Summary: Regular data collection/cleaning, installed RPi cam for intercomparison

Mayberry

I arrived at 16:50 PDT. It was warm and breezy. There were a few sprinkles of rain a few days ago on Sunday, but that might be the last of the rain for this season. The wetland is looking greener, but still mostly brown. I climbed down and scrubbed the staff gauge, which read 31 cm.

I downloaded met, camera, and USB GHG data. I downloaded FD data and cleared its memory. I cleaned the flux and rad sensors and topped off the wash reservoir. The Rnet sensor over the water had a lot of bird poop on it.

I installed a Raspberry Pi camera to compare with our Canon photos since the Canon photos are occasionally underexposed, although that problem seems to have improved once we changed the canonâ€™s internal battery. I added sn RPI0W-003 to the NW scaffolding post, under the eddy sensors. Itâ€™s pointed approximately west to match the view of the Canon camera.

I left at 17:45 PDT.
