A variable weather day. It was snowing again overnight and early this morning (leaving a couple more inches of snow), then that cleared out to a nice sunny morning. By the middle of the day it clouded over and a cold wind picked up, and by evening it was snowing again. Some of today's activities:
Cleaned about 2 inches of snow off the Modular Profiler antenna around 1815 UTC.
Cleaned about the same amount from the RASS dishes around 1940 UTC, and cleaned off some remaining snow melt and ice from the antennas.
Around 1930 UTC the draw on the amp power supplies was 4.37A on the 50V and 1.836A on the 32V supplies in winds mode, and 3.66A on the 50V and 1.885A on the 32V supplies. Interestingly later in the day when the outside temperature had dropped to around 18F, the 50V draw had jumped to 5.2 - 5.6A in winds mode. John says this is expected when it's very cold.
The wind lidar stopped transferring data last night. I initially thought it was just a communications issue, but it turned out to have stopped part way through a scan cycle for some unknown reason. Windforge wasn't responding but the computer responded to Monit requests and pings. In the end climbed up to the roof and did a hard restart. Data happened to restart flowing at 2220 UTC (on 2/22/22, is that a coincidence or something else ... 8-)
The 4:15pm sounding was delayed because of a lack of Helium. The students drained out the last two tanks in a couple of soundings last night, fortunately Sebastian brought out a couple more cylinders. Steve assisted with this cold and rather windy sounding.
Attended the daily planning meeting (and a couple of other meetings) where the PIs discussed a possible final IOP tomorrow night.
