Summary: Regular data collection, swapped sonic, water puddles in LI7500 box

We arrived at 12:25. It was cool, foggy, overcast.

There was a lot of water in the LI7550 box, but the box was closed securely. A lot of water fell out when Kyle opened the box, and there was a lot pooled at the bottom of the box. Not sure where the water could have come in. The numbers seem fine and everything still seems to be working. Elke mopped up the water with rags.

We switched out the Gill sonic anemometer: sn 153804 came down and sn 124215 went up. The new anemometer has upgraded firmware to correct for the W bug. We made sure the N-orientation of the anemometer was the same between the old and new sensor.

I downloaded met data and camera data through TightVNC Viewer and downloaded GHG USB data. From the datalogger, SHFP(2) = NAN.

The 7500 read:
CO2 444.0 ppm
H2O 355.0 mmol/m3
T 7.6 C
P 102.1 kPa
SS 97.0 --> 100.7 after cleaning

The 7700 read:
CH4 2.16 ppm
RSSI 39.8 --> 85.5 after cleaning

We left around 12:50.
