Summary: Year end data collection, swapped 7500 for calibration, removed IRTs - end of experiment, Rain bucket was plugged and full of water, roads are muddy

Bouldin Corn
2024-01-04

Dennis and I arrived at 10:35 PDT. It was clear sunny and mild with little to no wind. The field is flooded with water at the surface under the tower. The water level in the well was 48cm below the top of the pipe and pretty much right at ground level there.

Dennis cleaned the eddy and radiation sensors. We swapped the 7500 for calibration: sn 0042 came off and sn 0065 went on.
0042 read: 432.1ppm CO2, 410.7mmol/m3 H2O, 14.2C, 102.7kPa, 100.6SS
0065 read: 429.6ppm CO2, 394.9mmol/m3 H2O, 14.7C, 102.6kPa, 97.2SS
I updated the pressure coefficients and reset the box. Here the 7500 mount is frozen to the threaded post.
The 7700 read: 2.04ppm CH4, 52.0RSSI – 75 after cleaning
We refilled the wash reservoir by about 1/4.

The rain bucket was full of water. Dennis dumped the water and unplugged the hole with a bird spike.

I collected the flux, camera, met and PA data.

We removed the Corteva IRT sensors and box as that experiment is finished. I still need to get the data off the uSD card. CR1000X sn 1132, power controller sn 2963, and IRTs sn 1073 and sn 1076 were removed.

We left at 11:05

The on ramp to the highway is a muddy mess. I’m not sure the internal roads are much better.
