Another cold day with periods of snow. Lou and Liz arrived last night and today we began preparations for teardown. We dug out snow from around the profiler and other areas of the ISS1 site. The profiler was down from around 18 - 19 UTC while we worked in the profiler enclosure and removed the covers from the two south RASS dishes. We also organized boxes and packing material, and backed up data.
Adjusted the wind lidar scanning cycle for the final IOP tonight. I added a 50 m resolution sector scan over the DC supersite and sounding area since there has been patchy fog rising from the nearby ponds. Most of the other scans are 100 meter scans trying to observe the air flow over the wider valley. The scan cycle repeats approximately every 15 minutes and includes 100m PPI scans over the wider valley, RHI scans towards the Provo RIver supersite to the north, Daniels Canyon to the east and the Deer Creek reservior to the south, as well as a 2-minute vertical stare (which allows the WALS software to estimate boundary layer depth) and a 75 deg PPI for VAD winds.
Launched two soundings this afternoon, at 2:50pm (delayed from 2:30pm by the snowy conditions and a frozen padlock on the Helium trailer) and at 4:30pm (delayed by a ground check failure requiring a reset of the whole system). Eric, Sebastian and Alexei will be launching the final soundings over the campaign overnight.
