Mayberry
2013-07-26

We arrived about 15:05 PDT. It was warm, windy, and sunny. The site looks the same, very green with a bit of standing old plant material mixed throughout.

I attended to the tower and downloaded data while Laurie and Yanel went out and took water samples.
I checked the sonic sn (074417). I had planned to bump the flux system to 20 Hz but hadnt remembered that I needed to bring a connector for the sonic at this site. Will bump to 20 Hz next week.

7500 readings:
CO2: 393 ppm (same after cleaning)
H2O: 760 mmol m-3 (same after cleaning)
signal strength = 95.7% (96.2% after cleaning)
p = 101.5 kPa
t: 28.7 C
sos = 349.0 m s-1

Current 7700 readings:
CH4 = 1.75 ppm (1.9 after cleaning)
RSSI = 7.7 (88 after cleaning)
The reservoir was empty. There was a crusty on the edge of the bottom mirror that was not being removed with spraying. I refilled the reservoir and cleaned the crusty.

MET looked good.
