Summary: Scoped spot for wetland tower. 7700 RSSI=0 again due to dust.

Wetland Construction
2013-10-16

We arrived around 14:15 PDT. It was sunny, calm, and warm (25 C). We scouted out a new place for the wetland tower by driving along the berms. It appears that the layout of the wetland is nearly exact to the plan, and we found some decent spots with good westward coverage. Consensus was to run some footprint numbers before finalizing the location.

7500 readings:
CO2 = 15.3 mmol m-3 (16.3 after cleaning)
H2O = 450 mmol m-3 (340 after cleaning)
Diag: 249 (248 after cleaning)
t = 30.1 C
p = 101.8 kPa
sos = 346.0 m s-1

7700 readings:
CH4: 14 ppm (2.02 ppm after cleaning)
RSSI: 0% (77% after cleaning)
Reservoir was empty refilled.
