East End

Ariane and I arrived at 10:35 PST. It was a sunny and mild day with clear skies and haze at the horizons. There might be a little rain late next week. The water level has gone down a little--the staff gauge read 29cm. The wetland is about 40% green.

I downloaded met, camera, USB GHG, and miniDOT data. I swapped desiccant for the water level sensor and miniDOT. Ari cleaned flux and rad sensors. The lower 7700 mirror was pretty dusty. The wash reservoir was empty; we refilled it.

LI-7500 readings:
CO2 400ppm
H2O 540ppm
T 22.1C
P 101.7kPa
SS 94 --> 101 after cleaning
LI7700 readings:
CH4 1.0ppm --> 2.0 after cleaning
RSSI 0 --> 82 after cleaning

We left at 11:00 PST. I brought one of the old batteries back to the lab and left it downstairs.
