Bouldin Corn

Dennis, Carlos, and I arrived at 14:15 PDT. It was overcast, hazy, and mostly calm. The corn has been harvested right up to the tower but our field has not been disked yet. We didn’t see any tractor work near our field, but we drove by some tractor work in the fields between our corn and alfalfa sites.

Carlos and I downloaded all of the data while Dennis cleaned all the sensors. Carlos changed the eddy clock +~30sec around 13:31 PST and restarted logging. There were many sleepy wasps in the IRT box. Dennis evicted them by banging the box vigorously with a dried corn stalk and I sealed the cable hole with putty.

I removed the Purple Air sensor sn 84f3ebd5ffb1 because it has been having spikes recently. I brought it back for further inspection.

I checked the precip bucket and it looked clean.

The 7500 read: 403ppm CO2, 666mmol/m3 H2O, 28.2C, 101.6kPa, 95SS -- 101 after cleaning
The 7700 read: ??ppm CH4 (did not write), 35RSSI – 79 after cleaning

We left at 14:55 PDT.

Corn has been harvested. Arable is still on the edge on the field for now. We plan to move it back into the field after they finish disking or other tractor work.
