Summary: Regular data download/cleaning, installed new AirT/RH HMP sensor

Sherman Barn

Joe and I arrived at 10:55 PST. It was a clear and cold day with blue skies. The grass is short and green, and there were cows around our tower. Tyler was here checking on his chambers. He had recently installed a UPS that would tide his system over 15-min power blips, and was happy to report a whole week of continuous data.

Joe downloaded met, USB GHG, and gamecam data and reset the gamecam clock. I cleaned flux and rad sensors. The wash reservoir was mostly full; I topped it off. We installed an AirT/RH sensor (HMP45C sn T2130005); the previous one was removed a few weeks ago because the AirT was reading too low. We swapped the water level desiccant. I took spectral measurements.

LI-7500 readings:
CO2 417ppm
H2O 395ppm
T 10.2C
P 103.1kPa
SS 100--> (forgot to write after cleaning)
LI7700 readings:
CH4 2.1ppm
RSSI 42-->77 after cleaning

We left at 11:25 PST. We came back at 13:35 PST to swap the camera card.

Back in the lab, we couldn't find the SW GHG data, so it's probably on this USB stick.
