Summary: Inlet not running. Adjusted 7550 clock back to standard time and removed Date/Time fields from GHG output.

West Pond
2013-03-14

We arrived around 13:00 PDT. It was warm and partly cloudy with a mild breeze. The inlet showed no flow but the water level at the tower was normal. I called Jim, he said we would prime the pump that afternoon. We all attended to the tower and downloaded the data.

7500 readings:
CO2 = 398 ppm
H2O = 625 mmol m-3
agc = 2.9 (0.4 after cleaning)
p = 102.1 kPa

7700 readings:
CH4 = 1.99 ppm
RSSI =62, bumped to 75 after cleaning
Reservoir was full.

MET looked good.

Dennis cleaned the radiation sensors and tweaked the net radiometer to make it level.

There are ants in the datalogger box (not too many, but they were on the wires). We should bring some ant bait just in case.

I adjusted the clock on the 7550 back one hour to keep the clock in standard time (daylight savings “spring forward” was last weekend). Time change from 12:24 pm to 11:24 am. I also removed the Date and Time outputs to the data stream since this information is already included in the Seconds and Nanoseconds fields.
