I arrived about 9:30 with Sara and Cove. It was clear, sunny and hot with a dying light breeze from the west. The weeds in the field continue look at little greener again this week. There was some water in the ditches.

When we arrived the LGR read:
9:43PDT, 21.89C, 141.65Torr, 14.908usec, 10Hz, 1.835ppm

I did not calibrate the LGR, probably should do it next time and reset its clock. I cleaned the 40um filter, it was only slightly dusty.

I swapped the LI-7500, sn 0418 came off and sn 0035 went on.

The radiometers were clean.

The new theta probes with the soil CO2 system seem to read a little high, but I don’t see any obvious problems. Maybe salinity?

Cove and Sara did the standard fieldwork.

I removed the old webcam and enclosure. It had been disconnected previously.
