Twitchell Rice
2013-09-11

We arrived about 11:40 PDT. It was partly cloudy, breezy, and cool (19 C). The soil continues to dry out and the rice is super droopy with seed, about 65 cm high. I attended to the tower while Sara did spectral measurements and Dennis and Eva did clip plots. There may be a lower rice yield this year, Eva harvested quite a bit in her boots.

CO2 = 390 ppm (395 after cleaning)
H2O = 690 mmol m-3 (675 after cleaning)

p = 101.9 kPa
sos = 346.6 m s-1

7700 readings:
CH4 = 1.87 ppm (same after cleaning)
