Summary: No change in plowed fields, camera clock off by 8 months, quick data collection

Bouldin Alfalfa
2022-12-13

I arrived at about 16:30. The sun was going down as I arrived. No change in the fields being plowed. The levee road has a bunch of fresh soft gravel on it – passable but not in great shape. The alfalfa was clumpy with veg height from 0 to 20cm but the clumps looks green and healthy.

I collected USB, met, camera, FD and IRT data. I did not clear the FD chamber’s memory.
The 7500 read: 429.3ppm CO2, 353.0mmol/m3 H2O, 9.6C, 101.9kPa, 105.0SS
The Stardot camera had adjusted is clock by 8 months. I changed 2022-04-13 16:44:00 to 2022-12-13 16:45:33

I cleaned the outside and inside of the camera window. There might be a small change in the FOV since I had to slide the camera back and forth.

I have just noticed that the reflected PAR sensor is not in a great location. It’s right next to the big square tube of the radiation boom. I don’t think there is enough cable length to move it much, but a new mount on the bottom of the boom would work.

I left at 16:53
