Summary: Cold and wet, reinstalled C4 dendrometer, standard fieldwork, updated soil co2 program

I arrived at about 10:30 with Siyan. It was cold with a cold breeze and scattered showers. The ground is soggy and the pond looks completely full. The grass looks happy but still short, some of the native wild flowers are coming up. The rivers on the way up were brown and running high. I could see Mt Diablo but not the Sierras.

I put the dendrometer band back on Tree C4. It was mistakenly removed last time with the removal of the sap flow station.

I brought radios and a LattePanda to install but discovered I could not mount the LattePanda with touch screen in the box well. I think Iâ€™ll put a box together in the lab and swap the entire box at a later date.

I collected the eddy data from both towers. Siyan did the regular fieldwork, collected the other data and serviced the z-cams.

I updated the soil co2 program to use both C3 and C4 to drive the soil state switches. This seemed to fix the problem with the open CO2 profile not getting turned on.

The old cal panel for the FLIR was knocked around a bit. The ground is getting soft so I pounded in the posts a bit to firm them up and realigned things.
