Author: Cove Sturtevant

Summary: All good. Standard fieldwork.

Twitchell Alfalfa
2013-08-05

We arrived at 11:50 PDT. It was sunny and warm (21 C) with a light breeze. The alfalfa marches on, very flowery and buzzing with bees. I checked the tower readings and did spectral measurements while Laurie did clip plots and LAI.

7500 readings:
CO2 = 388 ppm (same after cleaning)
H2O = 630 mmol m-3 (same after cleaning)
SS = 93.0% (93.4% after cleaning)
T = 23.8 C
p = 101.5 kPa
sos = 346.8 m s-1

MET looked good. Radiation looked good. Cleaned the radiation sensors.
