Sherman Wetland

Joe, Camilo, and I arrived at 15:20 PST. It was a cold day, but mostly sunny with foggy horizons. The wetland was mostly brown but there were some green reeds on patch edges, and some green tule clumps. The water level was 81cm. The precipitation bucket was clean.

Camilo cleaned flux and rad sensors. Joe and I downloaded met, camera, USB, and miniDOT data. The PRI_in data was NAN the past few days but restarted again earlier today before we arrived at the site. The 7500 and 7700 clocks looked ok. I changed the 7700 wash spin from 10 sec to 30 sec to allow enough time to spin away the spray water (7700 wash spray remained at 10 sec). Joe swapped desiccants for the miniDOT and the water level sensor. The wash reservoir was empty; we refilled it.

LI-7500 readings:
CO2 537ppm
H2O -164ppm-->390 after cleaning
T 12.2C
P 101.9kPa
SS 20--> 99 after cleaning
LI7700 readings:
CH4 2.7 ppm
RSSI 43--> 86 after cleaning

We left at 15:40 PST.
