Summary: Alfalfa mown but not bailed. Data download. Took GPS reading of site location.

Twitchell Alfalfa
2013-08-14

We arrived at 10:45 PDT. It was sunny, breezy and warm (25 C). The alfalfa has been mown but not bailed. There remained a swath of unmown alfalfa under the radiation boom, which we cut down by hand. I downloaded data, and finally made a new Alfalfa-specific Loggernet connection for the Met CR1000.

7500 readings:
CO2 = 400 ppm (same after cleaning)
H2O = 540 mmol m-3 (same after cleaning)
SS = 93.1% (93.5% after cleaning)
T = 27.8 C
p = 101.4 kPa
sos = 349.6 m s-1

MET looked good. Radiation looked good.

I took a GPS reading of the tower location: N 38 06.904', W 121 38.802', -9 m
