Arrived about 9am with Jaclyn. The usual road was blocked under the big bridge by a crane truck involved with the retrofit. We went in the back way but the usual road was open on the way out. The weather was clear, sunny and warm with a strong wind from the west. Two weeks ago the field looked wet from the bridge with water in the north third of the field. This week there was no standing water, but the pepper weed looks happier and there seems to be a sparse scattering of new flowers.

Systems were running well. LGR:
9:20PST, 27.49C, 131.25Torr, 15.644usec, 10Hz, 1.816ppm, 3466.9hr

I removed the LI7700, swapped cards on the CR1000 and reloaded the original program. The LI7700 RSSI was about 34.

I also removed the scroll pump (GVSP30 sn DG002) for maintenance and replaced it with a diaphragm pump borrowed from Frank. During the pump swap I calibrated the LGR.

Precal: 9:45, 27.69C, 156.66Torr, 15.661usec, 1.978+-0.002ppm
Post cal: 1.976+-0.002ppm

Before leaving with the LGR running on the diaphragm pump and the bypass valve adjusted: 10:48PST, 28.60C, 146.76Torr, 15.678usec, 10Hz, 1.865ppm

Copied data logger data files.
