Playa1 Snow Clearing

10:35am MST 31-12-2010

Playa1 site visited, snowing heavily on arrival. Radiometers were clear on arrival.

Solar panels cleared, no ice was found.

2.5 inches of drifting snow on the ground as of time of visit. TRH at site sounds very rough.

Power cycled Highland at 7:00 AM. 4 inches of snow. Cleared off solar panels and radiometers.

Replaced batteries at West Valley at 8:15. 10 inches of snow.  Cleared off solar panels and radiometers. ETI precip gauge is filled with snow and not melting into antifreeze. Needs to have known amount of antifreeze added. UU has antifreeze at Mtn Met Lab.

Multiple snow depth samples averaged to 8.9 cm at Hiland3 at 1700 UTC 1 Jan 2011.

Power recycled twice at Hiland3 at 1000 and 1005 MST (1700 and 1705 UTC) while on phone with Tom Horst. Recycles were unsuccessful at allowing Tom to ping the site, which had been power-recycled earlier this morning by John Hortel, also to no avail. The station is, nevertheless, running the fan and collecting data on-site. Tom suggests that there may be an intermittency in the control line at this site, which will be handled by the ISFS crew arriving in Salt Lake City tomorrow.

TWH: the power recycle was successful, since I was later able to ssh in and data is being transmitted.
