Cleared off solar panels. Brushed off lightly pyranometer- pyrgeomter clear. 6 inches of snow on ground. Access to site now a long carry unless someone brings a shovel and clears snow berm far back in cemetery.
12/30/10 17:00: John Horel found the West Valley station running. He recycled power and I (TWH) was able to ping the station successfully.
John also cleaned snow off the solar panels. The radiometers were still snow-free.

Upon arrival at trailer this morning, pam and flux computers in the trailer were in the state that they were put into on 23 December when an error appears to have caused a failure in numerous parts of the data system.
pam, which is used for s-plus realtime analysis was operating, but flux had become unresponsive. The /usr/local mount on pam did not contain any updated netcdf files from the isfs sites, so realtime analysis was not working. It was advised to restart both pam and flux, starting with pam, and then flux.
This was done, and pam restarted fine, but when remounting, the files did not appear. Then flux was restarted (using the power button due to unresponsiveness) which came back and I was able to start up cockpit and observe that data was flowing properly.
However, when flux was restarted, pam crashed, and became unresponsive. It is apparent that pam mounts flux, and when flux dissapears, pam does not work. The result was a need to restart using the power button. This operation resulted in pam not remounting flux on startup, and therefore does not have access to netcdf data or s-plus.
For future situations where flux is down, it is advised to shut down pam using the computer controls, then reboot flux, and then restart pam, so that it proceeds in mounting, as well as allows flux to reboot.
pam will need to be addressed in the near future, as it is not particularly useful at this time.
Restarting flux has allowed Tom Horst to have access to base computers again, and netcdfs have resumed coming into the computer. Realtime analysis can be done on flux for now, and cockpit is working just fine. It is reported that Tom can no longer access flux. This will be addressed in the morning of the 28th.
An update to the status of spare batteries:
There are 6 batteries in the mountain met building. as of 27/12/2010 5:30pm
1 is charged to 12.77 volts, another is charging overnight. The others will be charged tomorrow and wednesday.
Impending precipitation events and cloudiness mean the ISFS stations will be likely under cloudy conditions from midday tomorrow for up to 84 hours, or more. Spare batteries are being charged to be available for replacement.
The charger that was bought by the Semmer/Stumpy crew indicated that the first battery charged was 'bad' and it is holding a charge of 12.77 volts, so hopefully the charger is incorrect.

Mote power cycling from yesterday did not result in rad mote at river7 functioning.
river7 site was visited to test the sensors/mote and replace the mote if necessary.
Sensors were tested and the mote was found to not be operating. The problem was tentatively identified as a cracked solder on the oscillator for the real-time clock/calendar chip. This results in the 1 second green 'heartbeat' led not lighting. The mote in question is mote 17.
Thus the spare mote: 08 (Channel: B) was connected to the battery/sensors, and turned on, and its LEDs indicated that it was working normally. Mote 8 has been installed, and is locally collecting the data on it's microSD card. It is possible that we can transfer the xbee radio from mote 17 to mote 8, allowing it to communicate with the tower and transmit it's data. But for now, the station radio would have to be reprogramed to receive data from mote 8. Thus it is working in local storage mode only. The transfer of radios may take place tomorrow, and requires disassembly of both motes 17 and 8.
John Militzer has also indicated that he can send a new mote and pre-programed radio from Boulder so that the radiation stand can be communicated with. This is another option.
It has been discussed that the priority is collecting the rad data, and it is not vital that this data be immediately available to project scientists. Though in the interest of ensuring data quality, it makes sense to have the data accessible.

Visited Riverton 7 radiation mote after it failed to return values several days ago. Data resumed flowing on 26 Dec between 9Z and 20Z, without any manual input.
Upon opening the mote, there were no status lights blinking. I power cycled the mote with the on/off switch, and the status lights indicated that it was restarting itself:
all 3 lights flashing rapidly, then off.
Following restarting the yellow GPS light remained on constantly. I tried recycling again, and clearing off all snow and ice from the GPS antenna, but the result was the same.
The reset button was pressed, and the same outcome.
Rad battery level was measured at 12.84V, so this does not appear to be a low battery issue.
The station has been left in this status, with radiation data not reporting. This will be addressed in greater detail during daylight on Monday the 27th.
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.
