Cool calm day, mostly clear sky with occasional scattered clouds.
Steve and Isabel got the Ubquiti link running to the sounding site. It had been very unreliable despite having good line of sight over a distance of only about 350 meters, but by rising the antenna to 3 meters at the sounding end and about 6 meters at the base trailer end it has become much more stable. So far nidas data from the surface met and CL61 ceilometer data at the sounding site is being transferred back to the ISS2 data manager, however the sounding system is not yet configured for data transfers.
After discussions with Sebastian, programmed up some new scans for the wind lidar and are testing them out. The scans include a 0-degree elevation scan over Deer Creek reservoir, a 2 deg scan all around (the land slopes gently upward towards the north so a full 0-deg scan to the north would be blocked), low level RHI scans towards the reservoir as well as up the valley (towards the Provo River supersite) and Daniels Canyon. Also are testing a high elevation scan (75 deg) for VAD winds instead of our usual 35 deg VAD scan.
Installed our third PA-II-SD aerosol sensor at the Provo River supersite, where it will use Sebastian's mobile wifi network to connect to Purple Air's cloud service. The data can be accessed at this link.
Launched the daily sounding on schedule at 4:15pm MST (2315 UTC). The leaky Helium cylinder from yesterday was still leaking slightly today so moved the regulator to a different cylinder and no leaks were detected, suggesting an issue with the previous cylinder fitting.
