Summary: Regular data collection/cleaning, windy, cows and weeds by our tower, reset 7550 box

Sherman Barn

Mike and I arrived at 10:10 PDT. It was a warm day but with a strong, cool breeze. The skies were clear. There are still cows on our field. The weeds by the tower seem a little more grazed than last week. There was no water in the well. I took some videos and photos with a 360 camera. This is our 7th week of sheltering in place, with at least 4 more weeks to go.

I downloaded met, camera, USB GHG, and game camera data. The wash reservoir was mostly full; I topped it off. I reset the 7550 box because there was a flickering time sync error. The error went away. I changed the phenocam clock slightly from 9:41 to 9:42 PST to match the laptop time. I fixed the 7700 wash tubing by snipping off the degraded section and attaching it again with a small ziptie. I took spectral measurements.

LI-7500 readings:
CO2 422ppm
H2O 300ppm
T 20.1C
P 101.8kPa
SS 100--> 101 after cleaning
LI7700 readings:
CH4 2.01ppm
RSSI 34-->78 after cleaning

We left at 10:55 PDT.
