Mayberry
2013-08-14

We arrived about 11:45 PDT. It was breezy, sunny, and warm. The site looks the same, very green with a bit of standing old plant material mixed throughout. Sara went out and cleaned the instruments at the tule tower while I downloaded data and attended to the flux tower. We forgot the vials for water samples. Sara reported that the net radiometer over open water was rather soiled with bird doodie.

7500 readings:
CO2: 400 ppm (same after cleaning)
H2O: 700 mmol m-3 (same after cleaning)
signal strength = 96.2% (96.5% after cleaning)
p = 101.4 kPa
t: 26.9 C
sos = 348.3 m s-1

Current 7700 readings:
CH4 = 1.9 ppm (same after cleaning)
RSSI = 22 (90 after cleaning, a personal record)
The reservoir was full.

MET looked good.

I took a GPS reading of the tower location: N 38 02.988', W 121 45.901', -1 m
