Summary: Installed thermocouple rods, veg height, spectral, no camera images found

Arrived at 9:44am. It was windy with clear skies. There was some fencing still around the tower but no sheep in sight. We started servicing the tower but then Sonia and Jake from the PBS student journalism project showed up so we stopped and returned later (1pm) when they had left.
I downloaded data from the tower and cleaned the radiation sensors and solar panels. The camera had no data on it â€“not sure why-it seemed to be running fine. Joeâ€”maybe check on this?
I also did spectral and Kyle did clip plots and veg height.
Sara installed the new thermocouple rods near the radiation sensors. Joeâ€”please update program in soil CO2 box for new thermocouples. And bring zipties for organizing wires in the box and more black conduit for protecting exposed thermocouple wire. The thermos are wired 2 to 32 cm starting at 1Hâ€”they take up a total of 15 channels. The first rod is channels 1-5 and is buried north of the radiation sensors. The second rod is channels 6-10 and is buried south of the radiation sensors. The third rod is channels 10-15 and is buried in the middle.

Veg Height (cm): Tape measure from ground to top of plant
23, 20, 29, 17, 19, 22, 10, 16, 23, 23, 30, 10, 21, 8, 23, 20, 19, 14, 20, 35, avg = 20.1, stdev = 6.7
