Summary: Regular data collection/cleaning, cows on pasture

2019-04-03
Sherman Barn

Kyle, Camilo, and I arrived at 13:15. It was mostly overcast and mild, with intermittent sun. We finally have cows on our pasture, and we can see more signal from the motion sensor starting around 2019-03-20. The grass is still green and beautiful, but there are many more weeds in the pasture than 3 weeks ago.

Kyle took spectral measurements and cleaned flux and rad measurements. I collected met, camera, and USB GHG data. There are still gaps in SWin, even after trying to switch the channels with SWout last time. I could try moving the channels again, but it could be a sensor issue. I also downloaded the photos from the Bushnell game camera. The game camera clock was 2011-1-1 00:00:00 and I reset it to 2019-04-03 12:35 (PST time zone). The wash reservoir was empty; we refilled it. Camilo checked the Picarro box, which was dry. Camilo also removed some weeds inside the enclosure. The Nikon camera was out of batteries so we did not take a reference GCC photo.
