Summary: Regular data collection/cleaning, tall and flowering weeds, first site visit in a month

2020-04-03
Sherman Barn

Mike and I arrived at 15:20 PDT. It was a sunny and mostly clear day but breezy and cool. The grass and weeds are green, tall, and flowering in the pasture. It has been dry recently, but itâ€™s expected to rain for 3 days starting tomorrow. This is the first site visit in a month. The Bay Area is on the third week of COVID-19 shelter-in-place orders, with at least 4 more weeks to go.

I downloaded met, camera, USB GHG, and game camera data. The wash reservoir was 4/5 empty; we refilled it. I cleaned flux and rad sensors. I tested the spray/spin, which seemed fine. There was some earwigs in the datalogger box, but no mothballs in the blue bag.

LI-7500 readings:
CO2 406ppm
H2O 270ppm
T 20.2C
P 101.7kPa
SS 98--> 101 after cleaning
LI7700 readings:
CH4 1.96ppm
RSSI 27-->73 after cleaning

We left at 15:45 PDT.
