DWR Corn
2012-11-29

We arrived around 08:15. It was breezy from the south, cold, and cloudy. The fields near the road have had most of the biomass removed, but the fields near the tower still have a lot of corn litter.

We reinstalled the ground sensors, replacing the wooden thermocouple dowels with plastic ones, and put the radiation sensors back out over the field. The Theta probes went in a -10, -20 and -30cm. We pulled the water pressure sensor (s/n 20010770) and took it to Twitchell. We cleaned the flux instruments and radiation instruments, and downloaded the data.

Tower readings:
CO2: 17.33 mmol m-3
H2O: 632 mmol m-3
diag: 248
p = 101.8

MET looked good after install. Clocks were good.
