Weather: Sunny and clear at the site (upslope winds). Socked in with clouds 
         down on the plains. nice, pretty calm and warm

Misc: Nicole drove up on her own and traded in the teal Jeep for the gray one
      later in the day
-------------------------------------------------------------------------------

* finished par wand removal at grove 3

* SpB connected all 8 new CS-616s to soil logger 416 mux, started IC 
 (see notes for details) 

* from 12:15-12:30 MST, removed 5.6m csat (sn 0328) from mini-tower 

* JB, MP and AW hauled most of the PAR equipment out of the forest and back to 
  CU (stored mostly in the "cool" room with the fridge)

  I think only one battery remains at the site, near grove 3

Site trip on Tues, Oct 7, 2008
--------------------------------------------------------------------------------
At the site: Jeff, Sean, Maggie, Nicole, Amy Watson

Weather: cooler, some wind (especially at the top of the ladder), and now most
of the aspen leaves around the site have fallen. 

Misc: 2 robot suitcases in the shed
--------------------------------------------------------------------------------
* swapped 15 flasks at the west robot

* finished par wand removal at grove 2

* SpB got 5 of the CS616s working and calibrating in some soil near the 
  soil logger

  -in the program he had to account for the addition of another mux, and I 
   think there was a grounding issue as well...Each probe has a ground wire and
   a shield wire that together go to a "shield" port on the mux, but it seems 
   that these shield ports also have to be physically grounded to the mux's 
   main GND port, which is located with the 12V, CLK and RES ports...so SpB 
   connected the shield port he used to the main GND port with some wire

Site visit on Friday, Oct 3, 2008
--------------------------------------------------------------------------------
At the site: Jeff, Sean, Maggie, Nicole, Dave Bowling, Diego, Steve Oncley

Weather: seemed nice early then dark and raining later in the day

Misc notes: Steve Oncley was working on TRAM and did some test runs
--------------------------------------------------------------------------------

* JB, SpB and MP finished removing the PAR wands from grove 1 and started 
  work on grove 2, hauled the adam and some other par equipment back to 
  the trailer 

* SpB troubleshot the CS616s some more...I think this has to continue because
  the probes still aren't working correctly. 

Site visit on Wed, Oct 1, 2008
-------------------------------------------------------------------------------
At the site: JB, NT, SpB

Weather: cooler, some sun, some clouds
-------------------------------------------------------------------------------

* tested the replacement laptop at the tower 

* tested some CS616 probes with the soil logger

  we followed the wiring scheme of the 615 for our test, i.e.
  
  you can group three probes together into one mux channel, i.e. 3 orange 
  wires into 1H, 1 green into 1L, 1 green into 2H, and the last green wire
  into 2L. 

  The black and clear wires go together to any shield or GND terminal, and the
  red power wire for each probes runs into a terminal strip which is connected
  to the 12V OUT terminal on the logger

  Here is how we connected the mux to the logger during the test:

        MUX                   WIRE                LOGGER
        ---                   ----                ------
        12V                   red                 power out 12V
        GND                   black               power out ground
        RES                   green               C2
        CLOCK                 blue                C3
        COM 2H                red                 SE 8
        COM 2L                black               SE 9
        COM 1H                white               C4
        COM 1L                green               SE 10

Tuesday, September 16th, 2008 Visit:
-----------------------------------
At the site: JB, SpB, NT.

Purpose of visit: try calibrating a LI-7500.

Weather: sunny and warm...clear skies.  classic fall
day.

--------- Misc Notes:

* drove up the grey jeep.

* there was a pine tree that looked like it was a beetle-kill right by
como creek.  we took a few photos and the holes for the beetle (if
that's what they are) are quite small.

* nicole was doing soil respiration.

---------

* hauled an N2 cylinder (number??) from the trailer out to the tower

* from XX:XX-XX:XX, changed profiler (li-6251) desiccant
  from XX:XX-XX:XX, turned off pump

  from XX:XX-XX:XX, blow test

* tested out calibration of LI-7500 (using LI-610)

   - the LI-610 was borrowed from Dave Bowling (utah)

   - at 12:49 MST, LI-610 T= 17.62 degC.

   - when we tried to change the "temperature set" knobs on
     the front panel of the LI-610 nothing would happen...it
     was fixed at 0 degC.

   - created two files with 1-hz LI-7500 data (this is done with a
     data-logging feature on the LI-7500 software).  The datafiles
     are:

       69231 Sep 16 13:30 /data/projects/NIWOT/data_logger/licor_cal.dat*
      146016 Sep 16 14:01 /data/projects/NIWOT/data_logger/licor_cal_b.dat*

   - the events are:

        In file:  licor_cal.dat

        at 13:20 MST, started running zero air through the LI-7500

        at 13:25 MST, flowed co2 from s-m cylinder JJ23865, nominal 448 ppm)
                      through the LI-7500


        In file:  licor_cal_b.dat  (started at 13:32 MST)

        at 13:32 MST, flowed co2 from JJ23865

        at 13:36 MST, disconnected.  regulator at 2 psi (this might be N2?).

        at 13:38 MST, increased regulator pressure to 5 or 6 psi.

        at 13:39 MST, disconnected.

        at 14:42 MST, connected LI-610 at 27 mmol/mol h2o.
            Tdew started at 18 deg then went down to zero.  then
            overshot zero and came back up.  went down to around
            Tdew = -5 degC.

     - after returning to campus tried to use LI-610 again and still
       could not set the Temperature.  After consulting with Dave B.,
       we sent it back to LI-COR for a re-cal.

* re-made TC connected to soil logger (am25t mux, chan_20)

Monday, August 11th, 2008 Visit:
--------------------------------
At the site: SpB/JB, SH/SL.

Purpose of visit: swap out quacker (testing).  robot.

Weather: There were puddles on the road so probably some rain the
previous night---Big CuNimbus clouds around (esp up near the divide).
Thought it would rain, but it was actually a bit sunny and nice for
most of the day.  It did rain at around 2:30'ish...

--------- Misc Notes:

* drove up the teal jeep---there was some slight problem where
anti-freeze/coolant came out while we were parked at MRS.  checked the
radiator and it seemed full there (though the res. was empty).

* stan was doing soil respiration.

---------

* started ops46; this was moving the 2-d handar from the UC logger to
the UCB logger.  New programs were written for each logger (need to
get details about the programs).  Here are some details:

   last data file:

* moved the 2-d handar at 1.5m from UC logger (chan200 at 10-hz) to
  the UCB logger (chan202 at 1-hz).

* before starting ops46 a replacement quacker laptop (a dell inspiron
7500) was tested.  the files "nwt080811.174648" and "nwt080811.181027"
are using the replacement quacker laptop.  the data are not coming in
at quite a high enough sample rate, ie:

so I'm suspecting the issue is getting the data from the quacker over
to russter2...this problem might be due to the old network pcmcia card
that we were using with the new quacker (it's my old card from the
late 1990s)???

Friday, August 8th, 2008 Visit:
-------------------------------
At the site: SpB, JB, LL.

Purpose of visit: swap out quacker (testing).

Weather: Sunny at the tower; socked in down on the plains
for most of the day.  A HUGE cap cloud up on the divide.  Thought
it might rain, but the weather stayed nice all day.

--------- Misc Notes:

* Took up the teal jeep (grey jeep still at the shop).

* LL was working on PAR/Tsoil network.

---------

* at 10:00 MST, put an approx 4 deg angle on KZ PAR sensor (low
end toward North, high end toward South).

* at approx 11 MST, swiped krypton hygrometer.

* used sextant to site prop-vanes.  (add details here):

* tried to check on soil moisture probes N1/N2 (to confirm which one
was at which depth).  They are buried very deeply and this was not
going to be easy without completely digging up these sensors.  So rather
than completely disturb the soil we left them as-is.  The connections
at the soil logger are:

  N1 = chan23
  N2 = chan24

* strung up a section of steel cable over the MRS snow temp
probes (the fishing line had broken).

* tried to figure out where the problem was with the broken probe
(probe#2/Tb/"far sensor from tree").  the clock port was showing 5V
(and the other two sensors showed approx 0.4 V).  When we disconnected
the wires then the clock port was fine...we found a short between the
clock wire (black) and power/+5V wire (red).  So we disconnected the
sensor from the wire and the short dis-appeared.  (this indicates the
short is internal to the sensor).

called MRC (253.851.3200) and talked to Pat Martka (who sent the
original fax to Mark Loseleben).  They still make these sensors and
are going to get back to me with some other ideas about possibly
fixing this one.

* tried to check on the intermittent TC connected to soil logger
am25t, but they all appeared to be working??

     21,     at +20cm, located closest to tree snowT probes, 48cm North of "tree" probe (A3537).
     22,     at -20cm, located between tree and mid snowT probes, 118cm North of "tree" probe and -35cm from mid probe (A3537).
     channels added on 10/30/07:
     23,     at 0cm, located between mid and far snowT probes, 67cm from "mid" probe (A3537).
     24,     at -20cm, located closest to tree snowT probes, 48cm North of "tree" probe (A3537).
     25,     at -20cm, located between mid and far snowT probes, 67cm from "mid" probe (A3537).

 * when i was checking the am25t, chan20 had a loose wire which i
   re-attached.  Also, reconnected chan21 since this was giving
   intermittent data.

* brought N2 cylinder CC262308 back to campus.

Monday, August 4th, 2008 Visit:
-------------------------------
At the site: SpB/JB, SH/SL.

Purpose of visit: swap out quacker (testing).  robot.

Weather: There were puddles on the road so probably some rain the
previous night---Big CuNimbus clouds around (esp up near the divide).
Thought it would rain, but it was actually a bit sunny and nice for
most of the day.  It did rain at around 2:30'ish...

--------- Misc Notes:

* We went to use the grey jeep in the morning---it was sitting in the
parking lot with a FLAT tire (that had clearly been driven on).

 Subject: gray Jeep


 Hi everyone.

 A few of us met on campus this morning (Mon. 8/4) to take the Jeep to
 Niwot Ridge and discovered two flat tires. The front right tire is
 totally deflated and the rear right tire is on its way. Does anyone
 know anything about this? Did anyone use the Jeep over the weekend
 and/or notice low tire pressure at any time recently ?

 We are bringing the Jeep down to the motor pool in a little bit so the
 two tires can be repaired. We'll have the green Jeep for today and
 most likely will have to return it tomorrow morning and get the gray
 Jeep back (which should be fixed by then).

 Jeff

the "mystery" as to what happened has not been solved.

* stan and sam were doing soil respiration.

---------
* at approx 12:30 MST, Changed profiler (li-6251) dessicant

* note, my watch is around 10 seconds slow (relative to russter2 time).

* from 11:30-11:45, messed around with the 16m prop-vane.  From approx
  11:50-11:55 the prop vane was pointed directly along the boom.

  -- note, we were connected to the met logger with a laptop so we
     don't have any WD data for the time period we did this.  (need
     to re-do).

* from 12:23-12:24 MST, fixed the 25m prop-vane.  at 12:24 MST, held
  prop to create a short period of zero WS.  a look at the
  WD data shows the stats to be:

  mean(WD) = 379.407 = 19.407 (if remove 360), std dev= 0.975

* once we know the direction relative to the boom then we just
  need to determine boom directions (with Steve Oncleys sextant).

* from 12:44-12:50 MST, messed around with flow rates and pressures
  for the LI-6262/EC system.  details:

                             sample     span     N2
  at 12:44 MST,  Pres         54        54.9     60.3
                 Flow        8.55       8.72     9.84

  decreased N2 pressure slightly (from 20-18 psi) then get:
  (and maybe a small tweak to the needle valve??)

                             sample     span     N2
  at 12:49 MST,  Pres        54.2       55.13    55.29

 HI Andrew,

 on june 12th we turned on the TECO system and it was running
 fine...looking at the co-var voltages the pump died 10 days later
 early in the morning on 22 june.  you can double-check it, but it was
 definitely not moving air yesterday...

 that pump seemed a bit pricey to me, so thanks for the warning about
 this.  there's a slim chance i'm going up on thursday, but i will
 definitely be up on friday.

 if you need me to order anything or do something else to help
 with the ozone replacement pump just let me know...

 thanks,

 Hi all
 A new warming experiment is being started at the MRS this summer.  It
 requires a few changes to our current power setup, these changes are
 estimated to take about 6 weeks durring which time there will be many power
 outages above C1.  I have been told that nothing at C1 will be affected.
 Below I have made a short list of users who may be affected by these
 outages.  Please respond with any concerns you may have regarding timing and
 duration of these power outages, and pass along to anyone I may have missed.

 The equipment I have at the Soddie, and Saddle can have a maximum power
 outage of 2 days and still be operational.

 Cheers

Wednesday, July 23rd, 2008 Visit:
---------------------------------
At the site: SpB, MP/JH/CB, NT/SL.

Purpose of visit: PAR wands.

Weather: Overcast in the morning.  Then some rumbles of thunder in the
afternoon and a quick rain shower.  (we hid out in the USGS "hut").

--------- Misc Notes:

* Jeff is on vacation.

---------

* tried to help with the wands.  We swapped out a card at Grove 1, and
then moved the ladder over to grove 2 (and got started on one of the
trees there).

* note, Gordon set things up so the "grove" data are archived on
russter2.  Then each night (or morning) they are copied down to NCAR.

the files look something like:

dir /media/isff1/projects/NIWOT08/raw_data/ | grep 'Jul 28'

not sure why grove2 data is missing?

Monday, July 21st, 2008 Visit:
------------------------------
At the site: SpB, MP/SH/CB/RaM, NT/SL.

Purpose of visit: replace filters in EC/li-6262 system.

Weather: hot in the morning and then cool and cloudy in
the afternoon (seems like the Monsoon has started).


--------- Misc Notes:

* Jeff is on vacation.

---------

* messed with the flow rates/filters for the LI-6262.

   - at 11:38 MST, the flow rate was around 6.45 (lpm?).
     disconnected the pump at the side of the LI-6262 box.
     disconnected the tubing from sample IN/OUT and connected
     these together (to prevent dust, etc from entering sample cell).

   - from 11:40-12:02 MST, replaced the 2-micron NuPro filters
     at the inlet and also in the LI-6262 box.  Note, I first
     did the inlet and that did not make a big change in the flow
     rate.  However, replacing the one in the box caused the
     flow rate to increase dramatically.

   - at 12:07 MST, i re-adjusted the needle valve for the N2/span
     to increase the flow during cals (which i had decreased on
     friday).

   - at 12:09, back to sample...results from 12:10 MST cal:

             Pressure mV         Flow
  sample       54.2              8.59
    span       58                9.75
      N2       56.6              8.65

* swapped flasks at the west robot.

Hi All,

see below for important info from Dave Bowling about the shed at the
base of the Monson AmeriFlux tower...please forward this email to any
others that might use the tower/shed that I'm not aware of...Andrew, I
don't have the email for your assistant from France...

also, I wanted to make sure everyone is aware that Jeff and I put a
new fire extinguisher out in the shed last month...it's very
dry/crispy right now up at the site so please be aware of where the
extinguisher is located so you can find it in a hurry....

Subject: shed rules at Niwot


Sean - can you please forward this to anyone you can think of who might
be users of the shed?
Thanks,
DB


Hi all,

We have had some inadvertent problems with users of the shed at the CU
flux tower.  The shed is there for one reason - to house the TDL so that
high-quality measurements can be made.  The quality of measurements is
being compromised by users of the shed, so hopefully some information
will help.  Please share this email with anyone in your group who might
be inclined to use the shed.

1) You may store things in the shed.  It's ok to be inside - your
presence does not cause problems.  It's ok to use the internet
connection inside (labelled "outside world").  If you're at the site
overnight you are welcome to sleep inside (if you can fit), you can use
it to get out of the rain, eat your lunch, etc.  But you _must _follow
the rules below.

2) Please NEVER leave the doors open.  This causes temperature-related
problems and most data are bad when the doors are open.  Please don't
second-guess me on this because you think it's too hot inside or
something.  Keep the doors shut unless you are moving through them.

3) Please NEVER touch the TDL (the big white instrument inside).  NEVER
set anything on it, bump it, kneel on it, sit on it, etc.  Bumping by
shed-users recently caused the TDL to be knocked out of optical
alignment, which is a problem that requires me to visit from Utah to fix.

4)  If you do accidentally bump it, please email me immediately and tell
me so.  I can check the alignment from Utah and I'd much rather know
about it than lose a month of data.

5) Be very careful not to kick the regulator pressure knobs on the gas
tanks that are on the floor inside.

6) Please minimize vibration while inside the shed.

Thanks for your help!

Best,
Dave

------------------------------
At the site: SpB, DB, SO, LL.

Purpose of visit: change out MgClO4 for prof system.

Weather: cool and overcast.  some clouds.  i think it was
fairly pleasant...don't fully recall.


--------- Misc Notes:

* drove up in the CU suburban (extra one for the flux class).  Duane
  had his sign up and was running his pump.  Parked below C1 (near the
  meadow).

* D. Bowling was improving the ventilation in the shed and also moving
  around some of the laser inlets.

* Jeff is on vacation.

---------

* from 11:30 - 11:48 MST, swapped out the dessicant on the profiler (li-6251).
    - at 11:30 MST, did zero (value is approx 0.006 mV).
    - at 11:46,  did zero + blow test (ok).
                (zero is approx 0.001 mV, span is approx 1.378 mV).
    - at 11:48,  back to auto mode.  flow rate at ~15.

* at 11:51 MST, tightened up the span/N2 valve in the LI-6262
  box..this brought down the flow rate during the LI-6262 cals to
  approx 6.45 which is what it is during the sampling (and seems too
  low).

* did a (very) short stint of work on tram (SO was also there working
  on tram).

Purpose of visit: robots, some tower stuff, help with TRAM.

Weather: Don't recall.

--------- Misc Notes:

* drove up in the CU suburban (extra one for the flux class).

* helped SO at tram in the afternoon

* the summer "flux" class at MRS started this morning.

---------

* brought the N2 cylinder (CC193097) from Como Creek out to the flux
  tower, and brought a new span cylinder (CC282376) from the trailer
  to the tower.  Note that CC193097 belongs to Kurt Chowanski---need
  to check if he wants it back or we should return it to airgas
  ourselves??

* also brought co2 cylinder (CC282376) airgas value= 405.3 ppm out
  to the tower (it's lying on the pallete inside the fence).

* from 10:30-11:15 MST, replaced the ec gast pump.  The old pump is still
  usable, but Andrew said the GAST pump with the ozone flux system was
  fried so thought that he could use the old pump and we'll use the
  new one (note, the flow rate is still rather low for the EC system).

* at 11:30 MST, cleaned the krypton optics

* at 11:45 MST, connected power to fan for 2.5m REBs Rnet sensor (used
  a regulated 12V ac/dc cube for this to try and minimize stressing
  the ucb cr23x logger and battery).

* swapped flasks at the robot

* checked the flow meter for the prof pump...moved back up to "15" (prof 
  "flow-meter" ball was at ~13, increased the flow to 15) 

* N2 @ 490, span @ 530

* between 13-14 MST, chan 204 (met logger) was dropping data points 
  (seems ok now)

-------------------------------------------------------------------------------
At the site: JB, SpB, NT, SL, SH, JH

Purpose: NT and crew to deploy sap-flow sensors, JB and SpB to do some tasks

Misc. notes: drove up to C1 in the Jeep; encountered a large black bear on the 
road heading down from C1, down by the "short steep section," in some aspens
near a clearing on the north side of the road. This was a healthy looking bear 
but it did not seem aggressive. When we got closer for a better look it 
quickly made its way to the far side of the clearing and headed for the woods 
to the north of the road. Great sighting so close to the trailer.

Jeff,

My question was whether you noticed any air flow in the tubing while
you were changing the inlets??  (assuming the big pump was left
"on")...if you did notice air getting sucked into the tubing then that
would tell us that the knf pump at the base of the tower was running
at that time...if you did NOT notice air being drawn in, then that
would indicate the pump was probably dead at that point...the suction
is not super-strong, but can be noticeable (you can check it for
yourself sometime by putting your finger over an inlet)...

anyway, i was just trying to pin-point what date the KNF pump died...

  Subject: extention cords at the CU tower...


  Hi,

  quick update--today we coiled up four 100' extention cords that were
  running from the North canopy tower out to the PAR site from last
  summer (i'm not sure who these belong to, eol or maggie?)...if they
  need to be returned to eol let me know and i'll bring them back to
  NCAR.  i assume that these cords were not needed in that location and
  probably better to take them out of the weather, etc.

  we also coiled up three 100' extention cords that were running east of
  the tower (jia was using these).  note: there is still one cord that
  runs to the east of the tower (it's a thick black cable)...and one
  orange 100' extention cord sitting out by the end of the black
  cord...if you follow the black cord east from the tower you will find
  the end in a tree, ie:

    http://urquell.colorado.edu/photos/080703/pic00026.jpg

  the seven coiled 100' extention cords are in a green garbage can that
  is right behind dave bowlings shed, ie:

    http://urquell.colorado.edu/photos/080703/pic00029.jpg

  bottom line: we have LOTS of extention cords at the site and you
  probably don't need to buy any new ones....also, i did not move the
  extention cords that are going from the main tower to the "north
  tower" (ie, the tower that lynette installed last summer).  i assume
  these are going to be used at some point...i noticed that this string
  of extention coords (i think it was at least six 100' cords) was not
  running anything, but it was plugged in...i unplugged it.  if you are
  not using a power cable, it's probably best to unplug it...

  Jeff and i also found what looked like a dog bowl along the trail near
  como creek..it had what looked like a mix of dog food and pine needles
  in a plastic bag in the bowl...not sure where it came from, but we
  threw away the dog food/pine needles and left the dog-bowl in the
  trailer.  i suggest that we not leave dog food, people food, etc
  anywhere that is accessible by the wildlife in the area...

  also, as we were leaving, jeff, stan and i saw a fairly large-size
  black BEAR just before the steep part of the road (a bit below
  C1)...so there is a bear in the neighborhood.  i have a few photos of
  the bear which i'll upload next time i'm up in the trailer...

*=Sascha Oncley

Purpose: continue tram work

Misc. notes: drove up in an EOL vehicle 

Site visit on Thursday, June 26, 2008
-------------------------------------------------------------------------------
At the site: JB, SO, MP, NT, CB, SL, SH

Purpose: JB and SO for tram work; MP & Co. started testing the ladder method 
         for wand deployment

Misc. notes: JB and SO drove up in an EOL vehicle

Site visit on Wed, June 25, 2008
-------------------------------------------------------------------------------
At the site: JB, SO

Purpose: work on tram setup

Weather: warm, with afternoon thunder and lightning

Misc. notes: drove up in an EOL vehicle

Thursday, June 19th, 2008 Visit:
--------------------------------
At the site: SpB, JB

Purpose of visit: swipe krypton, move 2.5 REBs sensor and finish the
setup of in-canopy radiation sensors.

Weather: Hot.  It felt like July...there were a few gusts of wind, but
generally calm weather.  Some nice Cu clouds in the afternoon...

--------- Misc Notes:

* drove up the CU suburban (grey jeep is in alamosa with Amy).

* Hauled up the 40' ladder that is going to get used this summer...we
carried it out to near the tower.

* had a short discussion with Duane about calibrating gas cylinders...

---------

* was able to connect to the LI-7500 at 2.5m...note, you need a null
modem to go along with the connection cable they give you (or you need
the special cable from LI-COR).  We check the AGC value (around 65).
Cleaning the optics did not change this value much.  We swapped the
small desiccant/soda lime canisters as per the instruction manual.

* moved the 2.5m PAR sensors at the mini-tower (since tram plans to
use this tower).  We decided to put some cross-bars in a tree and then
mount the radiation sensors across these bars.  It's not ideal, but
it's the best solution we could come up with and still use the same
logger, not mount a new tower, etc.

* tested out Steve onlceys sextant...it seemed to give values that
were in very close agreement with angles from the map i made of the
area.

* cleaned krypton optics

* replaced all of the profiler inlet filters

* swapped desiccant at the profiler, blow test and zero both good

Wednesday, June 18th, 2008 Visit:
--------------------------------
At the site: SpB, JB, SL, SH

Purpose of visit: mess around with the LI-7500, power
for forestcam and swap flasks.

Weather: Calm and pleasant.  Clouds built up in the
afternoon and there was a brief rain shower.

--------- Misc Notes:

* drove up the CU suburban (grey jeep is in alamosa with Amy).

* Stan and Sam were finishing up some soil respiration measurements.

* the snow is basically gone.  it is still possible to find a few
patches in the forest.  the mosquitos have arrived.

* ran into John Knowles who saw a mooose right after we talked
to him.

* Forest service people (MIke Ryans group) were out doing stuff.

* there is a bunch of crap in the trailer from Noah Fierers group...no
on told us about this??...

---------

* connected with "plumwood" to the network at the bowling shed.
worked with no problems.

* was able to connect to the LI-7500 at 2.5m (sn 75H-0082)...note, you need 
a null modem to go along with the connection cable they give you (or you need
the special cable from LI-COR).  We check the AGC value (before 69%, after 
64%). Cleaning the optics did not change this value much.  We swapped the
small desiccant/soda lime canisters as per the instruction manual.

* moved the 2.5m PAR sensors at the mini-tower (since tram plans to
use this tower).  We decided to put some cross-bars in a tree and then
mount the radiation sensors across these bars.  It's not ideal, but
it's the best solution we could come up with and still use the same
logger, not mount a new tower, etc.

* swapped a full set of robot flasks (done=1).  I believe this
is the first full swap of the season.

* disconnected power from both the cr10x and the MRS logger cr10 (at
the North Canopy tower).

* downloaded logger data:

--------------------------------
At the site: SpB, JB, DB, MP, NT, CB, SH

Purpose of visit: mess around with the LI-7500, power
for forestcam and swap flasks.

Weather: Pretty windy.  Clear and cool.

--------- Misc Notes:

* drove up the CU grey jeep.  Nicole and her gang went up in the CU
blue jeep.

* the snow is almost all gone.  there are still some spots with
drifts.  the trail is quite dry.  the small "first creek" is flowing.
No bugs yet.

* Dave bowling is servicing the last and also doing some work on the
shed...

---------

* span @ 750 psi, N2 @ 1290 psi

* robot, done=2, swapped four flasks

* turned on AT's slow O3 sensor

* snow depths at snow temp probes:  (according to jeff=0).

* moved the power for the forestcam to the UPS in the action-packer at
  the first level of the tower (plugged right into the back of the UPS
  with the blue extention cord).

* set up an internet cable in dave bowlings shed.

* sent an email about the CU network (see "Stuff at CU site for this
  summer, etc..."  from June 13th, 2008):

* downloaded NCTC logger data:

Site visit on Wednesday, June 4, 2008 (JB)
-------------------------------------------------------------------------------
At the site: JB

Purpose of visit: perform maintenance on the robot, start summer weekly 
sampling, cal and post-cal some co2 cylinders

Weather: rain on and off, cool

Misc. notes: drove to C1; Duane good-naturedly criticized our trailer 
calibration system and procedure, and gave us a high-quality standard to 
test the accuracy of our system...plan to do this next visit
-------------------------------------------------------------------------------

* span @ 840 psi, N2 @ 1525 psi 

* brought 2 empty N2 cylinders back to Ramaley from the trailer

* performed some maintenance on the robot, started summer weekly sampling:

  > replaced all o-rings in the ultra-torr fittings, replaced a few missing
  ultra-torr ferrules, loaded the robot with 15 flasks, started summer weekly
  sampling

  > to go from winter (i.e. 4 flasks) to summer (i.e. 15 flasks) sampling, do:
    *0, *4A, AAAAAAAAA (that's nine), 0A, *0

  > to go from bi-weekly to weekly sampling, do:
    *0, *4A, 7A, *0

  > NOTE: The "*0" command saves whatever changes were just made and restarts 
    the logger, thus the program. So, if making both changes together,
    omit the "*0" following the first change, then enter it following the
    second change and the program will be updated with both changes 
    simultaneously. After entering "*0" the logger will hang for about 1
    minute while it updates the program. You'll see "MODE 00" on the screen. 
    This is okay. Eventually the logger will start running Table 1 again and
    you are good to go. DO NOT ALSO POWER CYCLE THE LOGGER WITH THE LITTLE
    GREEN PLUG...The "*0" command effectively does this. 

* post-calibrated airgas cylinder CC18996, calibrated airgas cylinders 
  CC282352, CC282376:

  > for these cals I created the file cal_co2_080604.dat, and this is located
    on russter2 in /home/staff/sburns/docs/calibrations_co2/

  > we now have 3 co2-in-air cylinders in the trailer calibrated and ready 
    for the tower: Airgas SG9151924BAL (was already in the trailer), and the 
    2 new ones I brought up Tuesday and calibrated Wednesday (Airgas CC282352 
    and CC282376)

   
* here are the results from the calibrations run in the trailer
        (see ~sburns/docs/calibrations_co2/cal_co2_080604.dat)

       Post-cals:
       ----------
       at 300 psi, CC18996 values= (417.17+416.24+416.58)./3= 416.66 ppm.

       Pre-cal:
       --------
       at 2150 psi, CC282352 values= (398.76+397.42+397.36+397.54)./4= 397.77 ppm.  (airgas co2 value = 397.7 ppm)
       at 2150 psi, CC282376 values= (406.49+405.5+405.62+405.35)./4= 405.74 ppm.  (airgas co2 value = 405.3 ppm)

Subject: Re: monitor for russter2...


This has nothing to do with power but with the fact I stopped the
graphics interface so that Jeff could see if the monitor works in
command-line mode.  I totally forgot this does not work with the
UPS and the ups clearly decided to shut the system down after I
did this.

So, Erinn's message, although absolutely true, is irrelevant here.

Thursday, May 15, 2008 site visit
--------------------------------------------------------------------------------
At the site: JB, SpB

Purpose of visit: To start cleaning the trailer and hauling out garbage; to set
up the LI-6251 for cylinder calibrations in the trailer; to fix T3 on the tower;
to bring some cylinders up to the site from Ramaley

Weather: mostly cloudy skies, with some heavy intermittent snow

Misc. The road to C1 is open! Drove to the trailer with Kurt in the back with
the cylinders

--------------------------------------------------------------------------------

* at 14:18 MST, fixed T3 on the tower--the wires had come uncoupled

* snow depths:

         closest to tree = 77
  TP101 461 middle probe = 100
          farthest probe = 108

* started massive cleaning of the trailer

* here are the results from the calibrations run in the trailer
        (see ~sburns/docs/calibrations_co2/cal_co2_080515.dat)

       Post-cals:
       ----------
       at 450psi, CC240435 values= (402.34+403.68+403.51+404.02)./4= 403.38 ppm
       at 350psi, CC187116= (405.04+404.76+404.89+404.53)./4= 404.805 ppm
       at 400 psi, CC66823= (333.37+333.7+333.74+333.76)./4= 333.64 ppm.

       Pre-cal:

       at 1700 psi, SG9151924BAL = (408.42+407.7+408.27)./3 = 408.13 ppm.


* Brought some old cylinders back to campus, brought some new cylinder up to 
  the trailer, calibrated and post-calibrated some cylinders, Here's the skinny:

  brought up:
  ==================================================
  CC262308, airgas, N2
  CC68888, airgas, co2 in N2? 412.9 ppm +/- 2%

  brought down to return to Airgas
  ==================================================
  CC199706, airgas N2
  CC125555, airgas N2
  CC240435, airgas, co2 in air, 407.8 ppm
  CC187116, airgas, co2 in air, 400.0 ppm
  CC66823, scott-marrin, co2 in air, 334.86 ppm

  the co2 concentrations are nominal ones from airgas

  we also did a cal on a new co2 cylinder that was already in the trailer
  (#?), and this is ready to go out to the tower

  

Sunday, May 4th, 2008 Visit:
----------------------------
At the site: SpB

Purpose of visit: download logger data, check on the
li-6262 flux system.

Weather: Very Sunny and warm.  A few wind bursts, but generally
calm.

--------- Misc Notes:

* drove up my own jeep.  hiked up the powerline.

* the snow is really starting to go fast---the powerline is nearly
snow-free.

* Kurt and Todd A were up there...trying to get the tundracam up and
running...

---------

* snow depths at snow temp probes:

              closest to tree = 73 cm (assuming top tape is 80cm--need to double check)
       TP101 461 middle probe = 93 cm
               farthest probe = 101 cm

* noticed that the support cable holding up the 25m REBS Q*7 sensor
was detached...it was just loose and had blown over near the boom for
the CNR-1 sensor...it looks like maybe the clip holding the cable to
the boom had come loose (since no parts were missing).  I reconnected
and tightened it---this will probably have some small effect on the
alignment of the REBS sensor.

* from 11:42-12:30 MST, swapped out the 2-micron nupro filter at the
inlet for the LI-6262 ec system.  the plastic nalgene cover over the
inlet was completely trashed/gone.  So, I found a nalgene in the shed
and used that to replace the cover...disconnected the lines in/out of
the LI-6262 so no flow was passing through the li-6262 during filter
swap.  ran for about 10 minutes after swapping to try and avoid dust,
etc getting into the cell...sequence:

 - at 11:40 MST - did zero, then disconnected LI-6262
     with N2, co2 = 175 mV
              h2o = 179 mV
     sample flow approx 7.77

 - from 11:45-12:20 MST made changes, swapped filter
      with N2, co2 = 189 mV
               h2o = 190 mV
     sample flow approx 8.26

 - at ~12:30 MST, back to sample


* downloaded all logger data except for UC and UCB (reset time on
all loggers--most all were within 30 sec of russter2 time):

Site visit on Friday, April 18, 2008
--------------------------------------------------------------------------------
At the site: JB

Purpose of visit: a few routine tasks (e.g. get snow depths, swap flasks at the
west robot, swap desiccant at the LI-6251, check on the gas cylinders at the
tower), collect needles for Jia, haul some cylinders around, try to make the 
21x in the trailer save 5-min avg. data

Weather: warm, sunny, breezy, snow very heavy and very wet

Misc: Drove a Jeep to the Marr Lab and hiked to C1

--------------------------------------------------------------------------------

* swapped 4 flasks at the west robot, hauled back a suitcase to mail to Utah

* hauled empty N2 cylinder CC193045 back to the trailer

* snow depths at snow temp probes:

              closest to tree = buried
       TP101 461 middle probe = 121 cm
               farthest probe = 130 cm

* span @ 1250 psi, N2 @ 1325 psi

* swapped desiccant at the LI-6251:
            11:18 MST, 0=0.002
            11:38 MST, 0=0.001

* downloaded from soil logger...didn't know if it had been done earlier in the
  week so I figured it was worth investigating...soil data had been grabbed on
  Tuesday, so there is a small soil file from Friday

* put the SC32B in Noah's logger box
  in addition, there is one SC32A on campus, and another SC32A in the trailer

* tried to connect to the 21x in the trailer but couldn't...spent almost 30
  minutes trying all possible combinations of serial cable, SC12 cable and
  SC32A interface but couldn't connect...power at the logger was fine and the
  battery was fine...had trouble connecting to this logger the last time I 
  wanted to work with it but after about 5 minutes could finally connect...

* brought the storage modules and pcmcia card up to the trailer

* dug out the lowest prof inlet

* NO snow on the 2m REBS Rnet sensor

Site visit on Tuesday, April 15, 2008
--------------------------------------------------------------------------------
At the site: JB, SpB, JH

Purpose of visit:

(JH/JB) Needle collections, snow pit, soil collection, 99% 13C experiment

(SpB) a few routine site tasks (e.g. clean krypton optics, get snow depths,
adjust the flow rates in the LI-6262 sample cell), maybe set up the LI-6251 in
the trailer, maybe set up the accelerometers on the tower

Weather: very warm, a bit breezy

Misc: Drove the gray Jeep to the Marr Lab, hiked to C1. Saw a robin on the road
about 200m from the trailer.

--------------------------------------------------------------------------------

* Snow depth at the snow temperature probes:
       closest to tree =  covered
TP101 461 middle probe =  111 cm
        farthest probe =  118 cm

* at 10:30 MST, fixed power connection for NCTC logger.  When the
power supply was moved (on 3/19) from the 1st tower level up to the
platform level (right next to NCTC logger) the wires were still
connected to the green plug at the logger---the far end of the wires
must have touched, shorting out the power.  after these wires were
removed from the green plug, everything came back and worked normally.

* at 11:35 MST, swiped krypton hygrometer

* at 11:45 MST, moved 12.5 li-7500 closer to ati sonic

* from ~11:50-11:55 MST, adjusted flow rates in the LI-6262 sample cell

* collected needles from all 18 of Jia's "collection trees"

* dug a snow pit to get a soil sample

* completed one cycle of Jia's 99% 13C experiment on the 10m platform on the
  tower

* dumped a pcmcia card at Lucas's computer before hiking up to C1

* swapped pcmcia cards at the mrs logger and dumped those data at Lucas's
  computer before leaving the MRS

* logger data downloaded:

    MRS time = 12:49:14 MST
   true time = 12:52:00 MST.

Wednesday, April 2, 2008 site visit
--------------------------------------------------------------------------------
At the site: JB, SL, NT, Nate M, Chris

Purpose of visit:

(JB) To swap N2 cylinders at the tower (priority), download some logger data, 
swap flasks at the west robot, and do a few other small tasks.

(NT, SL, Nate M, Chris--a huge Alaskan) To remove all of the snow exclusion 
fencing and do some snow manipulation.

Weather: warm, sunny, calm, but very wet from melting/dripping snow.

Misc. Packed five people (including a huge Alaskan guy named Chris) into the
gray Jeep. Parked at the Marr Lab and hiked to C1.

--------------------------------------------------------------------------------

* downloaded from soil, tcs and noah loggers, and swapped pcmcia cards at the 
  mrs logger

* snow depths at snow temp probes:
                closest to tree =  100 cm
         TP101 461 middle probe =  110 cm
                 farthest probe =  118 cm

* swapped N2 cylinders at the tower:

  Retired cylinder CC193045 @ empty
  Started cylinder CC198701 @ 1900 psi

  Leak check info:
  
  2:15 MDT 1900 psi
  4:15 MDT 1900 psi

* dug out the lowest prof inlet on the mini tower

* confirmed that the new Gelman filters are in a cupboard in the trailer (down
  by russter2)

* confirmed that the Gelman filter (new 1/2008) is on the co2 prof inlet on the
  tower (but there is no cover over it)...still need to add a soda bottle

   

Wednesday, March 19, 2008 site visit
--------------------------------------------------------------------------------
At the site: JB, SpB, NT, EB, SLS, AW

Purpose of visit: 

(JB, SpB) to swap flasks at the west robot, download some logger data, move the
NCTC logger's charging system into the empty Campbell box next to the NCTC
logger, and replace the repaired cr23x UCB logger (remove Jia's 10x).

(NT, EB, SLS, AW) to work at NT's snow manipulation plots in the eastern
forest

Weather: very windy most of the day, but mostly clear and sunny

Misc. notes: Drove the purple Prius to the Marr Lab and hiked to C1. Erin
skinned up to C1 on his K2 Piste Stinx 180s. Duane drove up to C1 in the snow
cat, so we got to walk Bear back down to the Marr Lab at the end of the day
because he doesn't like the snow cat. Steve Siebold was back in his office at
the Marr Lab after a ~6 week hiatus.

--------------------------------------------------------------------------------

* swapped four flasks at the west robot

* Snow depth at the snow temperature probes:
       closest to tree =   82 cm
TP101 461 middle probe =  102 cm
        farthest probe =  110 cm

* replaced the UCB 10x (Jia's) with the repaired cr23x; the soil moisture
  sensor seemed to be working fine once the cr23x was swapped back into place 

* moved the NCTC logger's charging system into the empty Campbell box next to 
  the NCTC logger on the tower platform

  --> For the 2-D sonic's power, we used a 300mA 120VAC to 12VDC adaptor. The
      adaptor end is plugged into a power strip in the quacker's box, and the
      bare wires are wired into a small terminal strip (the bare wires coming
      from the sonic are wired into the other side of this terminal strip).

  --> the charging unit that was previously located on a lower level of the
      tower was moved into the empty Campbell box that sits right next to the
      NCTC logger's box on the ~10m platform. The dead battery in the charging
      unit was replaced with a new YUASA 12 VDV 7.0Ah battery. AC power for the 
      charging unit still comes from the lower gray "power box" on the tower,
      but is now carried up to the charging unit via the blue extension cord
      that had been sitting unused in the shed. This extends up and into the 
      Campbell box on the platform, and the original AC-DC adaptor from the
      gray power box plugs into it. The adaptor's bare wires wire directly into
      the 2 "chg" terminals on the charging unit's terminal strip. Another
      length of wire runs from one each of the "+12V" and ground terminals to
      the little green plug on the logger.

* downloaded from NCTC, UCB, soil, Tcs, and swapped pcmcia cards at the mrs 
  logger

* hauled 2 empty cylinders back to the trailer

  --> there were two empty gas cylinders (I think one N2 and one span?) inside
      the tower fence that got hauled back to the trailer and secured in front
      of the trailer. In addition to the N2 cylinder currently running at the
      tower, there is one new tank waiting in the trailer and another new tank
      waiting out at Como Creek (where hydra used to reside)

* helped Nicole and Co. shovel snow for a little while at her snow manipulation
  plots in the eastern forest

* info about march 18th 2008 changes to ntp on quacker:

the only file changed on the quacker was:

-rw-r--r--    1 root     root         2831 Mar 18 13:25 /etc/ntp.conf

the line:

restrict russter mask 255.255.255.255 nomodify notrap noquery

was commented out, and one line (taken from russter2) was added, ie:

# -- CLIENT NETWORK -------
# Permit systems on this network to synchronize with this
# time service.  Do not permit those systems to modify the
# configuration of this service.  Also, do not use those
# systems as peers for synchronization.
# restrict 192.168.1.0 mask 255.255.255.0 notrust nomodify notrap
restrict 10.0.0.0 mask 255.255.255.0 notrust nomodify notrap


# --- OUR TIMESERVERS -----

# Permit time synchronization with our time source, but do not
# permit the source to query or modify the service on this system.
# restrict russter mask 255.255.255.255 nomodify notrap noquery
server russter

then we did:

[root@quacker root]# /etc/init.d/ntpd stop
Shutting down ntpd:                                        [  OK  ]

to check that ntp is running do (on russter2):

ntpq -p quacker
     remote           refid      st t when poll reach   delay   offset  jitter

Thursday, March 6, 2008 site visit
--------------------------------------------------------------------------------
At the site: JB

Purpose of visit: to download from all of the tower loggers, the soil and tcs
loggers, and swap pcmcia cards at the mrs logger; to swap flasks at the west
robot, download the data and change the fudge day (a.k.a. work day); re-connect
the 21x in the trailer, re-send the program to it and make sure it is connected
to the edgeport; get "ucb10x_2.csi" (the program currently running on the ucb
logger) off the usb key and into /data/projects/NIWOT/data_logger/logger_programs/;

Weather: cold but calm and sunny most of the day

Misc. notes: Drove the gray Jeep to the Marr Lab. The digging in the parking lot
is finished and the bathrooms are open again. The Jeep didn't have a driver's
side windshield wiper so I couldn't use the wipers at all. The rear wiper didn't
work. Hiked to C1. Quite a bit of new snow at the site. About 6 inches new on 
the way out to the west robot.

--------------------------------------------------------------------------------

* swapped 4 flasks at west robot, downloaded data and changed the fudge day 
  from 5 to 4, so work days are now Wed/Thurs 

* span @ 1525 psi, N2 @ 1025 psi

* re-connected the 21x in the trailer, re-sent "21trlr.dld" then captured some
  data in hyper-terminal (the *.txt file of this data is in the logger data
  directory on russter2

* added "ucb10x_2.csi" to the logger programs directory on russter2

* hauled the dead ucb battery from the shed to the trailer

  ** when I replaced the entire battery/charging system for the ucb logger back on 2/22/08, 
     I needed a known functioning charger so I took the one that had
     been running with the 21x and its battery in the trailer. Thus, in order to
     re-connect the 21x today I needed a functioning charger. There were two
     chargers in the trailer: one that SpB had noted "might be broken" and the
     one I pulled from the ucb logger on 2/22, also noted (by me) "broken?"
     Both of these chargers tested out to be broken. Luckily I found a good
     charger in the shed (this charger was in the action packer that also 
     housed the good battery I swapped for the dead ucb battery on 2/22). With 
     only one good charger that I could find, I couldn't try charging the dead
     ucb battery--this is something to try when we buy a few new chargers, or 
     we could use the one that is kept next to porter in JB's/MW's/SpB's office,
     but it is nice to have one always on hand in the lab...

Friday, February 22, 2008 site visit:
--------------------------------------------------------------------------------
At the site: JB

Purpose of visit: address the possibility of a power problem at the ucb logger,
abd try to get that data streaming into the data system again

Weather: warm, sunny, mostly calm

Misc. notes: drove my car up to the Marr Lab, hiked to C1

--------------------------------------------------------------------------------

* tested the cr23x (ucb) in the trailer and confirmed that it is unresponsive

* replaced the entire battery/charger system for the ucb logger 

* got the data from ucb (Jia's cr10x) going back into the data system again (was a matter of sufficient power to the logger) 

* started running "ucb10x_2.csi" at the ucb logger (this program uses 
  instruction P138 for the cs616 water content reflectometer), although there 
  still seems to be something going on with this sensor; investigate when the 
  cr23x is returned 

Thursday, February 21, 2008 site visit:
--------------------------------------------------------------------------------
At the site: JB, SpB

Purpose of visit: swap flasks, swap sonics at top of tower, mess with the ucb 
logger

Weather: cold, snowing

Misc. notes: drove the teal Jeep to the Marr Lab, hiked to C1

--------------------------------------------------------------------------------

* swapped 4 flasks

* Snow depth at the snow temperature probes:
       closest to tree =   67 cm
TP101 461 middle probe =   83 cm
        farthest probe =   91 cm

* upgraded the firmware on jias cr10x, ie:

cr10x (jias), from *B, get:  02: 2706 1  (this was AFTER the firmware upgrade, ie, cr10x_firmware22.exe)
cr10x (jias), from *B, get:  02: 5931.0  (this was before the firmware upgrade, ie, cr10x_firmware22.exe)

* here is what the data were looking like from ucb (chan 202) at the end of the day:

* swapped second re-calibrated sonic (sn 0438) with the EOL sonic (sn
  0536) @ top of tower, SpB brought the EOL sonic back to NCAR.  Note that
  the csat that was originally at 2.5m (from 2004-2007) is now at 21.5m and
  vice versa.

* adjusted span gas flow rate

* swapped the broken ucb logger (cr23x micrologger) with one of Jia's cr10x 
  loggers; still couldn't get the logger to send the data to the data system 

* the following code should work for the cs616 water content reflectometer using
  instruction P138:

Wednesday, February 20, 2008 site visit:
--------------------------------------------------------------------------------
At the site: JB, NT

Purpose of visit: diagnose/fix the problem with the ucb logger/chan202 (data 
stopped coming through this channel around 1:40 UTC on 2/19, which would be 
around 18:40 MST on 2/18), i.e.

Also, to download from the uc logger and check on the new span and N2 cylinders

Weather: very warm, sunny, calm

Misc. notes: helped NT haul a piece of 4-by-6 plywood out to her snow exclusion
plot in the eastern forest

Drove to the Marr Lab with NT in the gray Jeep, hiked to C1

--------------------------------------------------------------------------------

* span @ 1750 psi (dropping 25 psi/week, seems good); N2 @ 1700 psi (dropping 
  ~200 psi/week, seems okay)

* downloaded from the UC logger

* downloaded from the UCB logger

* Opened the ucb logger box and saw that the logger's LCD was "blacked out."
  Fortunately, I was able to connect to it and download the data. There
  was no new data coming in though. Checked the power at the logger and saw only
  10.2 VDC. Before messing with the power I downloaded from the uc logger. 
  Power here seemed fine, at 12.8 VDC. Next I went over to the action packer
  with the batteries for these loggers and checked power there. The uc battery
  was outputting 13.75 VDC. The ucb battery was outputting only 11.5 VDC. I 
  noticed that the charger didn't look solidly plugged into the power strip so 
  I fixed this then re-tested the battery output. It was a few tenths higher. 
  I then disconnected the ucb logger from the battery and re-checked the battery
  output, which jumped to 13.5 VDC. It seemed to be taking a charge so I
  re-connected the ucb logger and re-checked the battery output, which showed 
  12 VDC...Still an increase over the last time I checked with the logger 
  connected, although there is obviously some drainage by having the logger 
  connected. Went back over to the loggers to check power and try connecting 
  again. Power and connection at uc were fine (i.e. nothing went hay wire when 
  I was tampering with the batteries). When I re-opened the ucb box I noticed 
  that the cells on the LCD had become much darker, just like the screen on the
  nctc logger a few months back. And this time I couldn't connect to it, 
  even after ten+ tries. 

  Seems like there is definitely something wrong with the logger (reminiscent 
  of the problem with the nctc logger back in October '07), but there could 
  also be something going on with the power.

Wednesday, February 13, 2008 site visit:
--------------------------------------------------------------------------------
At the site: JB

Purpose of visit: grab snow depths and data from the mrs, soil, tcs and noah
loggers; bring a suitcase of flasks back to campus; get pressure bomb equipment
for Mick; swap gas cylinders at the tower; continue work on Noah's snow sensors

Weather: beautiful day, unusually warm, mostly clear skies, some gusty wind at
times

Misc. notes: dug a huge hole in front of the trailer door, although it will
probably be filled in by next visit; on Sunday (2/10/08) the female moose and
her calf were spotted by Stan in the far eastern forest near Nicole's snow
fence plots (no duel ensued); noticed there was no extension wire for snow 
sensor #2, thus couldn't connect this sensor (the other snow sensors I've been 
working on have extensions coming from Noah's logger/multi-plexer, and this one
was also supposed to have one...)

Drove a Chevy Malibu to the Marr Lab, hiked to C1.

--------------------------------------------------------------------------------

* retired N2 cylinder CC125555 (~empty), started N2 cylinder CC193045 (1900 psi) 

* retired span cylinder CC18996 (~empty), started span cylinder CC199497 
  (~1775 psi)

* swapped pcmcia cards at the mrs logger 

* downloaded from the soil, tcs, and noah loggers 

* connected snow sensor #3 (this is the northern of the two locations in the big
  clearing just a few meters to the east of the north canopy tower)

* hauled a suitcase full of flasks back to campus to mail to Utah

* brought the pressure bomb's regulator, mag glass and stopper kit back to 
  campus for Mick

* leak check info for the new N2 and span cylinders at the tower:

  N2 leak check         Span leak check
  --------------        ---------------- 
  12:27 1900 psi        12:27 1775 psi 
  2:30  1900 psi        2:30  1775 psi

* snow depths:

            closest to tree = 72 cm
     TP101 461 middle probe = 90 cm
             farthest probe = 95 cm  

Thursday, February 7, 2008 site visit:
--------------------------------------------------------------------------------
At the site: JB

Pupose of visit: swap flasks at the west robot and make sure the change of fudgeday for 2008 was accepted by the logger without any trouble (it was); download
from Noah's logger; try to install all three of Noah's new snow sensors; check 
on the N2 and span at the tower.

Weather: pretty cold and snowing most of the day; despite the NOAA forecast
calling for wind gusts up to 85 MPH, I felt little wind while in the forest 
around the tower, although the hike up to C1 from the Marr Lab was very 
blustery.

Misc. notes: Only got one of three snow sensors connected. Tried using the butt connectors supplied and recommended by Noah to crimp his snow sensor wires...I 
don't think these worked very well. Should devise an alternate method. The butt connectors are very difficult to crimp. There might be a specific tool? 

The sensor I connected is located ~30 yards SW of the north canopy tower, next
to a tree bole near Jia's sap flow site.

Drove a Chevy Malibu to the Marr Lab, hiked to C1. 

--------------------------------------------------------------------------------

* N2 @ 200 psi, span @ 100 psi 

* swapped 4 flasks at west robot

* downloaded from Noah's logger

* connected one of Noah's snow sensors (next to a tree bole ~30 yards SW of the
  north canopy tower, "beneath-canopy", near Jia's sap flow site; not sure if it  is working properly) 

Friday, February 1, 2008 site visit:
----------------------------------------------------------------------
At the site: JB, SLS, NT

Purpose of visit: to switch the SDM setting on the re-deployed, re-calibrated 
c-sat3 (2m); to reinforce the flagging around the mini tower; investigate the
gmp343 probe (off scale on cockpit); check how the span and N2 cylinders at the 
tower are doing; get snow depths

Weather: not too bad, warmer and pretty calm

Misc. notes: When there are two or more sonics on the same logger, each has to
have a different SDM setting (on the mini tower, the sonic at 2.5m is set to 
SDM 4, and the sonic at the top of the mini tower is set to SDM 3); the gmp343
probe is wired into SE channel 24 on the UCB logger...

yellow wire -- channel 24 low

metal wire -- ground

pink wire -- +12V

gray wire -- ground

Drove the gray Jeep to the Marr Lab, and hiked to C1 from there

-----------------------------------------------------------------------

* switched the SDM setting on the re-calibrated sonic from 3 to 4; this got it 
  working fine

* reinforced the flagging around the mini tower

* power cylcled the gmp343 probe and got it back on scale in cockpit 

* span @ 200 psi; N2 @ 190 psi; retired the N2 (CC198536 @ 190 psi, started 
  N2 CC125555 @ 400 psi -- this was Jia's summer pressure bomb cylinder)

*now depth at the snow temperature probes:
         closest to tree = 70 cm
  TP101 461 middle probe = 80 cm
          farthest probe = 86 cm

  

   

Tuesday, January 29, 2008 site visit:
----------------------------------------------------------------------
At the site: JB, SpB

Purpose of visit: to re-deploy the re-calibrated sonic at 2 meters on the mini
tower and remove the sonic at 2 meters on the mini to send in for re-cal

Weather: BRUTAL; -20 C and peak wind gusts ~25 m/s

Misc. notes: SpB flagged off an area containing subterranean sensors around the mini tower...fortify this with rope/string next visit; JB and SpB helped 
Duane/Dwayne? load NT's snow blower onto the snow cat; didn't get the 
re-calibrated sonic working yet, need to change SDM settings... 

Drove the gray Jeep to the Marr Lab, hiked to C1 along the main road 

----------------------------------------------------------------------

* Snow depth at the snow temperature probes:
       closest to tree =  53 cm
TP101 461 middle probe =  70 cm
        farthest probe =  77 cm

* re-deployed the re-calibrated sonic sn0226 at 2 meters on the mini tower,
  removed the 2.5 meter sonic (sn 0438) to send back for re-cal 
 
* JB and SpB helped Duane/Dwayne? load NT's snow blower onto the snow cat 
  
* SpB flagged off an area containing subterranean sensors around the mini 
  tower...fortify this with rope/string next visit

Friday, January 25, 2008 site visit:
---------------------------------------------------
At the site: JB, NT

Purpose of visit: to haul some gas cylinders to/from the tower; check current
pressures of gas cylinders running at the tower; swap flasks at the west robot
and change the logger program to account for the correct fudge day; download 
from some loggers and swap pcmcia cards at the mrs logger; dig out lowest 
profiler inlets at the mini tower and dig out the uc and ucb logger boxes; grab snow depths

Weather: cold, some snow 

Misc. notes: lost part of an ultra-torr fitting for one of the flasks not 
currently in use...there weren't any spare parts in the robot (only spare 
o-rings)...need to get a few replacements to have on hand

Drove the gray Jeep (two Prius cars are booked through March, and Trans.
Services is not allowing their new Prius to go to the MRS) to the Marr Lab,
hiked to C1 from there

Nicole was at the trailer for a few hours to mess with her broken snow blower

----------------------------------------------------

* re-calibrated csat3 returned to CU 

* hauled new span cylinder (CC199497) to the tower 

* hauled old N2 cylinder (CC199706, 100 psi) to trailer

* current N2 @ 400 psi

* current span @ 250 psi

* swapped 4 flasks as west robot, changed logger program to account for correct   fudge day (now=5, previously=6) 

* downloaded from soil, tc, uc, ucb, and swapped pcmcia cards at mrs logger; all  data files given correct post-processing name and moved to 
  /data/projects/NIWOT/data_logger/

*  dug out the lowest profiler inlets at the mini tower and the uc/ucb logger 
   boxes

* snow depth at the snow temperature probes:
         closest to tree = 50 cm
  TP101 461 middle probe = 65 cm
          farthest probe = 72 cm

Monday, January 14, 2008 site visit:
---------------------------------------------------
At the site: JB, SpB

Purpose of visit: remove the 24m sonic anemometer to return to Campbell for its
first re-cal in a decade; swap it with a loaner sonic from EOL; download data
from the loggers; do a cal and some post-cals on new/old span cylinders; look
for a SC532(A) 9-pin Peripheral to RS232 converter box

Weather: calm and warm early; wind picked up during the afternoon

Misc. notes: did not download from the UC and UCB loggers, and did not swap
pcmcia cards at the mrs logger; the LI-6251 used for cals in the trailer was
acting flakey so we couldn't do the cals and post-cals we had hoped to do
(fortunately we have one new, calibrated span cylinder in the trailer awaiting
transportation to the tower)

Drove the purple Prius to the Marr Lab, hiked to C1 via the road so we could
drag EOL's sonic (in its caryying case) in a sled borrowed from the Marr Lab.
About half-way up the road Kurt ferried SpB and the sonic to C1 via his new 
wagon towed behind the snow mobile. 

---------------------------------------------------

* Snow depth at the snow temperature probes:
       closest to tree =   46 cm
TP101 461 middle probe =   63 cm
        farthest probe =   68 cm


* downloaded logger data from all loggers but UC and UCB (and did not swap
  pcmcia cards at the mrs logger).  data files are:

  than 4 cm/s.

* looked for a CS SC532(A)9-pin Peripheral to RS232 converter box in the trailer  but didn't find one

* SpB set up a CS 21x logger to test in the trailer (only outputting 
  battery voltage and reference temp and some junk)

* at around 13:30 MST, replaced the gelman filter on the 10m profile inlet.

Wednesday, January 9, 2008 site visit:
--------------------------------------
At the site: JB, SL

Purpose of visit: re-start west robot (which had been off during the holiday
season), grab snow depths, change span cylinders, swap desiccant at the 
LI-6251, swap 2-micron Nupro filters at the EC inlet, swap pcmcia cards at the
mrs logger. 

Weather: cold, breezy, snowing for part of the day

Misc. notes: encountered 2 moose, a large female and her calf, along the main
trail from the tower to C1. No male in sight. The mother and calf were pretty 
close to the bridge, and seemed to be heading in that very direction when I 
stumbled upon them (this is interesting because SpB photographed moose tracks
and scat near the bridge just a week earlier; maybe the moose like the willows
near the brige). I was dragging an old cylinder along the trail, not really 
paying attention to the surroundings, and I startled the mother, which caused 
her to move...and it was her movement that I caught from the corner of my left
eye. Had she not moved when I approached I never would have seen them. She was 
just a little bit off the main trail, her calf deeper in the woods, but when I 
startled her she moved deeper into the woods to position herself directly 
between me and her calf. They blended in with the trees so well. I hung out for a few minutes to observe them. They didn't seem too worked up by my presence. 
Eventually the mother must have stopped feeling threatened because she started 
moving north again and revealed her calf to me. The calf was pretty big too, 
but probably only half the size of the mother. In sum, they didn't seem 
aggressive, but it is probably worthwhile to be on the lookout for the male, 
who could be an aggressor. 

Drove the gray Jeep to the Marr Lab, hiked to C1
----------------------------------------

* Snow depth at the snow temperature probes:
        closest to tree = 44 cm
           middle probe = 61 cm
         farthest probe = 68 cm

* re-started the west robot, everything seemed fine

* swapped pcmcia cards at the mrs logger; dumped the data into the new 
  common data directory on russter2 (/data/projects/NIWOT/data_logger/)

* N2 cylinder at the tower @ 900 psi

* @ 1:32 MST, stopped the GAST pump at the base of the tower, swapped 2-micron
  Nupro filters at the inlet for the EC system, then re-started the GAST pump
  @ 1:53 MST

* changed the desiccant for the LI-6251 between 2:04 and 2:24 MST

* retired Scott-Marrin span cylinder CC66823 @ 150 psi (hauled it back to the 
  trailer), started Airgas span cylinder CC18996 @ 400 psi

Friday, January 4th, 2008 Visit:
--------------------------------
At the site: SpB, NT, SL

Purpose of visit: return russter2 to the trailer.

Weather: very windy.  But warm (for this time of year).

--------- Misc Notes:

* drove myself up, NT/SL rented a jeep from CU.

* Nicole and Stan were working out at their plots.

---------

* UnixOPS/Orrie were able to extract all the data from the old disk in
russter2 and put it on a new HD that i bought in Boulder.

* it wasn't clear if they were going to be able to finish this by the
end of the day, but they contacted me around 2pm and said it was
ready...so i had time to pick it up (with the new disk) and haul it
back up to the trailer.  plugged it back in at the trailer and it
worked.  The data system was running again at 16:30 MST.

* see "equipment purchases" for details about the western digital
EIDE hard disk.

Thursday, January 3rd, 2008 Visit:
----------------------------------
At the site: SpB

Purpose of visit: check on russter2, download logger data, and (maybe)
replace the motherboard.

Weather: overcast.  some wind bursts, but not too windy.  much warmer
than it has been recently.

--------- Misc Notes:

* rented a prius from CU.

---------

* Snow depth at the snow temperature probes:
       closest to tree =   38 cm
TP101 461 middle probe =   52 cm
        farthest probe =   58 cm

* tank pressures:

            N2 @ 1150 psi
          span @ 200 psi.

* when i arrived in the trailer russter2 had a frozen screen...it
looks like it locked up as Jia was trying to log out (her window was
still on the screen).  it rebooted just fine (had to reboot with the
power button).

* note, on russter2: the "outside world" network cable goes into the
LOWER NIC card (eth0) and the tower network cable goes in the UPPER
nic card (eth1).

* orrie started the backup process at around 10:45am.  i connected
russter2 directly to the outside world (ie, bypassing the D-Link hub
on the right-side of russter2).  it looks like these are the backup
processes:

root      4898  3.9  0.6  7140 1756 ?        S    10:48   1:14 sshd: root@notty
root      4908  0.0  0.3  5508 1008 ?        S    10:48   0:00 csh -c /usr/local/python/bin/rdiff-backup --server

* messages from the logs...

is this "abnormal status" normal??

At the site: JH, RJ

Jia went to the site...she rebooted russter2 which had apparaently crashed
the night before...ie:

-rw-rw-r--    1 root     aster    32252176 Jan  1 09:00 nwt080101.080000

-rw-rw-r--    1 root     aster    12255232 Jan  2 04:02 nwt080102.080000

the reboot worked, but for some reason the data system did not restart...i
get the following:

Hi,

I just got back from the site.  I restarted the computer.  It took a
while since it said that the computer was turned off suddenly.  After
rebooting, I could not log onto the internet.  In fact, t he computer
froze as I tried to do get on the internet and there was a weird
clicking coming from the computer.  I just left things on as is, since
after the computer rebooted it kept asking if I wanted to reconfigure
anything.  I figure since you are going up there tomorrow, Sean, you
could figure out.

Sorry I couldn't make the problem go away...

Saturday, December 29th, 2007 Visit:
------------------------------------
At the site: SpB, EL-T

Purpose of visit: check on russter2 and replace the motherboard.

Weather: very cold.  some wind bursts, but not too windy.  squeaky
snow.

--------- Misc Notes:

* met Erinn (from UnixOPS) at settlers and carpooled up in my jeep.

* two snowmobiles went zooming past the trailer while we were there.

---------

* russter2 started having problems on 12/20 at 23:16 MST.  we were
able to log into russter2, but then there were I/O errors doing the
simplest commands, etc.  The errors in the log look something like:

 Dec 30 14:40:53 russter2 kernel: hda: dma_timer_expiry: dma status == 0x21
 Dec 30 14:40:53 russter2 kernel: hda: error waiting for DMA
 Dec 30 14:40:53 russter2 kernel: hda: dma timeout retry: status=0xd0 { Busy }
 Dec 30 14:40:53 russter2 kernel: 
 Dec 30 14:40:53 russter2 kernel: hda: DMA disabled
 Dec 30 14:40:53 russter2 kernel: ide0: reset: success

* Rebooted russter2 and everything came back up just fine.  Erinn
swapped out the motherboard, but when we tried to reboot russter2 with
the re-furbished board and tried to boot nothing happened.  We could
not even get a prompt or start of the boot (the power button stayed
"amber").  After trying this, we went back to the original
motherboard...which is most likely why the above error messages are
still showing up on Dec 30.

* we started to go out to the tower, but it was quite cold and there
didn't seem to be too much to do there (mostly brush the snow off the
instruments, etc).

* here's an email with some of the details about the problem:

  Hi Sean,

  Something is seriously wrong:

  matrix:~ > ssh russter2
  jesse@russter2's password: 
  Last login: Fri Nov 11 08:49:30 2022 from , :/home/staff/oncley:/bin/tcsh

  Could not chdir to home directory /home/systems/jesse: No such file or directory

  So it prompted me for my password, which means it didn't find my
  authorized_keys file in my home directory. It says my last login was
  from ", :/home/staff/oncley:/bin/tcsh", which is a piece of the passwd
  file and not the lastlog, and then it failed to find my home directory.
  It's a good bet that there's a fair amount of data corruption on
  russter2. No telling if it's caused by a bad controller or a bad drive,
  but something is definitely bad.

  I can try to reboot russter2, but there's a good chance russter2 will
  not come back. That may or may not be a problem -- if it doesn't
  reboot, it won't be usable, but it really isn't usable at the moment
  either. 

  russter2 has hardware support from dell, so we can order parts (disk
  and maybe controller/motherboard) and go up there. The trick is going
  to be getting parts and getting in to the trailer this time of year.
  How much downtime can you have on russter2? It's likely going to take a
  day to get parts and a day up there to have any hope of fixing this,
  and we are /very/ short on staff until 2008.

site visit on Monday, Dec. 17 2007 (JB)

very windy, but not very cold

purpose of visit was to reboot/diagnose the trouble with russter2 (although this
was taken care of by Kurt Chowanski before I arrived at the trailer), check on 
the span and N2 cylinders at the tower (which were fine), and swap flasks/
download data at the west robot

* span @ 425 psi

* N2 @ 1700 psi

* swapped 4 flasks at west robot; 071213w.dat is on the Bowling web page

* rebooted russter2 ~1:15 pm MST for a minor OS upgrade; russter2 and the data
system came back without any trouble

* took a brief inventory of gas cylinders in the trailer; confirmed that 
"CC199497 Airgas 407.9 ppm cal_co2_070503.dat" and "SG9151924BAL Airgas 401.8 
ppm still needs cal" are both in the trailer; also, there is one new, full N2
cylinder in the trailer (this is new from summer '07, CC125575)

Thursday, December 13th, 2007 Visit:
------------------------------------
At the site: JB, SpB

Purpose of visit: check on profiler KNF pump.  download
logger data.  swap gas cylinders.

Weather: cold and calm.

--------- Misc Notes:

* drove up CU jeep.  hiked up the snowmobile trail.

---------

* Snow depth at the snow temperature probes:
       closest to tree =   30 cm
TP101 461 middle probe =   48 cm
        farthest probe =   52 cm

* from 12:30-13:15 MST, cleaned krypton optics (first time the q-tip
  was starting to wear-out...so re-did this with a new/better q-tip).

* changed the profiler pump; swapped the UNMP30 KNI (s/n 1/761551) for a new
  UNMP30 KNI (s/n 1/950199).  details:

  wiring:  pins 1 and 4, black wires (AC power)
           pin2 = ground wire (soldered to pump).

  - at 12:04 MST, shudown the prof sample pump.
  - at 13:06 MST, new pump installed and running.
  - at 13:15 MST, zeroed li-6251, at 0.009 mV.
                  set flow to ~13-15 "ball" units.

* hauled N2 cylinder CC198536 to the tower.

* swapped N2 cylinder CC125555 @ 400 psi with CC198536 @ 1750 psi

* swapped airgas span cylinder CC240435 @ 200 psi with Scott-Marrin, CC66823 @ ~450 psi
  (note, for a short while CC18996 at 400 psi was connected)...but at
  14:30 MST, went to CC66823.

* hauled CC240435 back to the trailer for a post-cal.

* when we swapped span cylinders we noticed a leak in the cal system, possibly
at the regulator or somewhere downstream of the regulator. Plan of attack for
next site visit is to replace the cal system's dekabon tubing, maybe fittings
and unions also, or at least check that they are tight.

* swapped pcmcia cards at the mrs logger

* downloaded logger data:

Sunday, December 9th, 2007 Visit:
---------------------------------
At the site: SpB

Purpose of visit: re-connect the csm1 pcmcia card storage module
and add a card.   brush snow off of everything.

Weather: There has been about a foot of new snow over the past few
days.  But this was a classic winter day---calm in boulder, but windy
and clear up in the mountains.  a few turns below barker res the wind
started blowing...lots of blowing snow at the site as the lower
brances of the trees were still loaded with snow.

--------- Misc Notes:

* drove up my jeep.  the road to MRS was unplowed (since last week?)
  and i was the first car/truck to drive up the road.

* as i was leaving MRS, a jeep was stuck in a hole near the turn-off
  to the peak-to-peak highway.  a truck was there getting ready to
  pull him out...

* there was quite a bit of snow on the tower(s)...brushed it off.

* saw a red fox (crushed) on the side of the road approaching
  nederland.

---------

* Snow depth at the snow temperature probes:
       closest to tree =   37 cm
TP101 461 middle probe =   55 cm
        farthest probe =   58 cm

* downloaded the mrs logger data:

-rwxr-xr-x  sburns   aster      190519 Dec  9 12:19 mrs12_9.dat*

* this file starts on day 340...so we lost about a weeks worth of
  data...the logger by itself is good for storing about 3 days worth
  of data...

   more mrs12_9.dat
   131,340,1905,-5.886,-5.895,-5.929,-5.931,
   131,340,1910,-5.887,-5.898,-5.929,-5.927,
   etc, etc...

* re-connected the csm1 card reader and added a card to it.  (for
  future reference, it would have been better to leave the other card
  in the reader rather than removing it!).

* the profiler sample pump (ie, the one in the box with the LI-6251)
  was not moving much air (the flow meter shows a level of around
  "5").  we usually want this to be "15"...and it's good if it's above
  "10".  there is a chance the flow level is low due to a leak in the
  system??...but i didn't see anything obvious.  and this pump has
  been running since 8 Aug 2006, so it's probably running out of
  life...i checked and there is a spare pump in the trailer (in the
  pump cupboard).  we also have a kit to replace some of the parts in
  the box with new pump...i have not used this before so i'm not sure
  how much that will improve the performance.  anyway, let's go ahead
  and order a new pump so we have a spare on hand...it's a KNF UNMP30
  KNI pump (115 VAC, 60Hz)...

   KNF phone: 609.890-8600
   KNF webpage:  www.knf.com

  this pump is squeezed into the box rather tightly...we'll probably
  need to remove the one there and then bring it back to the trailer
  to do the connections (unless we get some warm weather).  i probably
  have some notes about doing this somewhere...i'll look around on
  Monday.

* next visit we should replace both the span gas and the N2.  even if
  there is some N2 left let's go ahead and replace it...we should
  bring out another N2 cylinder (or is there a full one buried under
  the snow at the tower??)....it looks like on 11/16 you hauled out N2
  CC193045...is this the one standing up next to the one currently
  running?  Or, how many full N2 cylinders do we have out at the
  tower?  (i know there is one by como creek)...

Thursday, Nov 29, 2007 visit: JB, JH

cold and windy

drove aquamarine Jeep half-way up the road to C1

tower tasks:

* downloaded from the soil and tc loggers, swapped the pc card at the cr10_mrs 
  logger

* snow depths: facing north, l=9cm, middle=10cm, r=4cm

* swapped 4 flasks at the west robot

* checked on the span and N2 cylinders at the tower (span@350 psi, N2@850 psi)

* brushed snow off of quacker's box, the soil, tc, noah and mrs logger boxes, 
  and some other boxes on the cuff tower

* confirmed the Netgear switch is in the trailer

* checked the network cable connections for the tower network and the network to the world at russter2 

misc:

* Jia was collecting needle and phloem samples 

* map of hydra inlet (US1, US2, UN1, UN2) locations

Monday, November 19th, 2007 Visit:
----------------------------------
At the site: SpB, JB, NT, SL, MW, CW

Purpose of visit: re-install 25m prop-vane.  upload some
logger programs.

Weather: Clear blue skies and rather windy.  But very warm
temperatures for mid-November.  A cold front is headed our way (thus
the wind).

--------- Misc Notes:

* drove up the aquamarine CU jeep (to the trailer).

* the weekend of nov 18/19 noah re-installed his snow depth sensor
  network and dave bowling re-started the the undersnow TGA system.

* NT, SL, MW, and CW were at NT's plots digging trenches

---------

* from ~10-12 MST, swapped out the RM Young 09101 "SE" prop-vane at
25m.  note, that we are using the Voltage output so the J1 jumper can
be in either RMY NCAR or NMEA protocol (these setting are for serial
output).  For voltage output, the "J3" jumper should have the far
right pins open to set the output to be calibrated 0-5 VDC.

Here is some of the RM Young prop-vane wiring:

* from 13:30-13:45 MST, modified the orientation of the LI-7500 at 2m
(note, it can be oriented any way, but upright is the recommended way
since all wind directions are then ok, see manual).

* re-deployed the repaired CSM1 card reader module at the mrs logger

* at 12:35 MST, sent a new program to the PROF logger:

-rwxr-xr-x    1 sburns   aster       15561 Nov 19 09:11 prf_01.csi*

   changes:  - stopped saving of the 1-minute co2 LI-6251 data

             - also no more "sec" in output, ie:

              1: 0111     Day,Hour/Minute,Seconds (midnight = 0000)

              changed to:

              1: 110      Day,Hour/Minute (midnight = 0000)


* at 12:47 MST, sent a new program to the CNR logger:

-rwxr-xr-x    1 sburns   aster        9036 Nov 19 11:47 rad_03.csi*

   changes:  - stop saving the sw_net, lw_net, albedo, rad_net parameters.
             - no more "sec" in output

* found noahs new logger program on our laptop, ie,

-rwxr-xr-x    1 sburns   aster       28564 Nov 16 16:13 noah_m.csi*

and a data file he downloaded,

-rwxr-xr-x    1 sburns   aster        4330 Nov 18 12:01 noah11_18.dat*

but on russter2 the date/time is,

so, need to fix the time on the webcam...can use a ntp server..which
would be nice to do.

---> at 12:00 MST on 11/14, I reset the clock on the forestcam to be
in MST...so now i have:

which was taken around:  Wed Nov 14 11:55:49 MST 2007

(there may be a few minute descrepancy between the camera time and russter2 time).

Saturday, November 10th, 2007 Visit:
------------------------------------
At the site: SpB, NT, SL

Purpose of visit: check on the 2m Rnet sensor (again), install
FC6 on quacker2 (inspiron 7500).

Weather: very nice day for Nov 10th.  there were some bursts of wind
from time-to-time.  started spitting snow lightly as we left (but
the skies were blue).


--------- Misc Notes:

* Nicole drove her car up.  And then we walked the powerline.

* Nicole/Stan were digging trenches around Nicoles plots.

---------

* checked the serial number of the lower (4.6m) TRH sensor (TRH5).
  it's HMP35C #10091, s/n s0630018 (maybe s06300128?), LT# 415758

* quacker2 was sitting in the trailer waiting for disk2 to be
inserted.  did this and then finished the installtion of FC6.  Made
sure that I selected all the programming tools.  And also tried to
install ntp (which doesn't seem to be working).

on quacker:

 fgrep russ /etc/ntp.conf
 restrict russter mask 255.255.255.255 nomodify notrap noquery
 server russter

on quacker2:

 fgrep 10.0.0.4 /etc/ntp.conf
 server 0.10.0.0.4
 restrict 0.10.0.0.4 mask 255.255.255.255 nomodify notrap noquery

modified this file to be:

 fgrep 10.0.0 /etc/ntp.conf
 server 10.0.0.4
 restrict 10.0.0.4 mask 255.255.255.255 nomodify notrap noquery

* N2 cylinder at tower was at 200 psi.

* downloaded logger data:

-rwxr-xr-x    1 sburns   aster       40228 Nov 10 11:36 ucb11_10.dat*
-rwxr-xr-x    1 sburns   aster        1333 Nov 10 13:15 ucb11_10b.dat*
-rwxr-xr-x    1 sburns   aster      192769 Nov 10 13:35 soil11_10.dat*

* from 11:30-13:00 MST, repaired the 2m Rnet sensor (note: after
looking at the data a few days later it seems ok).  Removed the AMP
connector and replaced it with a small junction-type connector where
the wires can be screwed into terminal-type connectors.  Note, when i
held my hand over the top (or bottom) of the sensor it would react,
but no-where near as quickly as it was on Friday (which seems more
like what I expected).  Never determined what the problem was...but
we've lost around 10-days of data (see web calendar).

* on plumwood: moved the pc208w directory to be right off the C:\
drive...i've re-associated all the programs that needed to be changed
except the west robot program since i'm not sure which program is
currently associated with it (since you can't see the program name).
i was getting annoyed that i couldn't see the name of the program in
the "Associated Program File Name" box...so that's why i changed it
(hopefully you don't mind this change).  i also changed the default so
with explorer you see the extention name + the file details..if you
don't like these changes feel free to change them back.

* also, noticed the amp connected for the fan for TRH sensor #5 did
not have any tape or backing on the backside of the amp
connnector...this could potentially allow water to get down into the
leads and short out the power...i added tape to one side and then
arranged it so it is under the PVC fitting which houses the fan (to
give it some protection from water).

* also, on quacker2, tried to install emacs, but get some weird
messages and then it doesn't exist...ie:

Thursday, November 8th, 2007 Visit:
-----------------------------------
At the site: SpB, JB, JH, NT, SL

Purpose of visit: check on the 2m Rnet sensor, swap out the N2, do
some final checks of the sensors connected to the soil logger.

Weather: Awesome (for Nov 8th).  A bit blustery at times.  And in the
afternoon a howling wind storm hit the site...but generally clear blue
skies and pleasant.

--------- Misc Notes:

* drove up the CU grey jeep.  (jia made the res).

* Nicole/Stan drove up separately and left earlier than us.

* time changed from MDT to MST last weekend.

---------

* brought up the disks to re-install Fedora on the insp 7500.  (it
needed the software development packages on it).  note, we ran out
time to do the full install...it was taking too long to copy all the
info from disk1.  So, it's sitting there waiting for disk2 to be
installed...

* from 10:45-11:40 MST, messed around with the 2m Rnet sensor.
  swapped the "+" to "-" wires into the diff channel...it seemed to be
  working when i left (but it actually was NOT working, see logbook
  entry from Nov 10th).

* from 11:30-12:00 MST, swapped out the N2 cylinder.

* from 13:08-13:20 MST, did a "warming" test of the snow temp probes (data
  are saved in the file, "mrs11_8b.dat").

  - from 13:08-13:13 MST, warmed up level 4 on the Td (ie, tall) probe...
  - from 13:15-13:19 MST, warmed up level 3 on the short snowtemp probe.

* checked the location of the soil moisture probes (note, also did this on Oct 25, 2005):

* put out some new dessicant packs in all the logger boxes
that are on the ground.

* downloaded logger data:

Tuesday, October 30th, 2007 Visit:
---------------------------------
At the site: SpB, JB, JH, NT

Purpose of visit:  finish setup of thermocouples at the N Can tower, work
with 2m Rnet sensor.

Weather: Blustery and cool.  Significantly more snow had melted since
last Friday.  There is almost no snow left...however, a small system
passed through after we had departed the site and left a dusting of
fresh snow.

--------- Misc Notes:

* drove up in the CU white suburban (Nicole extended the rental and
needed to exchange the jeep to have some brake work done).

* Nicole/Jia were working on snow-fencing stuff...

---------

* at 9:30 MST, power-cycled the eol tram data system (per Steve
  Oncleys request).

* messed around more with the 2m Rnet sensor:

  old 2m Rnet sensor wiring scheme (up until today):

  white pin 1 7H
  brown pin 3 7L
  black pin 4 7G

  new wiring scheme as of today:

  orange pin 1 7H
  blue (white) pin 3 7L
  white (blue) pin 4 7G

* setup 9 more thermocouple sensors connected to the soil logger am25t
  multiplexer.  channels 17-22 were setup as a TC "intercomparison"
  since last Friday.  Today added channels 23,24,25 (which fills up
  the am25t).  details:

 * when i was checking the am25t, chan20 had a loose wire which i
   re-attached.  Also, reconnected chan21 since this was giving
   intermittent data.


* downloaded logger data (it was difficult to connect to the cr10
logger??):

Friday, October 26th, 2007 Visit:
---------------------------------
At the site: SpB, JB, SO

Purpose of visit:  setup some thermocouples at the N Can tower.  Check
on the MRS cr10 "wp" logger.  re-install the nctc 23x logger.

Weather: Warm and sunny.  Most of the snow in the trees has melted,
but there are still patches of snow around.

--------- Misc Notes:

* drove up in the CU grey jeep (Nicole extended the rental).

* steve oncley was out working on the tram line.

* there was still a fair amount of snow near the soil logger which
made it a bit difficult to find all the Ttcs and check them.

---------

* re-installed the repaired NCTC cr23x logger (according to the
  report, the "crystal in location Y17N was bad")

* dumped all the water out of the CR10 logger box (note, that the MRS
  cr10 is a cr10 "WP" logger (sn 18657) and the calibration date was
  from 1986!)...there was still some ice in there that was more
  difficult to remove.

* when we tried to connect to the logger a "can't connect to logger"
error occurred.  There was not much else to try at the logger to make
things work (it had power, but 5V was not coming out of the 5V
terminals).

* there was a solid-state relay (a CRYDOM D1D07) that might have
been damaged (but turns out it is ok).
   input = 3.5 - 32 VDC
   ouput = 100 VDC, 7A.

   (i don't fully understand the function of this relay since one
    of the output ends seems to be connected to the 5V terminal on
    the logger??).

* the action packer with the pressure sensors (and one short-haul
modem) was off and sitting on the ground...why did this happen?

* switched out the MRS cr10 logger for a spare cr10 that jia removed
from her site yesterday...so the timing was good.  with jia's cr10
connected things started working again.

* in the morning steve oncley installed his fiber-optic media
converter box in the quacker box.  In doing this the MET logger became
temporarily disconnected from the short-haul modem...and we lost about
3 hours of hi-rate data from the MET logger.  I screwed the short-haul
connector together which should stop this from happening again.

* we did a quick check of how much conduction is in the those green
snow temp probes (tried to save 1-hz data with mrs_02a.csi):

 - at 13:04 MST, jeff put his hand on Td_4 (4th level from the
   top of the long probe)

 - at 13:10 MST, jeff stopped having his hand there and moved it to
   the short probe (under the tree).  He put his hand at the 2nd
   sensor from the top on this probe.

 - at 13:22:20 MST, the original (30-min) program, mrs_02.csi, was
   sent back to the cr10 logger.

* note, the status light on the card storage module (CSM1) was a solid
red color.  (is it usually like this?).  If we have an extra storage
module we should bring it out just in case this one has a problem...

* added 6 thermocouples to the soil logger am25t mux.  these are
channels 17-22.  For now they are tied together for a
"intercomparison" before setting them up near the snowtemp probes
(which should be done next time).

* at the soil logger started using, "soil_02.csi".  Here we've stopped
saving the "tdr" data and only save the "h2o_soil" data...since there
is a polynomial relationship between these two there is no reason to
save both of them...also started saving all 25 channels of the am25t
mux...the main change in the program is at:

 44:  Average (P71)
  1: 15       Reps
  2: 1        Loc [ HFT_1     ]

 45:  Average (P71)
  1: 8        Reps
  2: 25       Loc [ TDRwat_1  ]

 46:  Average (P71)
  1: 3        Reps
  2: 42       Loc [ PanelTemp ]

 47:  Average (P71)
  1: 25       Reps
  2: 47       Loc [ Tc_1      ]


which used to be (in soil_01.csi):

 44:  Average (P71)
  1: 32       Reps
  2: 1        Loc [ HFT_1     ]

 45:  Average (P71)
  1: 3        Reps
  2: 42       Loc [ PanelTemp ]

 46:  Average (P71)
  1: 16       Reps
  2: 47       Loc [ Tc_1      ]


* checked the 21.5m csat and it seemed to be aligned ok (after
the strong winds of a few weeks ago).

To:      Sean.Burns@Colorado.EDU
From:    Jeffrey Mark Beauregard 
Subject: critical site updates from 10/24

Hi Sean.

1. I downloaded from the soil and tc loggers, and these data files are
in my h ome directory on russter2.

2. The N2 cylinder at the tower still has 400 psi of pressure, and the
 span cylinder at the tower still has 700 psi of pressure.

3. I set up the cr23x but wasn't able to actually start it up because
I didn't have the green power plug with me...this was still on campus
from when I brought it down the other week...but I have located it
here and will bring it up to the site on my n ext visit.

4. Jia was up on the top of the north canopy tower today and called me
over to "chec k something out"...Noah's data logger box was wide
open. It looked like it had been left open ever since it was last
visited. The whole thing was in bad shape...everyth ing was sitting in
a few inches of water and ice. I didn't know what to do about it,
because it seemed that tipping over the box to empty the water would
have been a ba d idea...plus the logger seemed to be sitting a bit
above the water. Not sure how th is happened. I am guessing that at
some point everything in the box was covered in s now, so there might
be water damage to stuff that is now dry. Our "cuff" SC32A that you
put in there was totally submerged in water, so I took this out, dried
it off an d brought it back to campus this afternoon. My plan is to
test it with one of the av ailable 21x loggers at some point to see if
it still works.

5. There isn't that much snow on the forest floor, and today was
pretty warm up ther e.

If you do decide to go up tomorrow instead of Friday and can possibly
call me let me know, that would be ideal because I might not be able
to check my e-mail at home to night...Otherwise I will plan on Friday.

Jeff

Hi Sean.

Right-o...this wasn't Noah's box then, sorry for the confusion. It was
the MRS logger box. Anyway, I assume we will meet at 8:30 tomorrow
morning in Ramaley?

Tuesday, October 16th, 2007 Visit:
---------------------------------
At the site: SpB, JB, NT, C, LL

Purpose of visit:  setup some thermocouples at the N Can tower (never
happened).

Weather: Colder than it has been.  About 5" of new snow on the ground
from the storm on Sunday.  The road was ok.

--------- Misc Notes:

* drove up in the CU grey jeep.

* Nicole/Charlie were putting up snow fencing down by her plots.

---------

* Jeff and I helped Lynette collect soil samples along the tram
line in the morning.  We also pulled out all of her soil moisture
and temperature probes.

* at ~13:45 MST, turned off the slow ozone sensor (TECO).

* at 13:40 MST, disconnected the KZ PAR-Lite sensor.

* there was a cylinder of zero air (CC153241) that was outside the
fence at the tower...this cylinder had around 1300 psi of pressure.
moved it inside the fence and put it on the pallete.

* brought down the empty cylinder of zero air that was at HYDRA (CC?).

* brought up a full cylinder of N2 (it's on the floor of the trailer).

* checked the snowprobes and tape marking the hts.

  tree = ok.
   mid = 3cm too high, ie, a 40cm reading is ACTUALLY 37cm.
   far = ok.

* left a spool of TC wire out by the N Canopy tower.


we visited the old hydra and TRAM site at Como Creek to remove LL's soil gear, 
and also visited cuff

Purpose of visit: help move tram.

Weather: Awesome Fall weather continues.

--------- Misc Notes:

* drove up in the CU grey jeep.

---------

* spent part of the morning moving Tram stuff from Como creek up to
near CUFF tower.

* at 12:45 MST, shutdown HYDRA for the year.  Packed it up and moved
it down to NCAR for the winter.  Note, on 10/10 all the inlets at
different heights on the tram towers were moved together for a mini
comparison.  There are data from the night of 10/11 and the morning of
10/12 to compare these.

* the final pressures of gas cylinders at HYDRA:

* the steps for re-starting the isff.colorado.edu data system (all
  done as root):

  /etc/rc3.d/S99isff start
  adamserver
  nc_server (don't think this matters)
  rtrun -r 5 serial_ingest -z  (probably not needed?)
  kill -HUP  (ingest process 1)
   something like:   aster    12415  0.0  0.5  4832 1528 pts/4    S    23:28   0:00 -tcsh -c /home/aster/bin/Linuxi686/ingest -z; /home/aster/projec
  kill -HUP  (ingest process 2)
  ingest (start ingest again).

then you should get something like:

* tried to connect with the NCAR TC 23x data logger.  Could not make
any kind of connection...tried to use the CSI Dev Config Utility...but
the following error would occur:

  Device Disconnected
  "Clock check with the data logger failed"

  11:04:10.35 Fault
  "Classic ::  CmdClockSet"

when we tried to do *B at the keypad we would get an error, "Mode 11".
The other * inputs seemed to work ok (for example, *5 showed the clock
was working ok).  we tried doing, "*AAAAA98765" to reset the logger
memory.  After waiting about 10 minutes the screen went "black"...ie,
all the small cubes on the panel showed up as dark areas.  And then we
couldn't do anything else with the logger.

* when we couldn't get anything to work with the cr23x we disconnected
all the thermocouples and removed it from the tower.  The wiring is:

              purple wire = High
                 red wire = Low
                    black = signal ground.

Tuesday, October 9th, 2007 Visit:
---------------------------------
At the site: SpB, JB, MP, NT, SO + NCAR Crew

Purpose of visit: add back the re-furbished prop-vane (16m).
Add KZ PAR-Lite sensor.

Weather: Absolutely beautiful.  Clear.  Warm.  Sunny.  Calm.

--------- Misc Notes:

* drove up in the CU grey jeep (rented for a week since we
are moving TRAM later this week).

* Steve Oncley was up here yesterday getting ready for the TRAM move.

---------

* there were two bugs (some kind of pine beetle?) stuck in the rain
  gauge sensor...removed them.

* in the morning (~9:30 MST) installed KZ PAR-LITE sensor:

Info about Kipp and Zonen PAR LITE sensor:
------------------------------------------
white wire = +
green wire = -
shield = GND.

* replaced the 2 micron Nupro filters for the LI-6262 (both at the
inlet and in the box).  details:

  at 11:17 MST, flipped the LI-6262 to manual and did zero.

   original:
   co2 at 89 mV  dial = 2.70
   h2o at 64 mV  dial = 1.90

   after:
   co2 at 0 mV  dial = 1.35
   h2o at 0 mV  dial = 0.80

  -- changed Nupro Filters ---

    h2o at 130 mV  (i think there is still a little room to zero?).

  at 11:55 MST, back to sample.

* checked the heights of some instruments on the CU tower:

         T4/RH4 = 10.4 m  (see email from jeff on 12 july 2007)
         T5/RH5 = 4.6 m
   2d ati sonic = 9.3 m
         P_baro = 12.0 m
"16m" prop-vane = 15.0 m

* note, to check Tref_A on TC logger...i did this and it seems that
this box must get some afternoon sun (which is why the reading was so
high when i was downloading the logger data).

* at HYDRA did a swap of the inlets (this is to help identify any
problems with internal leaks, etc).  The inlets swapped are:

at 9:30 MST, doing a cal.  Turned off the gast pump.

A1 <--> B1
A2 <--> B2
A3 <--> B3 (note, the nut for B3 (T4-L) was a little loose before the swap)
A5 <--> B5
B4 <--> B6
A7 <--> B7
A8 <--> B8
A9 <--> B9

at 10:00 MST, gast pump back on.

* also checked the timing of the valve switches versus my watch
time....
     HYDRA switches to S9 (B9) at 10:03:55 MST (by my watch time)
     HYDRA switches to Sx+D+S1 (A1) at 10:08:27 MST (by my watch time)

* at HYDRA, cylinder pressures: zero air at 100psi, 384ppm at 890 psi,
  417ppm at 100psi.

* downloaded logger data (no time problems):

At the site: SpB, JB, MP, NT, SL

Purpose of visit: move ati 2-d sonic from the
ground up to the tower (9m).

Weather: Clear.  Warm.  Sunny.  Calm.

--------- Misc Notes:

* drove up in the CU grey jeep.

---------

* started collecing data from the cr10 MRS snowprobes.  started using
mrs_02.csi which includes saving of the Tref data, ie:

-rwxr-xr-x    1 sburns   aster       13193 Oct  4 10:39 mrs_02.csi*

* moved cylinder CC18996 from outside the fence, next to the span
gas---this is the cylinder calibrated by Britt/Andy.  We should use
this cylinder next...it is probably at around 1100 psi??

* Jia's N2 cylinder (CC125555) has 1300 psi.

* moved the 2d ati SPAS/2Y ati sonic from the ground up to a height of
  9.3m on the tower.  notes before moving the sonic:

 - the small circle (which seemed to be a mark with a sharpie on our
   sonic) is the "u1" transducer pair and should point North.

 - with our setup on the ground the transducers with the dots were
   in the vertical direction while the other pair were horizontal
   (aligned approx along the 50-230 deg from North).

 - jeff and i tried to point this pair of transducers toward true north
   at 9.3m on the tower.

* finished the blow tests of the HYDRA inlets...the final results are:

Wednesday, September 26th, 2007 Visit:
-------------------------------------
At the site: SpB, JB, MP

Purpose of visit: add T/RH sensor #5.  change to winter
mode for fast logger.

Weather: An excellent fall day.  Chilly with a few wind gusts.  Nice
in the sun.  The Aspens have either dropped all their leaves or are
yellow.


--------- Misc Notes:

* drove up in the CU grey jeep.

* Jeff/Sierra were planning for a pre-dawn tomorrow morning.

* apparently a bow hunter that was near our towers had an "encounter"
with a Mt Lion sometime recently.  The lion did not run away
immediately and approached the hunter.

---------

* at ~10:00 MST, shutdown the fast ozone system.

* resent the tc_12.dld logger program to the TC logger...but it turns
out what i needed to do was redo the "association" with the logger
program (since the file structure of PC208W is different on plumwood
than the old gateway).

* at 11:00 MST, i reconnected power to the cr10 MRS logger..but I
didn't have a sc32a so i couldn't connect to the logger!!

* the tubing connecting the pressure sensor to the pressure port was
severed.  Probably just exposure and age.  Patched it up using one of
the tubing sections.

* checked the locations of the TCs connected to the am25t (sn 2283) and
  the soil logger:

     mux

   -------   ------------------------------------------------------------------
     1,      on ground ~ 50cm from AM25T box. (T-type tc, omega blue wire)
     2,      on ground, by one of middle snowprobes (T-type tc, campbell A3537).
     3,      ~1cm deep, between the two long snowprobes (T-type tc, campbell A3537).
     4,      ~1cm deep, near cs615 WCR probe #3 and temp probes (T-type tc, campbell A3537).
     5,      ~1cm deep, closer to tree than ch4 (T-type tc, campbell A3537).
     6,      ~2cm deep, near cs615 WCR probe #4 and near 35cm pit (A3537).

     13,     ~4cm deep, in clearing 6m SE of am25t box, just past ch12 (A3537). no photo
     14,     at 1.54m in tree, on the sunny side (omega blue wire).
     15,     at 1.54m in tree, on the shady side (A3537).
     16,     at -20cm, co-located with snowT probe (middle) (A3537).

Purpose of visit: finish setup of HYDRA data system.

Weather: Not bad at all.


--------- Misc Notes:

* drove up in the CU SUV.

* my stomach started hurting in the afternoon...

---------

* got some cylinders organized with Kurt, ie:

 Date:    Mon, 06 Aug 2007 14:49:29 MDT
 To:      "Kurt Chowanski" 
 cc:      Sean.Burns@Colorado.EDU
 From:    Jeffrey Mark Beauregard 
 Subject: your N2 cylinders

 Hi Kurt.

 I checked on those two N2 cylinders for you. They are both full. Here are the specifics:

 cylinder #CC198690    @2000psi
 cylinder #CC243067    @2000psi

 I chained these back up with the others in front of the trailer.

 Jeff

* re-started HYDRA.  started using two of the 6L cylinders, and a zero
air cylinder in the reference cell.  Found a leak in one of the 6L
cylinders (JJ16850) and are currently leak-checking the others.

* in the afternoon we played around some more with the webcam...we
were trying to make it possible to see the sky (and indian peaks) with
the webcam.  It worked, but it's tilted quite a bit (which seems
strange).

Friday, July 27th, 2007 Visit:
------------------------------
At the site: SpB, JB, RKM, RaM, RpM

Purpose of visit: finish setup of HYDRA data system.

Weather: It threatened rain several times.  Then at around 14:00-15:00
MDT it released a deluge.  We sprinted from the tram line back to the
trailer and were all drenched.


--------- Misc Notes:

* drove up in the CU jeep.

---------

* at 11:50 MST, started collecting co2 data with HYDRA.

* lineflow set to "40".  russ setup an inlet at the CU tower (0.5 or
  1m?) and it took around 5min for his puff of air to reach us.

Tuesday, July 25th, 2007 Visit:
-------------------------------
At the site: SpB, JB, LL, RKM, JS, AT, RaM

Purpose of visit: work on HYDRA data system.

Weather: Around noon it was hailing/raining fairly hard and everyone
was taking shelter.  This lasted for around 1/2-hr.  After this
everything was wet, but it didn't rain hard again...


--------- Misc Notes:

* rode up in the jeep.

* andrew was doing his sampling at the CU tower.

---------

* there was a problem with one of the fitting on the profile
system...which caused a large leak in the system (discovered during
the blow tests)...it seemed to start when the dessicant was being
changed so not a big problem.  however data during this day might be a
bit off...fixed it by re-doing the swagelok fitting on the small tube
that attaches to the dessicant tube.

* Russ and Jielun were setting up the inlets for HYDRA...here is the
  info:

 Subject: Re: inlets...

 Hi Sean,

 All inlets are ready to go, except the one that extends to the CU
 tower. There should be 15 currently (16 once we check the one to th e
 CU tower). The inlets should be labeled at the Hydra end and most are
 coiled and hung on trees near the Hydra. Here are the codes:

 U, Como 1 -- middle of Como Creek (short)
 U, Como 2 -- middle of Como Creek (long)
 U S 1 -- South of Como Creek (short)
 U S 2 -- South of Como Creek (long)
 U N 1 -- North of Como Creek (short)
 U N 2 -- North of Como Creek (long)
 T 1 U -- Tram tower 1 (upper)
 T 1 L -- Tram tower 1 (lower)
 T 4 U -- Tram tower 4 (upper)
 T 4 M -- Tram tower 4 (middle)
 T 4 L -- Tram tower 4 (lower)
 T 9 U -- Tram tower 9 (upper)
 T 9 L -- Tram tower 9 (lower)
 T 11 U -- Tram tower 11 (upper)
 T 11 L -- Tram tower 11 (lower)

 These are all ready for connection to Hydra. I'll be up on Friday and
 will check out the long line to the CU tower, then it will be r eady
 for hooking to Hydra by Friday midday.

 Thanks,

 Russ

Friday, July 20th, 2007 Visit:
------------------------------
At the site: SpB, JB, LL, RaM

Purpose of visit: work on HYDRA data system, shading for PAR sensor,
and 16m prop/vane.

Weather: It was quite humid (predicted 50% chance of t-storms that never
happened).  nice clouds, but no rain or thunder/lightning.


--------- Misc Notes:

* i took the MRS shuttle.  everyone else drove up in the Monson jeep.

---------

* after some consultation with Steve/Gordon was finally able to figure
out why the opto22 signal had a problem...the serial port (#2) on that
usb-to-serial converter that was supposed to send commands to the
opto22 was not working properly...switched to port3 and then it all
worked fine.  ARgh!!

* made some short synflex tubing lengths to connect to HYDRA during
the testing phase.

* adjusted the offset of the h2o.ec signal for the LI-6262 (noticed
that it was clipping on 7/19 since the signal was over 1100 mV).
details are:

  - at 10:14 MST, zero LI-6262

     h2o at +30mV, dial= 2.75
     co2 at +29.7mV, dial= 3.14

   new setting:

     h2o at -20mV, dial= 1.90
     co2 at  0mV, dial= 2.70

  - at 10:15 MSt, span gas.
  - at 10:16 MSt, back to sample.

* removed the PAR shadingband for some re-design work.

* removed the problematic 16m prop/vane and Kurt at MRS was nice
enough to agree to plug it in at the lab (i noticed he had a few
already there that he was testing).  [note, Kurt never did this since
ours is an older model!].

* logger data downloaded:

Purpose of visit: work on HYDRA data system, shading for PAR sensor,
and 16m prop/vane.

--------- Misc Notes:

*

---------

* moved the forestcam up to ~17m.

* at 9:23 MST, disonnected 2nd REBS from CNR logger and moved down to
2m at mini-tower.  The wiring is as follows:

AMP    wire
pin#   color   logger connection (channel=?)
----   -----   -----------------------------
1      white    H
3      brown    L
4      black    GND

* note that REBs output is hi-res (because this is what the pressure
  sensor was!)...also, the fan is not connected.

* at UCB logger started running ucb_08.csi (to output the REBs data
rather than the pressure data which had been there previously).
(note, pressure data are still saved in logger 5-min data files).

* tried to fix up the 16m propvane (replaced the cable)...but still
was showing negative voltages for WS.

* logger data downloaded:

Saturday, June 14th, 2007 Visit:
------------------------------
At the site: SpB

Purpose of visit:  work on HYDRA data system...

Weather: Five minutes after i arrived it started hailing.  And then it
rained on/off for the next 4 hours (or so)...some strong thunder and
lightning nearby...in the evening (when i was getting ready to leave)
it turned nice.

--------- Misc Notes:

* drove up the Monson jeep.

* since it was so rainy i spent some time getting caught up on the
  calendar page (photos, etc)...

---------

* determined that it's necessary to use a null modem when reading the
opto22 signal (sent from the quacker/adam) with hyperterm on a laptop
(ie, this is if you plug the serial cable that was going to the opto22
into the laptop)...

* based on this it seems that chan201 (ie, /dev/ttyUSB1) is NOT
sending out the commands...not sure why this is not working??

* was able to make it so that the adam/aster seems ok (though it runs
very, very slow)...cockpit was able to run ok too...ie:

  hi jeff,

  i recieved the following email from you about this:

   Date: Fri, 15 Jun 2007 11:45:19 -0600 (MDT)

   I forgot to mention this a second ago...Our edgeports were repaired,
   not replaced. They also did a nice job of cleaning them up on the
   outside. They almost look new...I have the repair reports (1 for each
   edgeport) and a shipping order. I will put these in the receipts
   binder.

  based on this it sounds like they might be in one of the receipts
  binders?  it would be good to have a record of which edgeport (ie, the
  serial number) is still broken.  I know it's the newer one, but not
  sure the serial number...though i might have that info somewhere.

 Cspan <- 397.6         #  cal cylinder is CC57787, (Airgas Value=396.0 ppm)
                        #  Trailer Cal=(397.98 + 397.04 +  397.33 + 397.87)./4=397.6
                        }

if(t1 >= utime("07 jun 22 140000"))     {
 Cspan <- 402.0         #  cal cylinder is CC240435, (Airgas Value=407.8 ppm)
                        #  Trailer Cal=(401.72 +  402.56 + 401.74)./3=402.0067 ppm
                        }

---------

* at 11:20 MST, krypton hygrometer was cleaned.

* continued to work on HYDRA with the ibm thinkpad (which doesn't have
ndaq, but uses the aster/adam sotware and the old code for controlling
the opto22).

* Kurt from MRS gave us a cylinder (CC193097) for the one he borrowed
from us earlier...ie:

 Hi Kurt,

 fyi---i found the cylinder (at least i'm pretty sure it's the one you
 are referring to)....it's cyl number CC193097.  i moved it away from
 the trailer so there is no confusion....i'm cc'ing Sean S so he can be
 aware of this too.

 thanks,

                                        SpB.

--------- Misc Notes:

* dropped the jeep off to get the flat tire repaired...they gave
  us a loaner.

* started gathering pipes, etc for mounting the forestcam on
 our tower.

* Sean Schaeffer was doing some laser stuff...

---------

* continued to work on HYDRA with the ibm thinkpad (which doesn't have
ndaq, but uses the aster/adam sotware and the old code for controlling
the opto22).

* i comppletely dismantled the LI-7000 box since i thought the pump
was failing...it turned out the inlet valve was closed..duh!

Monday, June 25th, 2007 Visit:
------------------------------
At the site: SpB, JB, LL

Purpose of visit:  connect new TRH sensor.

Weather: hot and dry!

--------- Misc Notes:

* CU jeep got a flat tire on the way up to the trailer.

* there were lots of power issues/problems the prev week (SpB was
  off).

---------

* moved the power for the profile pump up to a different circuit to
try and beter balance the power load.

* started to work on HYDRA which is near the trailer (using the dell
with linux on it, but there are a few problems with the aster/ndaq
data system on this laptop).


* a very rapid mixing event on the morning of 6/15/07...see the RH
sensor at 2m...and some upward pulses of T in the thermocouple
temperature data...and some associated downward pulses of wind.

* downloaded logger data:

-rwxr-xr-x    1 sburns   aster     1018007 Jun 25 10:54 soil6_25.dat*
-rwxr-xr-x    1 sburns   aster     1075142 Jun 25 10:43 tc6_25.dat*

retired span cylinder CC57787

span cylinder CC187116 had only 200 psi so I didn't use it (it was standing next to the above cylinder)

started span cylinder CC240435 (1900 psi)

Total power loss to C1 ~3:45 P.M. 

11:00 MST JB stopped ndaq

11:06 MST shutdown quacker

11:35 MST rebooted quacker with "CU Monson Lab" edgeport---quacker DID NOT
RECOGNIZE THIS EDGEPORT!

12:08 MST rebooted quacker with backup edgeport (not Gordon's) and everything
worked fine

(SpB and family showed up for a little while and SpB was around when quacker
would not recognize the first edgeport)

--------- Misc Notes:

* turned on the fans in the LI-COR boxes.

---------

* the snow depth at the snowtemp probes = 0cm.

* at 11:39 MST, connected new TRH sensor to MET logger...start running
"met_04.csi".

* started running ops43 to ingest new T/RH data (T4.met,RH4.met).

* at 13:45 MST, disconnected the MRS (snowT) logger from the power.

* replaced the battery in the soil cr23x logger.

* JB swapped the 6251 magnesium perchlorate trap and indicator tube
  Zero @ 12:59 MST = 0.005
  Zero @ 1:20 MST = 0.005

* Did a temporary "sealing" job on the asp. shield with duct tape

Monday, June 11th, 2007 Visit:
------------------------------
At the site: SpB, JB, JH, MP, SL1, SL2

Purpose of visit:  meet Mark W for LTER site review.

Weather: pleasant.  lots of Cu clouds floating around.  A few dark
periods with some very brief showers.  Lightning and Thunder as we
left the tower around 16:00 MDT.

--------- Misc Notes:

* the snow is really starting to go!!

* this was the LTER site review / poster session so didn't do any real
work!

* JB took forest phenol photos 9:30 MST

Friday, June 8th, 2007 Visit:
-----------------------------
At the site: SpB, JB, SL, NT

Purpose of visit:  swap flasks.  change out li-6262 pump.

Weather: cool in the morning.  but not too bad.  the previous day had
some seriously strong winds.  especially in boulder, but also up at
the tower.

--------- Misc Notes:

* the snow is really starting to go!!

* moved hydra back toward the trailer (didn't make it all the way
there).

---------

* Snow depth at the snow temperature probes:
       closest to tree =   0 cm
TP101 461 middle probe =   5 cm
        farthest probe =   2 cm

* switched the robot flask-sampling to summer mode (now running
  AUTO26NW.CSI).

* from 10:30-11:00 MST, swapped out the LI-6262 pump.

  - from 10:58-11:01, ran zero and span in the LI-6262.


* JB got robot pump working with MANUAL_6.DLD. Sent the new (summer 2007)
  AUTO26NW.DLD program to start summer mode sampling.

* JB downloaded 23xrad (CNR logger) data (CNR6_8.DAT)

* JB, SpB started moving hydra back to trailer

* SpB took forest phenol photo protocol pictures

* messed around some more with the 2-d ati sonic....created
some *.txt files from hyperterm,

 ati_1.txt = initial file
 ati_2.txt = blocking the vertical transducers...therefore,
   "u" is parallel to the ground.
 ati_3.txt = my hands are blocking the "u" axis.
 ati_4.txt = data with the "table" removed.
 at ~13:27, made another small adjustment...

* here are more details about the ati (from emails):

Date: Mon, 11 Jun 2007 09:43:18 -0600

Hi Sean,
The problem is probably that an echo, from U or V transducers is arriving
back at the correct timing to look like a directly received pulse. There is
a window of time that we look for received signals. It could be that this
timing ( and the amplitude of the echo ),is only correct at particular
speeds of sound or wavelengths.

I don't usually suggest that users decrease the sampling rate, but in your
case it might disrupt the timing of the received echo. With ticks per sample
set to 0, the sampling rate is 200Hz, once every 5ms. If we change the ticks
per sample to 1, we will sample at 100Hz, once every 10ms. If the
interfering echo is returning in about 5ms, it will no longer be in your
receive window. There still could be a bounce at 10ms, but the receive
amplitude of this bounce dies off exponentially with distance, ie time. This
setting will effect your output rate, from 10hz to 5hz. If you want to
maintain 10Hz, we can average fewer samples, samples per output should be
reduced from 20 to 10. The original sonic anemometrs we built sampled and
averaged at these rates, and Dr. Kaimal wrote his original paper on the
anti-aliasing filter achieved by block averaging with this in mind. So I
don't think you have any issues with a 5Hz Nyquist. If you reduce the
sampling rate any further and obviously if you reduce the output rate, you
might need to look at the effects of the frequency response on your data.

An anechoic material added to the structure could be attempted. I don't
really have any suggestions for you, some type of sound absorbing foam. This
might insulate your structure or disrupt the normal airflow, so I don't know
if it is practical or not.

Hi Gary,

it appears that it was indeed a "cross-talk" problem (because the
sonic was setup with a small table-like structure around it...after we
removed the table then the numbers became reasonable and it seemed to
work fine...is there something that can be done to avoid and/or
minimize the cross-talk?  I didn't notice this problem in the Fall
after i initially set things up...

thanks for any more thoughts about this (some of the current setting
on the sonic are shown below)!

Purpose of visit:  swap flasks.  change inlet filters.

Weather:  Still pretty cool in the morning.  Lots of Cu clouds
around.  It felt more like Nov than the last day of May.  Storms
coming off the divide.  Spitting snow from time to time.  When we
left it was nice and calm.

--------- Misc Notes:

* Kurt was messing around with ln2 and looking for a fresh N2
  cylinder.

* as i was leaving a pine squirrel came bolting out of the shed...and
  it had a baby pine-squirrel in its mouth/paws.  It seemed that it
  was trying to carry it to another location...

* installed a tool rack in the trailer...i think we need one for the shed
  too!

---------

* Snow depth at the snow temperature probes:
       closest to tree =  16 cm
TP101 461 middle probe =  40 cm
        farthest probe =  38 cm

* from ~11-15:30 MST, replaced the gelman inlet filters on the LI-6251
profile system.

* more work with the 2-d ati (previous day removed the mesh
surrounding it?)

  - at 11:04 MST, put a ziplock bag over the two heads that
    are parallel to the ground.

  - at 11:14 MST, switched the bag to go over the vertical
    heads.

* at 10:45 MST, started running "met_03.csi" where the 9m handar data
have been removed.

* from 10:52-12:30 MST, started running ops41 (removed handar.9m and
also modified the 2-d ati code).

* the wiring for the 9m handar:
  black = diff chan11 (H)
  green = diff chan11 (L) (w/ jumper to ground)

  white = ch12 (H?)
  black = ch12 (L?)

  black = +5V
  red = gnd.

* at 12:37 MST, started running ops42 (removed 2-d ati
and added back ncar TCs).

* downloaded logger data (time on the uc logger was off):

   closest to tree =   0 cm
       middle pole =  30 cm
     farthest pole =  34 cm

* messed around with the Fortress UPS in the trailer.  Pulled the
batteries out (LCV-12V33AP, Panasonic sealed rechargeable) and will
look into replacing them...

* also, played around with the 2-d ati sonic (see Jun 7 2007 logbook entry
  for more details).

  - aster/ndaq data system wants:
        8/N/1   (ie, 8 bits, No Parity, 1 stop bit)

  - ati default:  7/E/1

  - also, set "flow control" to NONE in the hyperterm settings.

* started messing around with the old shading band that was on the
side of the trailer (and looks like a home-ade job).

* from 11:30-12:30 MST, replaced the ec gast pump with a refurbished
pump.  made some flow adjustments to the LI-6262.

* at 11:50 MST, started running "met_02.csi" which outputs the RM
Young prop-vane data in mV (rather than using the calibrated output).

* downloaded logger data:

SpB's snow depths:
L=71cm
M=70.5cm
R=41cm

Span gas pressure and flow was "off" during LI-6262 calibrations...reset the 
span gas regulator's pressure back to 20 psi. Tank pressure at 500psi.

10:28 MST: span cylinder pressure = 500psi
           span regulator pressure = 25 psi 

10:31 MST: LI-6262 flow = 9.17sLpm
           CO2 mV ~1187
           H2O mV ~420

10:43 MST: adjusted span regulator pressure back to 20 psi

10:45 MST: LI-6262 back to auto; flow = 9.13 sLpm
           CO2 mV ~1195
           H2O mV ~400

Purpose of visit: fix the problems at the tower.

Weather: Very nice and clear in the morning.  BUT, it quickly clouded
up and felt like rain for a short time (with distant thunder).  Then,
it cleared up again.

--------- Misc Notes:

* bought a new netcom 5-port switch before heading up to the tower.  Note,
some of the ports on the old switch were still working!

 hi,

 fyi---they were out of stock on the 8-port switch...but they had a
 5-port switch available.  i bought that...the 8-port switch is still
 under warranty so we should be able to get a replacement (probably
 have to mail it in).  if we can't fit everything on the 5-port i'll
 leave off the pfp (since i thought this wasn't a critical thing to
 have on the network).  you should be back on-line about 1-2 hours...

 thanks,

* also, it appears that our "backup" edgeport didn't work..so we
borrowed one from Gordon/NCAR, ie:

 hey gordon,

 thanks...i've re-borrowed your edgeport...yes, i'll try to avoid the

 cabling (serial cables and/or network cables) that might protect
 against lightning strikes?

* at 11:00 MST, everthing back up and running.

* started ops40.  (which is the same as ops37).

* all extra short-haul modems are being stored in the green box by the
fence at the base of the tower.

* from 10:50-11:28 MST, replaced the 2-micron Nupro filter and the
dessicant tube in the LI-6251.

* note the fan for the aspirated T/RH sensors is:
   12VDC, 0.22 amps, 2410ML-04W-B40.

Saturday, May 19th, 2007 Visit:
-------------------------------
At the site: SpB, JB

Purpose of visit: a lightning strike hit near the tower.

Weather: it was overcast and cool.  There was a short time period when
it was raining.

--------- Misc Notes:

* somewhat of an "emergency" visit to the tower.

---------

* the GFI outlet at the tower had popped which is why there was no
access to the quacker (since this outlet powers the network switch).
Surprisingly, there was power on all the other circuits...and none of
the breakers at the base of the tower had popped.

* after a bit of trial and tribulation...started ops38.

Friday, May 18th, 2007 Visit:
-----------------------------
At the site: SpB, JB, JH, DK

Purpose of visit: swap cylinders at the tower.

Weather: warm and nice.  the snow is really starting to melt.  como
creek is starting to pick up steam.

--------- Misc Notes:

* Was able to drive to C1.

* as soon as i returned from the site there was a short power outage
at the tower (around 5-min long according to Duane).  This power
outage was long enough to kill the UPS attached to russter2.  So, i
drove back up and reset the UPS.  (it's not clear to me why the UPS
didn't automatically restart after the power was restored??).

---------

* Snow depth at the snow temperature probes:
       closest to tree =  50 cm
TP101 461 middle probe =  76 cm
        farthest probe =  80 cm

* snow depths at Ncan tower:

   closest to tree =  25 cm
       middle pole =  74 cm
     farthest pole =  77 cm

* between 10-? MST, replaced N2 at the tower.  Used cylinder CC198686
(at 2050 psi).

* brought up a N2 cylinder for Jia (CC12555).

* the fiber-to-copper ODS converter in the trailer is an "ODS 471".
Rx= Blue, Tx= Green. (not sure if this is at the trailer or quacker
end of the fiber?).

* for the GAST pumps, service kit is "K219".  they are supposed to run
between 10,000-18,000 hours before needing service.  The lifetime for
the pump bearing is around 27,000 hours (and it's not worth replacing
the bearing).

* at 15:20 MST, data system stopped due to power outage.

* at 16:30 MST, restarted UPS/russter2.

* it died later in the evening (between 20:50-21:02), but, happily, it
rebooted itself.

* for building ndaq (on jieluns old dell) do:

  cd /usr/local/ndaq/build/x86/
  ./configit.sh
  make
  make install

* also, to change the bootup on a dual boot linux system modify
  /etc/grub.conf

* when we tried to build aster it was missing the "rfid.c" file (which
  was something related to something steve oncley was doing?).

Thursday, May 10th, 2007 Visit:
------------------------------
At the site: SpB, JB

Purpose of visit: bring up some gas cylinders to the site.

Weather: fine.

--------- Misc Notes:

* Drove up the summer jeep.

* Was able to drive to C1 (there were several other people that drove
up to there).

* helped SO with tram for a few minutes just after we arrived.

---------

* Snow depth at the snow temperature probes:
       closest to tree =  80 cm
TP101 461 middle probe = 105 cm
        farthest probe = 110 cm

* snow depths at Ncan tower:

   closest to tree =  56 cm
       middle pole = 104 cm
     farthest pole = 103 cm

* hauled a cylinder out to the tower...but it was the cylinder from
  the post-cal!....so needed to bring it BACK to the trailer.  ugh!

* finally, completed the cable for the 2nd REBs sensor (sn Q96333).
Replaced the domes on this sensor and added it to the top of the tower
(this is for a comparison with the radiation sensors already up
there).  Note, we have only two more new REBs domes left..and no more
new gaskets.  There was a note on the REBs sensor...it was,

    "This unit removed from tower 10/15/02, B. Baugh."

* the wiring for the 2nd REBs sensor (4-pin amp connector):

     Pin 1 - red wire   -> +
     Pin 3 - black wire -> -
     Pin 4 - ground -----> Gnd

* moved around the N2 cylinders at the tower...positioned two new
cylinders inside the base of the tower...removed one near-empty one,
CC97976 (brought this back to the trailer)...and one with around 600
psi (CC176258) (left at the base of the tower).

* brought five cylinders back to campus (get the numbers).

* downloaded logger data:

Tuesday, May 8th, 2007 Visit:
-----------------------------
At the site: SpB, JB, NT

Purpose of visit: bring up some gas cylinders to the site.

Weather: Lots of fresh (wet) snow on the ground (and in the trees).
Bright and sunny.  The snow melted considerably while we were out at
the tower.  And someone was able to drive up to C1.

--------- Misc Notes:

* Drove up in the jeep (start of the summer rental).

* tried to make it up the road, but the new/fresh snow stopped us
  halfway up the steep part of the road (past the 2nd gate).

* nicole was making some measurements down near her plots. (she met us
  at MRS).

* the MRS snow survey started today.

* took down two natural radiaion shields that have been on the tower
  forever (and never been used as long as i've been here).

---------

* Snow depth at the snow temperature probes:
       closest to tree =  80 cm
TP101 461 middle probe = 112 cm
        farthest probe = 118 cm

* snow depths at Ncan tower:

   closest to tree =  60 cm
       middle pole = 111 cm
     farthest pole = 112 cm

* hauled the following cylinders out to the tower:
  N2:  CC125555  and co2/air:  CC240435

* from 12:30-12:45 MST, swapped out the REBs domes.

* re-aligned the direction of the rm young prop-vane at 25m.

* replaced the rm young propvane at 16m with the "spare" prop-vane (it
  had "26m" in tape written on it).  The old 16m prop-vane did not seem to
  be working so we brought it back to campus (not sure what the problem
  is).  (note: The spare prop-vane that was added to the tower seems to
  be giving negative wind speeds..but only part of the time??).  need to
  check into this in more detail....

that were at the top of the tower.

* from 11:15-11:50 MST, played around with the LI-6262 and LI-6251
flow rates for the N2 and span gas.

  @ at 11:15 MST, switched li6262 to "calibrate"

-------------------------------
At the site: SpB, JB

Purpose of visit: Check as to why the span tank cals had stopped
working (ec.Ftot was dropping way off during the span cal).

Weather: Very nice and calm and sunny in the morning.  The clouds were
building quickly in the morning and it was overcast by noon.  Snow was
starting to fall as we left.

--------- Misc Notes:

* Drove up my jeep.

* kurt showed me the webcam (old tundracam).  it's a Canon VB-C10R.

---------

* Snow depth at the snow temperature probes:
       closest to tree = 80 cm
TP101 461 middle probe = 108 cm
        farthest probe = 113 cm

* snow depths at Ncan tower:

   closest to tree = 80 cm
       middle pole = 109 cm
     farthest pole = 108 cm

* Snow depth at the snow temperature probes on April 19 (from Jeff):
       closest to tree = top of sensor
TP101 461 middle probe = 109 cm
        farthest probe = 115 cm

* at the tower the span tank regulator was at ZERO psi (on the line
side of the regulator).  For some reason the regulator was not working
properly...

* from 8:40-9:00 MST, reset the span tank regulator & tested the span
  calibrations.  played around a bit with the LI-6262 settings.

* at 9:07 MSt, slight decrease in the flow rate of li-6251.
  at 9:08 MST, switched profiler (li-6251) to span gas.
  at 9:09 MST, back to auto.

* sent a new program to the met logger:

-rwxr-xr-x    1 sburns   aster        9838 Apr 23 09:45 met_01.csi*

this program is supposed to close the valves on the span/N2 tanks in
case the power goes out at the tower and the logger resets itself.
Note, i forgot to download the logger data on the logger before
sending the program!

Tuesday, April 17th, 2007 Visit:
-------------------------------
At the site: SpB, JB

Purpose of visit: download logger data.  swap flasks.  figure out the
wiring for the 2nd REBs sensor.  Swap dessicant in profiler.

Weather: A mixed bag.  Sometimes the sun would come out and sometimes
it would be snowing ice pellets (usually whenever the laptop was
open).  Calm winds.  Very wet.  It snowed about 2-3" overnight...lots
of wet snow everywhere.  And water dripping off all the trees.  Below
the wet surface snow, the underlying snow was firm and well-packed.

--------- Misc Notes:

* Drove up a CU prius.

* Lots of yellow snow. (in the drip line of the trees).

---------

* Snow depth at the snow temperature probes:

       closest to tree = top
TP101 461 middle probe = 112 cm
        farthest probe = 118 cm

* snow depths at Ncan tower:

   closest to tree =   79 cm
       middle pole =  110 cm
     farthest pole =  110 cm


* tried connecting the 2nd REBs to the CNR logger (ch12 which used to
be one of the photodiodes).  could not find a combination of wires
that made the voltage positive?!?...there were 3 wires (one for
ground).

Saturday, April 14th, 2007 Visit:
---------------------------------
At the site: SpB

Purpose of visit: check on the status of the LI-6262 (the span gas
during cals seems strange).

Weather: Clear and windy in the morning.  The winds calmed a bit as I
was leaving.  There was a layer of fresh snow that was wet and heavy
on top of the older snow.  There were also some strange lines in the
snow (maybe from wind?).

--------- Misc Notes:

* Drove up my Jeep.

* grabbed 13m of 6-wire cable for the T/RH probe.

* brought back down some drierite that needs to be baked.

---------

* from 11:50-12:20 MST, fiddled with the valve on the span gas
regulator---the line-pressure from the regulator seemed fine (around
20 psi).  So maybe the valve was partially closed??  (Anyway, it seems
ok now).

* Snow depth at the snow temperature probes:
       closest to tree = 80 cm
TP101 461 middle probe = 108 cm
        farthest probe = 113 cm

* snow depths at Ncan tower:

   closest to tree = 80 cm
       middle pole = 109 cm
     farthest pole = 108 cm

* checked the wiring on the HMP35C:

also, the wiring for the HMP35C probe goes something like (this
assumes the wiring on the probe in the lab is the same as the one
connected to the tc23x logger..and i believe that is true):

   blue wire -> excitation port (in the example program i sent i'm using
                              excitation port 2).
    red wire -> +12V.
  black wire -> ground
  white wire -> single ended measurement (for Temperature)
 yellow wire -> S.E. measurement for Humidity
 green wire and bare --> ground  (though i think the green wire goes
   to nothing).

Weather: windy and blustery most of the day.  the wind calmed down
toward the end of the day.  The snow is really starting to melt...the
power line is about 1/2 snow-free.  And the snow-levels at the tower
are starting to come down.

--------- Misc Notes:

* Drove up CU compact.

 Date:    Thu, 22 Mar 2007 16:42:21 MDT

 Subject: new battery/charger/adapter for Niwot Ridge

 Hi Noah.

 This afternoon I replaced the fried equipment at your cr10x. I
 replaced everything: A/C adapter, battery, and the charger box (the
 old one was totally fried). Everything seems to be running smoothly
 now. I will plan on keeping the second new battery in our trailer at
 the site in case we need a spare in the future. If you have other
 plans for this extra battery (e.g. want it back) just let me know.

 Thanks.

 Jeff

Sunday, March 4th, 2007 Visit:
------------------------------
At the site: SpB, DL

Purpose of visit: Check on the profiler pump (that draws air
in the from the inlets).

Weather: Very calm in the morning.  And warm and sunny.  A few
wind gusts later in the afternoon.

--------- Misc Notes:

* Drove up my own jeep.

* there were 3 people looking for a lost cattle dog (jaydee?) that was
apparently found later. . .

* Don and I skiied west of the tower.  big trees.  and heavy (wet)
snow.  Snowmelt water was dripping off the trees.

---------

* at around 10:40 MST, switched on/off the pump.  At first i thought
it was pumping air in the wrong direction...but, after i turned it
back on it was definitely sucking the right way.  However still not
seeing LARGE co2 values from the lowest inlet.  the zero of the
LI-6251 seemed fine.  this is puzzling....might be an ice blockage in
the tubing??

* Snow depth at the snow temperature probes:
       closest to tree =  (buried)
TP101 461 middle probe =  121 cm
        farthest probe =  128 cm

Weather: very cold (from what i hear).

--------- Misc Notes:

* Drove up a CU Jeep rental.

---------

* at 5:08am the quacker crashed (probably because it was very cold).
Jeff went up and switched everything back to one edgeport (started
ops36).

* Snow depth at the snow temperature probes:
       closest to tree =  (buried)
TP101 461 middle probe =  125 cm
        farthest probe =  131 cm

Purpose of visit: Download logger data.  swap robot flasks, re-install
the krypton hygrometer.

Weather: Not a cloud in the sky (well maybe a few off in the
distance).  Very clear up near the divide.  Smog/Haze out in the
plains.  A few gusts of wind, but overall quite calm and nice...not
bad for Feb (temp probably in the 40s).

--------- Misc Notes:

* Drove up a CU rental.

* duane was pumping gas.


---------

* Snow depth at NCanopy Tower:
       closest to tree =  80 cm
                middle =  98 cm
                   far =  107 cm

* Snow depth at the snow temperature probes:
       closest to tree =  (almost buried)  cm
TP101 461 middle probe =  103 cm
        farthest probe =  110 cm

* from 12:30-12:50 MST, re-installed the kyrpton hygrometer (according
to campbell there will be more detector tubes available in the
future).  The voltage was over 5V so it was being clipped by the
cr23x.  (it's below 5V as of Monday, Feb 26).

* started ops35 (went back to using 2 edgeports)...on Friday, noticed
a problem in the channel_config file where i had started using:

  quacker            iv1624  0       211     0       on      obsolete        9600.8.8.1      cr10_6x         # for tc23x logger

which should have been:

  quacker            iv1624  0       211     0       on      obsolete        9600.8.8.1      camp_21x_4      # for cr21x logger (ascii)

* at the soil logger checked the channels and the
cables:

       cs616 #2 --> chan 12
       cs616 #1 --> chan 11  (very tight...loosened the
                                 cs616 cable a bit)

* tried to download noahs snow depth data...the battery was dead (but
i think it was the ac adapter that was the problem).  emailed noah to
find out what he wants to do about this.  here are some of the specs
on his a/c adapter:    input - AC 120V  60Hz  30W
                       output - AC 18V  1.11A
                 name= Tamara class 2, s/n 830A0064-03

* swapped 4 flasks at the west robot.

Purpose of visit: Download logger data.  swap robot flasks.

Weather: Some low-level fog down on the plains.  Sunny in the mountains
on the way up.  But cloudy/overcast/blustery near the tower.  Started
snowing at the trailer as we were leaving.

--------- Misc Notes:

* Drove up a CU compact.  Met at noon at NCAR and drove up from there.

* bumped into Dean Anderson on the way out to the tower.

* Dave Bowling et al. have been working on the laser this week.  He
was in the shed doing some programming stuff while we were up there...

---------

* Snow depth at NCanopy Tower:
       closest to tree =   70 cm
                middle =   90 cm
                   far =   90 cm

* Snow depth at the snow temperature probes:
       closest to tree =   78 cm
TP101 461 middle probe =   95 cm
        farthest probe =   103 cm

* hauled two N2 cylinders out to the tower:
  CC153484 - new
  CC176258 - at 600 psi (i think this was used by Jia last summer).

* brought back two empty N2 cylinders...one was CC199718 (150 psi)
  and the other was CC140765.

* from 13:52 - 14:05 MST, swapped out the dessicant on the profiler (li-6251).
    - at 13:52 MST, did zero (value is approx -0.014 mV).
    - at 14:02,  did zero + blow test (ok).
                (zero is approx -0.005 mV).
    - at 14:05,  back to auto mode.  flow rate at ~18.

Purpose of visit: Download logger data.  swap robot flasks.

Weather: Excellent working day for January.  Clear blue skies.  An
upslope wind blowing for most of the day.  Warm and pleasant.

--------- Misc Notes:

* Drove up a CU prius.  (it was the purple one, and the trunk would
not close very well).

* heard (and saw) lots of snowmobiles.  when i was at the N canopy
tower someone (dave millar) drove out and (probably) filled the laser
with ln2.  there was also a cylinder sitting along the trail (near
como creek).

* there was signs of digging up cylinders out near the shed.  (i
warned them not to leave them lying flat on the ground before the
snow came!)

---------

* Snow depth at NCanopy Tower:
       closest to tree =  70 cm
                middle =  92 cm
                   far =  90 cm

* Snow depth at the snow temperature probes:
       closest to tree =  78 cm
TP101 461 middle probe =  98 cm
        farthest probe = 102 cm

* Carried out a few parts for steve oncley for the tram line.  (tram
is starting to come together).

* from 12:15-12:40 MST, tightened the CNR-1 net radiometer.  (it was
ok, but we added a couple of self-locking nuts just to make sure).

* re-aligned the REBs Rnet sensor.  it was obviously blown a bit
out of alignment (not sure when that happened).

* swapped out N2 at the tower:
     old cylinder:   CC199718  at around 150~psi.
     new cylinder:    CC97976  at around 1950 psi.

* from 15:50-16:20 MST, replaced the 2 micron Nupro filters---at the
inlet and the one in the li-6262 box.  At around 16:20 MST, back to
sample.  Did a slight adjustment to the zero offset of the li-6262.

---------------------------------
At the site: SpB, JB

Purpose of visit: Reboot quacker.  Swap west robot flasks.

Weather: Calm in the morning.  Then there were a few wind
gusts. . .then it started blowing more and more.  Fog down in Boulder
early in the morning (still some remnants visible around 10am from
MRS).  It's been very, very windy over the past several days (lots of
needles, cones, etc on top of the snow).

--------- Misc Notes:

* Drove up a CU prius.

* Data system crashed due to a power outage at the MRS on
Monday morning (data system stopped around 6am MST).

* Dean Anderson was paying a visit to the USGS tower.

---------

* Had to dig out the trailer door.  The road was blown out, but the
snow was piled up along the edge of the trees.

* at 11:50 MST, the quacker rebooted and seemed ok.  looking at the
logs it never completely crashed, but went into "suspend" mode.

* from 12:15-14:00 MST, changed out the span tank at the tower.
  old cylinder:  Airgas/CC187116 at 150 psi.
  new cylinder:  Airgas/CC57787 at 1800 psi (nominal conc 396 ppm)

* from 14:06-14:07 MST, ran N2 and span through the li-6262 (to adjust
the span tank regulator).

* Snow depth at NCanopy Tower:
       closest to tree =  75 cm
                middle = 100 cm
                   far =  95 cm

* Snow depth at the snow temperature probes:
       closest to tree =  80 cm
TP101 461 middle probe = 102 cm
        farthest probe = 108 cm

* swapped 4 flasks at the west robot.  according to Andy there
is no longer a problem with flask #14 (Andy noticed a leak there
a few weeks ago).  Jeff also uploaded the new logger program,

Weather: It was warm and pleasant.  There were a few wind gusts during
the morning.  As I left it was starting to blow pretty hard and snow
was blowing around.


--------- Misc Notes:

* Drove up a CU prius.

* Happy New Year!

* a few BIG snowstorms since my last visit.

* someone had snowshoed out to the tower (they went into the bowling
shed).

* David Millar must have stopped by sometime while I was up there
(though i never heard him).  Fresh snowmobile tracks were there on my
way back.

---------

* Had to dig out the trailer door---not too bad (it looked like
someone else had dug out the trailer after the big December storm).
Snow on the tower was not too bad.  The lowest few levels (at N Canopy
tower too) still had quite a bit piled up.

* Snow depth at NCanopy Tower:
       closest to tree = 70 cm
                middle = 85 cm
                   far = 85 cm

* Snow depth at the snow temperature probes:
       closest to tree = 70 cm
TP101 461 middle probe = 89 cm
        farthest probe = 95 cm

* note, at 14:10 MST, the tree snow temp probe is in the sun! (see
photos).

* reset (almost) all the logger times (based on my watch time which
was synchronized with russter2).  nctc logger was around 1.5 minutes
SLOW.  downloaded logger data:

At the site: SpB

Purpose of visit: Download logger data.  Swap robot flasks.

Weather: A great day for mid-December. . .fairly calm and warm-ish.  A
cold front was coming and the temperature was dropping over the time i
was at the site (from around 11-3pm).  An upslope wind was blowing at
the tower.


--------- Misc Notes:

* Drove my own jeep up.

* I heard a snowmobile (David Millar) while i was out at the west
robot.  The tracks showed that he stopped by to service the laser.

* Snow depth at NCanopy Tower:
       closest to tree =   26 cm
                middle =   40 cm
                   far =   40 cm

* Snow depth at the snow temperature probes:
       closest to tree =   30 cm
TP101 461 middle probe =   46 cm
        farthest probe =   49 cm

* from 13:06 - 13:20 MST, swapped out the dessicant on the profiler (li-6251).
    - at 13:06 MST, did zero (value is approx -0.012 mV).
    - at 13:17,  did zero + blow test (ok).
                (zero is approx -0.008 mV).
    - at 13:18,  ran span into li-6251.   (value is approx 1.368 mV).
    - at 13:20,  back to auto mode.  flow rate at ~18.

At the site: SpB, SO, C

Purpose of visit: Download all logger data (after the data
system crash).  Change out the N2 cylinder.

Weather: Windy, but nice in the trees.  Not a bad day for
December. . .was even able to sneak in a trip up to the top of the
tower to grab some data (the wind picked up at various times
throughout the day).

--------- Misc Notes:

* Rented a prius from CU.

* copied down all the power info from the book in the green
trailer.

* Steve O had rented the snowcat to haul up a bunch of tower-related
stuff.

* wanted to check o-rings on flask 14 at the west robot--never had
time to do this.

* Snow depth at NCanopy Tower:
       closest to tree =  30 cm
                middle =  47 cm
                   far =  46 cm

* Snow depth at the snow temperature probes:
       closest to tree =  34 cm
TP101 461 middle probe =  50 cm
        farthest probe =  53 cm

* between 10:30-11:05 MST, swapped out the N2 cylinder.
New cylinder = CC199718 at 1850 psi.
Old cylinder = CC140765 at 100 psi.

* at 11:09 MST, re-zeroed the li-6262.  it was:
   co2 at -235 mV
   h2o at 2.75 mV  (dial = 3.8?)

   changed to:

   co2 at ~0 mV
   h2o at ~0 mV

  at 11:13 MST, back to sample.

* downloaded logger data:
