We arrived at approximately 11:10 PST. It was sunny and nice out, about ~11 °C with a mild breeze. The field remains flooded and bare. Laurie and I attended to the tower, cleaned the instruments, and downloaded the data.

7500 readings:
CO2 = 434 ppm (430 after cleaning)
H2O = 376 mmol m-3 (419 after cleaning)
agc = 20.3 (new format, after cleaning it was 17.4)

7700 readings:
CH4 = 2.75 ppm
RSSI = 55 (bumped to 66 after cleaning)
Filled reservoir (was low). Now that I think about this, it was low last week when Joe and I went out, but the other towers were not. Next time I’ll check the settings and the system for leaks.

MET looked good.
