Summary: Regular data collection/cleaning

2017-04-27
West Pond

We arrived at 11:45. It was mostly clear, sunny, and breezy. The green tule are 2-3 m tall near the tower. We didn't see any green cattails. They have mowed the east-west grassy road on the way to the tower. The trail leading to the tower is still overgrown.

Sam cleaned the radiation and EC sensors and refilled the 7700 wash reservoir; it was mostly full.

I collected met, USB GHG, and camera data. There were only 6 days worth of camera data, from 4/11 to 4/17. There was low power on 4/18 (BattV = 10.4 at 4:00 and then no met data until 7:30 when BattV = 11.3). The camera would've turned off if power dropped too low, and would not turn on again when power increased again.

LI7500 readings:
CO2 404.7 umol/mol
H2O 490.5 mmol/m3
T 22.3 Celsius
P 101.3 kPa
SS 99.3 -> 100.7 after cleaning

LI7700 readings:
CH4: 1.93
RSSI: 46.7 -> 82.3 after cleaning

We left at 12:00.
