We arrived at approximately 11:45 PST. Breezy with a visible set of rain clouds coming in. The field is very senescent, with hard yet moist soil. I checked the tower, cleaned the flux instruments, and downloaded the data and camera pics. Sara did LAI and spectral.

Current 7500 readings:
CO2 = 375 ppm
H2O = 425 mmol m-3
agc = 43.8

7700 readings:
CH4 = 1.9 ppm
RSSI = 25 (bumped to 69 after cleaning)
Topped off the reservoir.

MET values looked fine considering they are gathered around the tower.
