Twitchell Alfalfa
2014-08-07

We arrived about 13:45 PDT. It was hot and sunny with a nice breeze. The alfalfa is regrowing steadily. I attended to the tower and downloaded data while Sara clipped the veg underneath the radiation boom and did veg height. Still need replacement for autocam.

7500 readings:
CO2 = 390 ppm (395 after cleaning)
H2O = 775 mmol m-3 (715 after cleaning)
signal strength = 92.35% (94.79% after cleaning)
p = 101.1 kPa
t = 32 C
sos = 352.6 m s-1

Met ok.
Rad ok.

Veg Height (cm): Tape measure from ground to top of plant
20, 8, 12, 15, 10, 10, 11, 16, 15, 15, 22, 21, 25, 10, 15, 23, 17, 12, 20, 8, avg = 15.3, stdev = 5.18
