from 10:00-10:15 MST, removed screens from OTT Pluvio sensors (tested them w/o screens and now they seem ok)

NOTE: do not use pluvio1/pluvio2 data since Tue 6/25/24!

from 11:30-12:00 MST, added span (ru000402, from LBL) and n2 gas cylinders (cc236580) to the ap200 system

from 12:30-13:00 MST, moved ap200 temp sensor #8 from ap200 level to 21.5m

at around 3:30 MST, there was a large power outage that affected Ned to Ward (and MRS)

at around 13:00 MST, the power was restored

the fast logger did not come back up (NCTC logger is also dropping many samples)

at 15:45 MST, did ddn/dup to the nidas system to try and fix any issues (didn't seem to help)

[p.s. about five min after ddn/dup, the fast logger DID start sending data...NCTC is still having some issues]

[p.p.s., Dave from MRS reported that a marmot had gotten into a transformer box...and shorted some wires (and itself)]

at 23:51 MST, the fast logger (ch. 30) stopped working again!

Very Hot

changed the power source for the fast logger (now the fast channel is ok)

DB added four meter teros11 tree water content sensors near the N Canopy tower

at 11:30 MST, reduced the span/n2 cylinder pressures for the AP200 (to match flow/pressure during inlet sampling)

from 9:45-9:47 MST, added 500 ml of water to pluvio2

from 10:14-10:25 MST swapped the 21.5m LI-7200 inlet (added the heated inlet, set to 2 Watts)

at around 12 MST, swapped SD card from GPSCAM

from 12:40-12:45 MST, swapped the location of pluvio1 with pluvio2 (and started using ucb_33.csi; consistent saving of pluvio1/2 variables)

both tree sway sensors had no data (dead battery?)

from 14:00-15:00 MST, moved ap200 temp sensors to new locations: #8 (21.5m), #7, #4, #5, #6, #3, #2, #1 (20 cm)

Just-before we left, we decided to turn off the LI-6262 GAST pump
