Summary: Standard fieldwork and data download. Patty's first time out to the field sites. Rechecked sonic direction.

Sherman
2013-10-02

We arrived about 09:15 PDT. It was partly cloudy and cool (17 C), with a moderate breeze. The site looked generally senescent and trampled.

I attended to the tower and downloaded data while Sara did moisture point and soil CO2 flux, Patty did spectral, and Patty and I both did well depth measurements.

LGR readings: 2.0 ppm, 09:19, 25.4 C, 135.0 Torr (adjusted to 145.5 Torr), 12.53 us, 10 Hz

7500 readings:
CO2: 17.7 mmol m-3 (18.1 after cleaning)
H2O: 530 mmol m-3 (520 after cleaning)
diag: 248 (247 after cleaning)
p: 101.7 kPa
t: 19.4 C
sos: 343.2 m s-1

MET looked good.
Soil CO2 looked good, except that Ref_ST_1 and Ref_ST_4 are now both out (I think Ref_ST_4 was out previously)
Cleaned radiation instruments.

Ive been playing with the footprint from Mayberry and Sherman, and wanted to precisely double-check the sonic direction. The North notch on the sonic was measured at 2 degrees North (magnetic).
