Onsite today with Josh, and Reva (here just for a quick visit). Jacquie left to head back to Vegas today, thanks Jacquie!
Weather good, partly cloudy. Calm in the morning, moderate south wind by the afternoon.
We went out to the array a couple times. On our first visit we gave Reva the tour, had an initial look at the bad 4m hot film, and brought the callab laptop out to connect to the t1 csat3a with the wrong sampling rate. In the Campbell device config utility, the options for sampling rate were 10Hz, 20Hz, and "motor rate". I tried motor rate, which results in data at 60Hz. The bandwidth filtering parameter on that sonic is currently set to 20Hz, since the only faster option is 25Hz, which Steve says would be weird with 60Hz data. This was at about 2pm.
We got back to the 4m hotfilm after the 3pm sounding. At new t0 we checked the resistance of the 4m probe (16 ohms, while the good probe at 2m was 7 ohms). Since we were measuring upstream of the bridge electronics, presumably this was a problem in the probe. We confirmed by switching the 4m and 2m probes to the opposite bridges, which resulted in good data from the 4m bridge and bad data from the 2m bridge. So I replaced the 4m probe (SF5) with a good spare (SF7), which is now giving good data. I realized after getting back to base that I'd set the switches in the bridge wrong, so went back out to fix it. Data after 5:00 local is with the correct switch settings for SF7. Thanks to Steve for the remote support!
Other than that, we did the 10 and 3 sonde launches, showed Reva around the site, and talked about ideas for a sonde system using hydrogen. We also stopped to check out the drone operations out near the array.
Sorry Jacquie, I haven't taken any pictures yet...
