Summary: Standard field work & data download. All well.

Twitchell Alfalfa
2014-05-01

Sara and I arrived about 13:15 PDT. It was hot and sunny with a nice breeze. Alfalfa flowering.

I downloaded data and cleaned the flux instruments. Then I did spectral measurements. Sara did LAI, clip plots, and a veg height survey. We forgot the clipboard over at West Pond so I didn’t record any measurements, but all was fine.

Flux ok.
Cleaned radiation sensors.
Met ok. Rad ok.

The camera was off.

Veg Height (cm): Tape measure from ground to top of plant
64, 52, 60, 58, 57, 59, 48, 54, 46, 42, 54, 51, 68, 58, 54, 46, 57, 46, 58, 32, avg = 53.2, stdev = 8.21
