I arrived about 8:30am with Jaclyn and Dennis. It was clear and cold with a little frost on the grass and heavy dew. The ground is wet from heavy rain over the weekend. Almost no wind – only a faint puff from the north-northeast. Harvest is progressing with fields to the west having been harvested and the north end of our field.

We pulled all the field sensors: soil temp, SHF, Theta probe and well. I also rotated the radiation boom to the north over the edge of the field. I cleaned the radiometers. We brought in the water pressure sensor for calibration. Its wiring was:
G = Blu/Yel/Shd
C5 = Wht
12V = Red
G = Blk

No power at the site when we arrived. The GFI outlet on the generator had popped. I reset it and all was well. LGR was down for about three days but the rest continued on batteries.

LGR reporting:
7:58PST, 6.02C, 144.05Torr, 16.050usec, 10Hz, 2.021ppm

I collected data and swapped cards.
