Camilo and I arrived at 14:45 PST. It was a clear and cool day with a cold breeze. There are still some puddles on our field, with green grass coming in around the edge of the field and on some of the drier spots in the field. The water level was 1.19ft from the top of the well pipe, and the pipe height was 1.19â€™ from the ground, so the water level at the well was basically at the soil surface.

Camilo cleaned flux and rad sensors and swap the 7700 hat with one with more spikes. The wash reservoir was mostly full; we topped it off. I downloaded met, camera, USB GHG, and PurpleAir data. Some of the PRI/NDVI channels had occasional NANs, so I reset power for all 4 sensors. I also re-wired the precipitation bucket from P1 to P2 to match the current program (it probably had the wrong wiring since we put the tower back up on 2019-12-13).

We left at 15:15 PST.

Back in the lab, there were only a few days of photos on the camera card. Running the card through Recuva did not unearth any new photos. The card is old and should probably be replaced. However, Joe previously tested this card in the lab over a few days, and did not have problems then.
