Twitchell Alfalfa
2014-06-26

We arrived about 15:00 PDT. It was hot and sunny with a nice breeze. Sara and Kathleen did a veg height transect while I attended to the tower and downloaded data. We need to bring the large shears next time to cut down the tall grass around the tower.

7500 readings:
CO2 = 385 ppm (395 after cleaning)
H2O = 700 mmol m-3 (600 after cleaning)
signal strength = 93.4% (94.4% after cleaning)
p = 101.3 kPa
t = 26.6 C
sos = 348.9 m s-1

Met ok.
Rad ok.
