Carlos and I arrived at 11:15 PST. It was mild, sunny, and mostly still. The field is mostly dry now with just a few puddles remaining.

We drilled new holes into the power box enclosure’s backplate and mounted it to the new metal pole with u-bolts.

I downloaded met, cam, and USB GHG data. I downloaded the PA data and power cycled it. I downloaded the IRT data by swapping the microSD card and using CardConvert to convert the fast data to TOB1 and the slow data to TOA5.

I changed the phenocam clock +1min from 12:02 to 12:03 to match the laptop time. I also changed the eddy clock +1min from 12:01 to 12:02 and restarted logging after the change.

Carlos cleaned flux and rad sensors and topped off the wash reservoir. There was a dead fly on the lower 7700 mirror.

We installed the eosFD chamber sn FD20180067 under the tower. I confirmed that its clock matched the laptop time and that sampling frequency was set at 5min.
