Summary: Regular data collection/cleaning, dead cow on field

Sherman Barn

Camilo, Ariane, and I arrived at 14:40 PDT. It was a warm and sunny day with blue skies and a gentle breeze. The weeds east of the tower are much shorter than I remember. There was a dead cow N of the tower, too far for us to see clearly, but we could see the vultures hanging out and circling around it. Camilo went to go look at the pond N of the tower; it was wet and about 130 m from the exclosure.

Ariane took spectral measurements. Camilo cleaned flux and rad sensors. I downloaded met, USB GHG, cam, and game cam data; I had to reset the game cam clock. There were some spikes in AirT. The wiring looked ok, so Iâ€™ll keep an eye on it. I added a desiccant tube to the water level sensor. The wash reservoir was 90% full; we refilled it.
