Bouldin Alfalfa

Arman and I arrived at 15:30. It was a clear sunny and mild winter afternoon. The alfalfa is about shin high and sparse. Arman did veg height and spectra measurements. I worked on the tower.

I collected the flux, met, camera, FD, and IRT data. I swapped the 7500 for calibration: sn 0035 came off and sn 75H-2514 went on.
0035 read: 436.0ppm CO2, 590.4mmol/m3 H2O, 19.7C, 101.3kPa, 98.7SS
2514 read: 443.5ppm CO2, 571.9mmol/m3 H2O, 19.1C, 101.3kPA, 98.1SS
I updated the pressure coefficients and restarted the box.

We left at about 16:00

On the way out we took the low road past where they had been working on the levee. It was soft and muddy enough to make me worry about getting through in the truck. Better to take the road on top of the levee.
