Arrived about 8am with Jaclyn. Clear, sunny, nice wind from west, warming. The pepper weed is still in heavy bloom but the pollen seems less strong than two weeks ago. Cows far to the west.

All systems running. I swapped cards on the CR1000 and changed the program back to before the LI7700 was installed.

LGR: 7:48, 26.61C, 136.75Torr, 16.088usec, 10Hz, 1.893ppm, 2457.7hrs

In removing the LI7700 I noticed that the cap on the bottom of the water trap closest to the LGR inlet was missing. When I tried to put another cap on, the tubing broke being very brittle. I removed the water trap tubing and put a cap directly on the T-fitting. A good amount of the flow was going through the water trap. After capping, the LGR pressure fell about 10 Torr. The 40um filter was fouled. I didn’t have a new filter, but I had a used one in a littler better shape that I swapped in. Pressure improved.

Copied data.

Cleaned radiometers and rain bucket.

Pulled three moisture point probes in the field.

Left for Twitchell about 9:30

Returned about 2pm

Swapped card at the Levee tower.
