We arrived at the site around 09:00 PDT. It was sunny and warm with a light breeze. The field is mostly golden but dotted with green and white. I attended to the tower and downloaded data, Kathleen did LAI and Patty did a vegetation height transect, well depth and moisture point.

LGR readings: 1.85 ppm, 22.31 C, 140.1 Torr, 14.72 us, 10 Hz

7500 readings:
CO2: 16.22 mmol m-3
H2O: 775 mmol m-3
P = 102.5 kPa
T = 27.1 C (vs. 21.0 C from the HMP45 – might want to keep and eye on that).
Diag: 248
Sos = 345 m s-1

Soil CO2 seemed good.
Met ok.

Veg Height (cm): Tape measure from ground to top of plant - pepperweed mostly dried out.Grass dry.
