Twitchell
7/1/2010

Arrived about 10am with Jaclyn. It was clear, sunny, warm, but enough breeze to keep my long sleeves on. The rice looks okay, still some weeds and a little thin near the tower radiometers. It looks like it was planted less densely this year. I think the rice grew a lot in the last week.

I cut grass around the tower and box. In the processes I cut the cable for the Theta probe to the south. I removed this probe to repair in the lab. I also pounded fence posts to mark the tower, box and rain bucket and a junction in the AC line back to the generator. I’m hoping the field crew can mow up to these markers.

Systems were okay. The serial port to the CR1000 had hung up for about a week, but the data is safe on the CF card.

LGR readings:
9:56, 27.68C, 150.75Torr, 13.927usec, 10Hz, 1.850ppm, 13726ppm, 386.51ppm

Met Frank to transfer so data.

Left for Sherman about 12:30
