Twitchell Alfalfa
2014-07-31

We arrived about 15:00 PDT. It was hot and sunny with a nice breeze. The alfalfa has been cut and baled. Need to bring big clippers next time to cut the alfalfa under the rad boom.

Dennis did spectral.

Pulled the camera. Power to camera was fine. It would not turn on even with new batteries installed.

7500 readings:
CO2 = 378 ppm (398 after cleaning)
H2O = 680 mmol m-3 (630 after cleaning)
signal strength = 85.09% (94.77% after cleaning)
p = 100.98 kPa
t = 35 C
sos = 353.6 m s-1

Met ok.
Rad ok.

Veg Height (cm): Visual estimate - Just cut
