Josh and I onsite.
Cool and windy today, mostly cloudy in the morning but clearing up a bit at the site in the afternoon. Thunderstorms and pea sized hail in town this evening, but I don't think the rain made it to the site.
Went out to the array after the morning sounding. We replaced the batteries at tt with fresh ones, since the voltage was getting pretty low after a couple cloudy days. We brought the EC150 head out to replace at 28m, but with wind gusts and storms in the area we put that off for another day. I connected the callab laptop to the CSAT3B at t48 to check on shadow correction settings. Looks like there is an option to enable or disable shadow correction from the instrument, which on this one is currently set to disabled. We swept off all the solar panels (a little dust accumulated, but not too bad), and I took one more (unsuccessful) stab at getting the PurpleAir to work.
Storm building over town, just as we left site this afternoon.
