We arrived at approximately 11:30 PDT. Sunny and breezy, ~20 °C. The field has dried considerably. The surface is still muddy, but unsaturated. A lot of dead leaves on the rice plants. I checked the tower and did clip plots while Sara did LAI and spectral. About 30 waspies were trying to hibernate in the box, but I shooed their lethargic bodies away.

Current 7500 readings:
CO2 = 385 ppm
H2O = 700 mmol m-3
agc = 43.8

7700 readings:
CH4 = 1.85 ppm
RSSI = 27 (bumped to 66 after cleaning)

MET values looked fine. 7700 reservoir is about 2/3 full.
