Twitchell Alfalfa: 2013-07-31 13:50:00 (DOY 212)

Summary: Alfalfa was rather fragrant today. All well.

Twitchell Alfalfa
2013-07-31

We arrived at 13:50 PDT. It was sunny, warm (25 C), and breezy. The alfalfa continues to grow strong. It was flowery and fragrant. General vegetation height was 60-70 cm.

The radiation 10x was still working when I arrived. I think the problem was the LED sensor that I removed last week.

7500 readings:
CO2 = 367 ppm (same after cleaning)
H2O = 580 mmol m-3 (same after cleaning)
SS = 93.1% (93.5% after cleaning)
T = 27.0 C
p = 101.5 kPa
sos = 349.8 m s-1

MET looked good. Cleaned the radiation sensors.
