Summary: Regular data collection, large blowdown of wetland tule/cattail

We arrived around 12:20pm. There was large blowdown of wetland tule/cattail between the solar panels and tower. Also looks like patches of blown over reeds everywhere.

We downloaded met data (connecting to CR1000 directly through USB-serial cable) and USB GHG data. I connected to the blue ethernet cable and used TightVNC Viewer to remote-desktop into the tower computer and transfer the camera data to the field laptop. No camera data between 12/21 and 12/26.

We cleaned the radiation, CO2, and CH4 sensors. We refilled the wash reservoir; it was only 1/4 full.

The 7500 read:
CO2 431ppm (this is similar to TA but is about 20ppm higher than the other Delta sites)
H2O 308mmol/m
T 9.3C
P 101.7kPa
SS 100.2 --> 101.2 after cleaning

The 7700 read:
CH4 1.96ppm
RSSI 50.9 --> 78.0 after cleaning
