We arrived at approximately 11:25 PDT. It was partly cloudy, warm, with a very mild breeze. No change since last week. We downloaded data and cleaned the flux instruments. We may want to ask when they plan to plant or disc the area around the tower. The radiation instruments are still off the field.

7500 readings:
CO2 = 402 ppm
H2O = 600 mmol m-3
agc = 21 (after cleaning it was 19.7)
p = 101.92 kPa

7700 readings:
CH4 = 1.95 ppm
RSSI = 27 (bumped to 68 after cleaning)
The reservoir was full.

MET looked good.
