Sherman Barn

Kyle, Kuno, and I arrived at 9:20. It was foggy and cool, although occasionally it was sunny enough to make distinct shadows. The field had pools of water on the eastern edge. It has been raining in the past few days and a large storm is expected later that night. The weeds in the exclosure have died down in the past month.

I downloaded met, camera, and USB GHG data. There were some ants in the met box so I left a mothball in. Kyle cleaned the flux and rad sensors. The wash reservoir was 2/3 full; we refilled it.

LI-7500 readings:
CO2 467ppm
H2O 667ppm
T 13.8C
P 101.4kPa
SS 102--> 103 after cleaning

LI7700 readings:
CH4 2.9ppm --> 2.8 after cleaning
RSSI 1.3--> 73 after cleaning

There was a small pool of water in Kunoâ€™s Picarro box, and there were also some water condensed in the inlet tubes. We left Kuno at the site at 9:40 to clear out the box and the tubing while we went to service SW and MB.

The following day, 2018-09-28, Kuno and Tyler went back to the site to check on the Picarro. The inlet filter was full of water, so theyâ€™re running box air through the Picarro for now to try to dry it out. They will go back on Monday to check on it.

We came back around 11:45 to pick him up.
