Summary: Pepperweed continues to dry out. Standard field work and downloaded data. HMP45 fan dead.

Sherman
2014-06-12

We arrived around 9:50 PDT. It was sunny, quite windy, and warm. The pepperweed continues to dry out, and the field now looks quite brown. I attended to the tower and downloaded data while Madeline did soil respiration and vegetation height measurements, Kathleen did LAI and moisture point, Joe did well depth and checked out the box and power for the Picarro / Forerunner chamber test.

Joe noticed the HMP45 fan was dead but didn't have a fan to replace it. Need a fan to swap in next time.

Madeline noticed a Vaisala probe lying on the ground near profile B (sn G0150035) – looks like it was the one that was replaced last week.

LGR readings: 1.86 ppm, 09:59, 22.26 C, 137.94 Torr (adjusted to 143.7 Torr), 14.73 us, 10 Hz

7500 readings:
CO2: 16.47 mmol m-3 (same after cleaning)
H2O: 552 mmol m-3 (same after cleaning)
P = 100.14 kPa
T = 22.61 C
Diag: 249 (same after cleaning)

Soil CO2 ok.
Met ok.
Cleaned radiation sensors.

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