Summary: Field senescing. Regular field work. Data download.

Sherman
2013-07-26

We arrived about 14:10 PDT. It was sunny, windy, and warm (27 C). There was a lot of water under the bridge on the way in but the field was dry. The plants are mostly tan with a bit of dull green and dry flowers. I measured the general vegetation height at about 50 cm.

I checked the tower and downloaded data while Yanel did spectral and Laurie did soil CO2 flux and moisture point. I did well depth at the end.

No ant traffic in the computer box.

LGR readings: 1.85 ppm, 14:21, 27.8 C, 130 Torr (adjusted to 146 Torr), 12.6 us, 10 Hz

7500 readings:
CO2: 15.6 mmol m-3 (15.8 after cleaning)
H2O: 790 mmol m-3 (750 after cleaning)
diag: 248
p: 101.5 kPa
t: 29.6 C

MET looked good.
Soil CO2 looked good except for Ref_ST_1 which was reading 53.3 C. This may have been due to the sensor being on, because by the time we left it was reading 46. I will check the data.

Cleaned radiation instruments.

I checked the sns and MUX locations for the soil CO2 probes in the east profile at the surface (sn G0150036, MUX channel 4) and deep (sn G0150037, MUX channel 6) locations.
