Mayberry
2014-04-10

We arrived around 10:45 PDT. It was sunny and warm. The vegetation is really taking off, lots more green. Also a lot of algae blooms in the open water.

Sara and I attended to the tower and downloaded data while Joe did some cleanup on the berm. I drilled a larger hole for the pin in flux instrument pole. It should be easier to raise and lower the instruments now.

The thermocouple shield in the 7700 path broke. Need replacement.

I took a GPS reading of the new tower location, averaging measurements over 2 minutes:
38.049867Â° N
121.765017Â° W

7500 readings:
CO2: 428 ppm (same after cleaning)
H2O: 591 mmol m-3 (same after cleaning)
signal strength = 88.2% (89.2% after cleaning)
t: 18.6 Â°C
p = 101.6 kPa
sos = 343.2 m s-1

Current 7700 readings:
CH4 = 1.98 ppm
RSSI = 40 % (89% after cleaning)
Reservoir was full.

Met looked great.
Cleaned radiation sensors.
