We arrived at approximately 12:10 PDT. It was warm and breezy. No change since last week. The area where the ground sensors were still has not been disked, so I left the radiation boom in. Just a passing site visit today. We checked the data readings, cleaned the flux instruments, and changed the desiccant in the pyranometer. There remains an insect farm in the wooden box and ant activity in the solar controller. I put ant bait near the solar controller.

7500 readings:
CO2 = 339 ppm (398 ppm after cleaning)
H2O = 833 mmol m-3 (445 after cleaning)
agc = 42.4 (after cleaning it was 17.6)

7700 readings:
CH4 = 1.93 ppm
RSSI = 45.7 (bumped to 70 after cleaning)
The reservoir was full.

MET looked good.
