Summary: Regular data collection/cleaning, swapped 7500 for calibration

East End

Dennis, Ari, and I arrived at 11:50 PDT. It was a pleasant day, mild and partly cloudy with a slight breeze. The staff gauge read 31cm.

Ari cleaned the flux and rad sensor. Dennis topped off the wash reservoir.

I downloaded met, cam, and USB GHG data. We swapped LI-7500s for calibration: sn 1594 came off and sn 75H-2667 went on. I uploaded a new config file, updated the pressure coefficients, changed the eddy clock ~+45sec to match the laptop time, and reset the box. I checked that the USB was logging and the 7700 was connected.

LI-7500 readings (sn 1594 --> sn 75H-2667):
CO2 390ppm --> 417
H2O 443ppm --> 380
T 20.7C --> 20.8
P 101.4kPa --> 101.4
SS 89--> 101 after cleaning
LI7700 readings:
CH4 2.0ppm
RSSI 58--> 83 after cleaning

We left at 12:10 PDT.
