6:00 - 6:18pm MST
Visited WSLOPE 6 to reset radiation stand mote, after data dropped out several days ago.
Upon arrival the mote was opened, and status lights appeared normal (green/red flashing indicating data collection and flow). Rad mote power cycled via on/off switch, lights returned to normal status pattern. Rad data flow appears to have resumed as of power cycle of rad mote. Station radio was not restarted, internally or manually. Mote battery measured at 12.58 volts upon visit.
Station solar panels were covered with snow and ice, and were cleared. As well, upward facing rads had 1/3 inch of snow and ice built up on the domes. Loose snow removed, ice was not removed due to delicacy of instrument domes, and in order to avoid scratching.
Station reporting normally in online plots.
Highland at around 7:30 AM, East Slope a little after 8 AM.
Highland bare ground; East Slope 2 inches of crusty snow left.
Went out at 2 PM and cycled power at Highland site. While that solved the immediate comms problem, it is apparent that the battery voltage is dropping and likely not going to make it through the night. Will check in the morning and swap batteries if necessary. East Slope battery also dropping at a high rate tonight.

sonic height measurement from pivot point to top of boom - 8.79m
Cleaned krypton
twh (3/2/11): high-rate data indicate kh2o cleaned at 14:17(!)
high-rate T-tc suggest mast down 14:07 - 14:19
high-rate u,w do not clearly show mast down, but u close to zero 14:09 - 14:19
13:38 - 13:50

11:00 - 11:30
Station was down this morning. A power recycle started up the station.
Measurement of the sonic height from ground to pivot bolt is 85cm
10:30 - 10:50
Reprogrammed router at base and installed. Would not work until a full power recycle on DSM.
Able to get into DSM via wifi and cell.
Router and cell units are #3
8:45 - 9:15am
Visited this site due to no transmission. Found a fault light on charging system. Unplugged everything from charging unit...this includes batteries. It seemed to reset charger and dsm was back up. The Verizon router was not syncing. Could not talk to the dsm via wifi or cell modem. Removed router and bringing back to base trailer to re-install settings.
Hiland and Eslope off the air early this morning. Low battery voltage may be the reason.
Will take a set of fresh batteries to each site.
13:30 - 14:30, Dec 21
Replaced Tsoil probe.
Lowered mast to clean krypton, clean solar, and clean radiometer
trailer test: brought probe back to trailer and did a visual check.
There was no sign on moisture in the connector. Did a simple ice
bath test and the probe was reading high. Will take back to Boulder.
twh (3/1/11): high-rate data indicate kh2o cleaned at 14:03
high-rate u,w suggest mast down 13:59 - 14:05, but light winds make this ambiguous
(3/3/11): high-rate pressure data confirm 13:59 - 14:05
12:00-12:15
Replace router with a new unit with the correct configuration.
This was the original router at ABC which was removed earlier today
router
10:30 - 11:00
Since power was still low at 2 decided to change out the DSM. Before making the change we use
the meter to verify volatge readings. The result was we found a loose connector on the main
power cable going from the power switch to the power panel board. Everything looks ok now.
We also changed the the router since we could not communicate withe DSM via WIFI or cell.
According to Gordon we still need to make another change in the router firmware.
Snow removal at solar panels and radiometers.
