We arrived about 9:30 PDT. It was sunny and warm with a light breeze. The pepperweed is super tall and dense with a white powdery fungus that billows up and makes you think of anthrax. Joe attended to the tower and downloaded data. Sara did soil respiration but the IRGA was giving the high humidity warning again, so measurements may be bad. She also did moisture point and LAI measurements. I did spectral, veg height, and well depth.

Joe tried to set up the autocam to record raw images at midday.

LGR readings: 1.955 ppm, 09:29, 21.35 C, 130.2 Torr (adjusted to 143.3 Torr), 14.776 us, 10 Hz

7500 readings:
CO2: 17.08 mmol m-3 (same after cleaning)
H2O: 590 mmol m-3 (same after cleaning)
P = 102.1 kPa
T = 19.3 C
Diag: 249 (same after cleaning)

Met & Soil CO2 looked good.
