Dec 6, 15:20 pm
Removed TRH023 which has been reporting raw values of 0 for T and RH since yesterday. Saw no obvious problems with the transducer.
Installed TRH24 at 15:30
Sonic has wicks.
Pulled a drip loop in downlooking PYG cable. PSP had a nice drip loop.
Dec 6, 14:20 Tom, Gordon
Installed Epply PSP 26224 downlooker. Made sure there were drip loops in the data cables for the downlooking radiometers.
PSP 16714 had been removed from this site yesterday due to a water leak.
26224 was a spare from the trailer, which needed an I2C address change. Previously it was address 85 (0x55), and I changed it to 91 (0x5b).
Sonic at this site has all wicks. Tom used datascope as a binocular.
At the site, noticed that main soil mote (ID12) was not reporting. Power cycled it.
Left at 14:40.
Dec 6, 10:20 am, Tom, Gordon
Fog, light rain, which stopped.
Installed TP01 at aux soil (mote ID20). This is the TP01 which was removed from site 1 this morning. Didn't check the serial number. There is no serial number on the connector. Tom thinks it might have been unit 013.
Left 10:42 am.
Dec 6, 09:20 am, Tom, Gordon
Light rain.
RH has been reading -3 % here since last night. Removed unit 015. Goretex sock was intact, a damp black film present on the goretex - probably from dust. This unit is covered with a brown resin where the transducer is soldered.
Brought 015 back to car to let it dry out a bit. Inside of din socket was damp. Sprayed it with some canned air. Put back in unit, but RH still bad. Replaced with 021.
Tom removed Qsoil, ECHO003, which had been reporting intermittently. Replaced with unit 020 which we had just removed from aux playa1. Values look good.
Left 09:53
Dec 6, 08:25 am, Tom, Gordon
Removed all aux soils, sensors, mote, and post.
Removed dead ts013 at main site and buried ts017 inserting it into the holes of ts013.
ts017 had been hanging in air since last night.
Left site at 08:40.
A little after 15:00 MST Dec 5, the TRH at wslope6 failed:
TRH23 -40.21 -3.99 0 0\r\n TRH23 -40.21 -3.99 0 0\r\n TRH23 -40.21 -3.99 0 0\r\n TRH23 -40.21 -3.99 0 0\r\n
Note that the raw values are 0.
I've tried:
eio 5 0 eio 5 1
but it didn't help.
Fog was prevalent all over the valley yesterday, including at 6. We visited the site at 16:15 but didn't notice that the TRH was out.

Dec 5, 1158 MST: Joe Young disconnected Tsoil at Playa main soil site and pressed the white reset button on the mote.
Gordon looked at the data and it is reporting Gsoil, Qsoil, and TP01.
Dec 4, 6:15 pm, Tom, Gordon
visited eslope5 to diagnose problem with Rsw.out data, which has been looking bad for a while.
The inner dome of downlooking Epply PSP 16714 was 1/3 filled with water. Removed.
12/4 16:15 pm, Tom, Gordon
The mote at this site (ID3) has been removed since 12/3 when we couldn't get it to report data.
Replaced this mote with ID19, swapping radios. All soil sensors were reporting, including Tsoil. Before we left noticed that the 4th Tsoil value went bad.
Dec 4, 09:15 am
At the playa site yesterday, we noticed that the soil mote at the rad stand was ID3 and the auxilary mote was ID8. The XML configuration had them reversed. Hence, the web plots, netcdf files and cockpit are all labelling the soil variables incorrectly. I will correct the XML and re-run the netcdf covars and remake the plots.
12/4, 16:15 pm, Tom, Gordon
Opened door of aux mote (ID8) and checked voltage at white power connector: 11.5 V.
Sequentially pulled and replaced one sensor at a time. Voltage recovered to 11.6 when Qsoil, Gsoil, TP01 removed, to 11.7 when Tsoil removed.
The mote was running all during this time. It is supposed to shut down when the voltage falls below 11.9. It appears that the mote voltage measurement was erroneously high, see plot and
discussion below.
When Tsoil was unplugged, Gsoil and TP01 were reporting, no Qsoil.
When Tsoil was plugged in, Gsoil abruptly changed from 9.4 to -1.
Replaced battery. Voltage 12.46 without Tsoil. Now receiving Q,G and TP01. When Tsoil was plugged in, it caused step change in G and Qsoil. Left Tsoil unplugged. Note that Qsoil started reporting after the battery was replaced.
Attached is a plot of soil variables from aux at playa1. When the Tsoil goes bad it effects the measurement of Vmote and Gsoil. When we arrived at the site and disconnected Tsoil then Vmote dropped from 17 V to a more correct value of 12. The Vmote values of 12.5 V after 17:00 MST are with the replaced battery.

Dec 3, Playa motes at main site (near radiometers) and aux site (north of main) and Highland not reporting any data
Playa, 14:16 MST
Mote at main soil site is ID3: battery voltage = 12.5 V; reporting time information, but no soil data.
Mote at aux soil site is ID8: battery voltage = 11.4 V; disconnected gps, recycled power and data good.
However ID8 soon quit because battery voltage below 11.9 V (per JM).
Replaced aux battery w/ battery from main; now aux battery voltage = 13.5 V (perhaps 12.5 V was a typo).
Brought Mote ID3 and aux battery back to base
Highland, 15:54 MST
Soil mote battery voltage = 12.7 V.
Looking at data from motes:
mote_dump
showed continual reboot-like messages from the soil mote (ID22): "watchdog timer" and "sampling_mode=0", etc. No soil data. Yellow light was on solid.
Disconnected soil sensors and added them back sequentially. Data good until we connected Tsoil.
Replaced Tsoil w/ #0018 from Boulder (GM coated with fingernail polish in base).
Brought bad Tsoil back to base.
When Gordon and Tom were at E Slope on Dec 1, the main soil mote was not reporting, but the aux mote was reporting.
Then around 15:52 (while we were there), the aux mote stopped and, around 16:02 the main mote started.
On Dec 2 around 05:37, the main mote restarted.
