Summary: Levee tower stolen, fixed web cam file naming, fix SHF plate #3

Sherman
7/1/2010

Arrived about 8:30am with Jaclyn. It was warm, sunny and clear with enough of a breeze to keep it from being hot. The pepper weed flowers are a patch works of yellow and white, though more yellow than white. I didn't notice the cows, must have been far to the west.

All systems running and in good shape
LGR readings:
7:36, 27.31C, 135.97Torr, 15.840usec, 10Hz, 1.860ppm, 2817.4hr

I copied data and swapped the card. I cleaned the radiometers and check the tipping bucket.

I fixed a bug in the web cam batch file that caused single digit hours not to be prefixed with a zero in the file names.

I also fixed a loose wire on SHF plate #3 - should be okay now

To do:
Fix soil temp #2 @ 8cm
Add box/pump temp and cut off relay - see AM25T #25 and CR10X #4
Seal with silicon box wire plug
Reattached AM16/32
Reattach CR23X and seal soil co2 box

Left for Twitchell about 9:30

Returned from Twitchell about 1pm.

Checked on Levee tower and found that solar panels, batteries and data logger box had been stolen (see report). I decided to take down and remove the rest of the tower. Sonic head sn 000019, LI7500 head and box sn 0418, tubing cables, two tower sections, guy wires and blue battery box were removed. Left in the ground were two guy anchors and two rebar for the tower base. These I will remove next time out.
