Summary: Water level in field low. All well.

Twitchell Rice
2014-02-05

We arrived about 12:15 PST. High clouds were increasing in coverage and it was cool with a very light breeze. The water level in the field was low but not below the surface. I downloaded data while Sara cleaned the flux and radiation instruments.

7500 readings:
CO2 = 394 ppm (405 after cleaning)
H2O = 398 mmol m-3 (362 after cleaning)
signal strength = 85.3% (90.0% after cleaning)
t = 13.6 C
p = 102.6 kPa
sos = 339.9 m s-1

7700 readings:
CH4 = 1.95 ppm (same after cleaning)
RSSI = 48% variable (61% after cleaning)
Topped off the reservoir.

Met looked good.
