Twitchell Rice
2014-12-10

We arrived around 12:30 PST. Breezy and overcast. Water level was high. The LVD was on but the batter was at 12.5 so I reset the solar controller to turn the tower back on. Downloaded data.

Pulled SHF plate #1 for testing/fix.

Rain gauge bucket was full. I declogged it and let the water run through it.

Adjusted rain gauge – turned both screws one half turn clockwise.

Readings:
CO2 = 294 ppm (421 after cleaning)
H2O = 116 mmol m-3 (580 after cleaning)
signal strength = 61% (88.8 after cleaning)
p = 101.8 kPa
t = 12.3 C
sos: 341.3 m s-1
CH4 = 0-2 ppm variable (2.3 ppm after cleaning)
RSSI = 1.3% (61% after cleaning)
Refilled reservoir.

Met looked good.
