Summary: Standard site visit. All generally well.

Mayberry
2013-08-05

We arrived about 13:30 PDT. It was breezy, sunny, and cool. The site looks the same, very green with a bit of standing old plant material mixed throughout. Laurie went out and grabbed water samples while I checked the tower readings and cleaned the solar panels. I double checked that the 7700 was communicating at 20 Hz (in the 7700 program settings). It was.

7500 readings:
CO2: 388 ppm (same after cleaning)
H2O: 660 mmol m-3 (same after cleaning)
signal strength = 96.3% (96.6% after cleaning)
p = 101.5 kPa
t: 23.3 C
sos = 346.3 m s-1

Current 7700 readings:
CH4 = 1.9 ppm variable +- 0.2 ppm (1.9 and more stable after cleaning)
RSSI = 11.7 (88 after cleaning)
The reservoir was 2/3 full. Topped off to 100%. There was a small piece of cottony plant material fluttering in the path, contributing to the variability in CH4 signal.

MET looked good.
