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

2020-05-05
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. It’s been a drier winter, and there hasn’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.
