Arrived about 10am with Jaclyn and Marga. Cool, mostly sunny, high thin clouds. Nice wind from the west. The rice field is knee high in weeds and they will get sprayed with herbicide today and fertilizer to follow. Maybe start flooding the field next week. Talked with Dennis Pallucca. They need an expert on great garter snake.

Systems were running. Sheep on east side of road.

LGR pressure was 130Torr adjusted bypass valve. Clock on PDT adjusted from 10:27 to 9:18.
Init: 10:23, 28.84C, 145.09Torr, 13.899usec, 10Hz, 1.8055ppm, 16661.55ppm, 390.20ppm

Calibrated with 3.276ppm CH4 and 433.0ppm CO2 tank 1750psi. Last cal May 20, 2010
Precal: 10:26, 129.6Torr dropping to 119Torr, 3.30+-0.05ppm CH4, 430+-1ppm CO2
Postcal: 3.26+-0.001ppm CH4, 429+-1ppm CO2

System back at 10Hz.

Swapped CR1000 card, copied data, downloaded plantcam images.

I took photos of sonic heading for Google Earth check.

Left about 11am for Sherman
