Mayberry

We arrived at 10:00. It was clear and cool, hazy at the horizon. There was a recent and rather large fire in the fields east of Hwy 160 and the first couple of fields along the dirt road. Spots were still smoking when we arrived. New fencing going up in those same fields. The wetland looks browner.

The boom was blown 45 degrees to the E below the water radiometers, and Joe got in the water to move it back to the original position.

Joe collected water samples at 10:15 while standing in the water.

I collected USB, cam, met, and miniDOT data. Sam cleaned the radiation and flux sensors. The wash reservoir was 2/3 full and Dennis topped it off. We removed HMP45 sn U2120013 to move to TA for the HMP field test.
