Twitchell Rice: 2017-02-14 11:45:00 (DOY 45)
Author: Daphne Szutu
Others: Sam Chamberlain

Summary: regular data collection/cleaning

We arrived around 11:45. It was sunny and mild. The cattails have green shoots coming up from the water's edge by the boardwalk.

The water was lower than 4 weeks ago, when Kyle added the extra boardwalk.

Sam cleaned the radiation, 7500, and 7700 sensors. He refilled the wash reservoir; it was 1/3 empty.

I downloaded the met data, USB GHG data, and camera data. SoilT304 = -INF.

The 7500 read:
CO2 425.78 ppm
H2O 553.6 mmol/m3
T 15.28 C
P 102.4 kPa
SS 84.5 --> 85.2 after cleaning

The 7700 read:
CH4 2.31 ppm
RSSI 30.4 --> 70.4 after cleaning

We left at 12:15.
