Bouldin Corn

We arrived at 14:25. It was sunny, mostly clear, and windy. We don't see sprouts yet in the field. The field looks smoothed, but we're not sure if they're planted corn yet.

Sam cleaned the radiation and flux sensors and refilled the wash reservoir. He also added a longer hose for the 7700 wash reservoir and moved the wash reservoir box down closer to the ground.

I downloaded met data and USB GHG data, but I wasn't able to connect to the Licor interface to see current CO2/H2O numbers. We seem to have all of our .ghg data until May 24 10:30. The Power LED status light was blinking in and out.

Joe turned off the power supply (AC/DC converter) and thought that the power supply was overheating, so he attached the power supply to the underside of the bottom boardwalk. Joe disconnected the 7700 to reduce the power load on the power supply, but the Licor interface still wasn't getting enough power, so he disconnected the whole interface.

Dennis and Sam removed the Kipp and Zonen CNR1 4-way radiometer sn 990181 and added new scaffolding cross bars at the top of the tower.

We left at 15:15.
