1JD32Site Visit (JB, SLS, NT): Details 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) see details for snow depths SpB Off |

7JD38Site Visit (JB): Details N2 @ 200 psi, span @ 100 psi swapped 4 flasks at west robot downloaded from Noah's logger set up one of Noah's snow sensors (next to a tree bole, "beneath-canopy", near Jia's sap flow site ~30 yards SW of the north canopy tower; not sure if it is working properly) SpB returns |

13JD44 (beautiful, warm day, though gusty at times)Site Visit (JB): Details 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 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 see details for snow depth and leak check info |

18JD49at 18:40 MST, UCB logger (chan 202) stops output 1-hz data. |

20JD51 (very warm, sunny, calm)Site Visit (JB, NT): Details span @ 1750 psi (dropping 25 psi/week, seems good); N2 @ 1700 psi (dropping ~200 psi/week, seems okay) downloaded from the UC logger tried to diagnose the problem with channel 202/ucb logger see details for info on UCB logger |
21JD52 (cold and snowing)Site Visit (JB, SpB): Details , Photos (9) Details swapped 4 flasks downloaded from noah's logger swapped second re-calibrated CSAT3 sonic (sn 0438) with the EOL sonic (sn 0536) @ top of tower (SpB brought the EOL sonic back to NCAR) adjusted span gas flow rate swapped the broken ucb logger (cr23x micrologger) with one of Jia's cr10x loggers see details about this logger swap |
22JD53 (warm, sunny, mostly calm)Site Visit (JB, JH, NT, SLS): Details 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 |
