Arrived about 7:30PDT. Got key for new lock on gate. Cool, sunny light breeze.

Swapped LGR. LGR #2 in place was in slow flow mode 128 Torr and 10usec. Replaced with LGR #1 about 7:13 PST in slow flow.

19.58C, 156.38 Torr, 18.178 usec, 1.929 ppm

Ran cal gas (1.976ppm). Last cal was in lab on 8-12-2009 with 1.898 ppm tank

Pre cal 1.933ppm
Post cal 1.976

Switched to HI flow, pressure crept down slowly to 144.9

8:17 PDT
25.59C, 144.9 Torr, 18.000 usec, 2.009 ppm, 10Hz, 3123.8 hr

I cleaned and repair corroded terminals on the battery that powers the soil moisture data logger.

Made soil moisture measurements:
