Bouldin Alfalfa

We arrived at 10:05. It was sunny with blue skies, but there was smog covering most of Mt. Diablo. It was mild with no wind.

Joe cleaned the EC/radiation sensors and the precip bucket. The bucket was dirty but there was some water in the tipper. He also refilled the wash box; it was 1/2 full. Sam took clip plots samples and veg height measurements. I collected met, camera, and USB GHG data. I also confirmed the heating/wash cycle for the 7700.

LI-7500 readings:
CO2 510.5
H2O 630.0
T 20.1

LI7700 readings:
CH4 2.97 --> 2.8 after cleaning

We left at 10:25.
