Bouldin Alfalfa
2025-05-29

Dennis, Eden, Kyle and I arrived at about 13:00 PDT. There are still bales on our field but the field to the east is clear of bales. They should be planting corn here soon. We drove to the tower, Kyle came in her own car. It was clear sunny and mild.

I collected the flux, met and camera data. Dennis cleaned the sensors and then helped to swap the 7500: sn 75H-2669 came off and sn 75H-2180 went on.
2669 read: 415.3ppm CO2, 749.2mmol/m3 H2O, 27.7C, 101.5kPa, 93.8
2180 read: I didn't copy the readings but was worried the pressure was offset a little - not sure now.
I updated the pressure coefficients and restarted the box, but the pressures seemed slightly off.

I collected the 720 data from the uSD card. Then I updated the 720 firmware with the new interface software called CarbonWare. There were some bugs in the interface but it seemed to work. I restarted the 720 and checked that the CR6 had data when I reconnected the 720 to the data logger.

We left at about 13:30 PDT.

Estimated Next Mowing: 2025-06-08
