Clear day with some light haze throughout the day. Spent the first part of the morning with Matt doing an outreach activity at the Upper Provo site. Set up possible additional outreach for next Friday with a group of middle school students. Bill also contacted about an outreach opportunity with some graduate students next Thursday. It was announced on Slack that there will be no IOPs in the next 48 hours.
ISS1 – all systems running nominally again today with profiler status: @1656 100m: 4.35A @50V & 1.833A @ 32V, and @1700 150m rass: 3.65A @ 50V & 1.883 A @ 32 V
ISS2 – The lidar is running but still using lower resolution scans. Laptop software reports that the hard drive is still ~85% full. However, the lens appears to be frost free as of this afternoon.
ISFS – No issues today, all systems running. Matt took some Leica measurements this afternoon.
Soundings – The students reported that the gas regulator or meter was frozen during the overnight soundings when they switched tanks, so it appears that they estimated the volume of gas, as the spreadsheet has ’20ish’ entered for helium volume for a couple of soundings. The issue was not recorded for their last sounding. We found the gas meter had been set atop the oil heater in the trailer in order to warm it up, which worked well. System was functioning normally for the daily sounding. There was no surface wind during the sounding, so Matt and I, out of curiosity, unspooled the string before release. The balloon went nearly straight up and we were able to follow it visually until it reached 500 mPa in altitude.
