Summary: Regular data collection/cleaning, grass about 1/4 brown, walked to pond, cleaned camera window

Vaira

Siyan and I arrived around 10:15 PDT in our separate cars. This is our 8th week of sheltering in place, with at least 3 more weeks to go. It was a warm and sunny day with blue skies, a little breeze, and a clear view of the Sierras. The grass is starting to turn brown already. Itâ€™s been a drier winter, and there hasnâ€™t been rain since the first weekend in April. The watering hole looked mostly full, though.

Siyan parked by the tower and walked to the pond to download data. I cleaned the radiometers and the camera window, where there were some black spots on the outside of the window. I shook some debris out of the precip bucket.

I downloaded met, GHG, soil CO2, phenocam, and FD data. I did not clear the FD chambers. Siyan took well level and soil moisture measurements. I took jaz spectral measurements and took clip plot samples. We measured veg height. I pulled some of the more egregious weeds in our enclosure.

We left around 12:00 PDT.
