Summary: Regular data collection/cleaning, Removed HMP60 for field test

Sherman Wetland

We arrived at 9:25. It was cool, calm, and clear, but hazy at the horizon. There was a recent and rather large fire in the fields east of Hwy 160 and the first couple of fields along the dirt road. Spots were still smoking when we arrived. New fencing going up in those same fields.

I collected met, camera, and USB GHG data. Dennis refilled the reservoir; it was empty. Sam removed the HMP60 sn L2310736 to move to TA for the HMP field test. We cleaned the flux/rad sensors.

LI-7500 readings:
CO2 428 ppm --> 442 after cleaning
H2O 340 mmol/m3 --> 320 after cleaning
T 9.6 C
P 102.5 kPa
SS 91.5 --> 98 after cleaning

LI7700 readings:
CH4 2.1 ppm --> 2.5 after cleaning
RSSI 46 --> 76 after cleaning

We left at 9:40.
