We arrived at approximately 13:15 PST. It was partly cloudy and warm (20 °C) with a light breeze. The field is fully drained with no standing water or muddy areas. Laurie and I attended to the tower, cleaned the instruments, and downloaded the data.

7500 readings:
CO2 = 392 ppm
H2O = 523 mmol m-3
agc = 23.1 (after cleaning it was 20.1)
p = 102.95 kPa

7700 readings:
CH4 = 1.87 ppm
RSSI = 44 (bumped to 71 after cleaning)
The reservoir was full.

MET looked good.
