Bouldin Corn

We arrived at 10:24. Weather was sunny and mild with thin, wispy clouds and a cool breeze.

Corn is about head height.

Kuno cleaned flux, rad, and Arable sensors, as well as topped off the wash reservoir, which was mostly full.

Alex took vegetation height.

I took handheld LAI measurements. Because the Bouldin Alfalfa LAI file was accidentally named "BC", the Bouldin Corn LAI file was named "BA".

Kuno swapped the 7500 for calibration sn 75H-2668 came down and sn 75H-2182 went up.

Daphne did regular USB, met, and cam data collection as well as uploaded new config file, updated pressure coefficients, reset the 7550 box and confirmed that USB was logging and that 7700 was connected.

We left at 10:55.
