Twitchell Rice

We arrived at 11:50. It was sunny and clear with a gentle breeze. The rice field had very little water in it.

I collected the met, USB GHG, and camera data. The camera data took about 20 minutes to move from the card to the laptop. We should try a new card next time.

Sam cleaned the radiation and EC sensors. He refilled the wash reservoir; it was __ full.

LI7500 readings:
CO2 418.6 umol/mol
H2O 414.2 mmol/m3
T 13.7 Celsius
P 103.4 kPa
SS 84.4 -> 85.1 after cleaning

LI7700 readings:
CH4: 2.02
RSSI: 36.6 -> 68.5 after cleaning

We left at 12:20.
