Summary: alfalfa recently cut, normal data collection, alfalfa around instruments already trimmed.

Arrived: 10:40. Alfalfa recently cut, removing the bales today. Sunny, warm, breezy, mostly clear sky: no clouds but a bit hazy.

Collected USB GHG data; collected camera data; collected met data from CR1000; collected rad data from CR10X; collected camera card: swapped CF card â€œTAâ€ in and â€œTAâ€ out; collected soil CO2.

Did soil respiration, spectral, and cleaned solar panels. Did not do veg height or clip plots because the alfalfa was just cut.

The vegetation around the met instruments had already been cut, probably by the Davis folks who have set up a surface renewal measurement system. Cut veg around solar panels.
