Summary: Reinstalled FD chamber, field just mowed

2017-09-21
Twitchell Alfalfa

We arrived at 8:30 on our way to Tonzi/Vaira. It was partly cloudy, breezy, and cold.

Our footprint has been mowed and they were mowing east of the tower (in the ditch) when we arrived. It doesn't look like there was much to mow; the alfalfa piles are so small it was hard to see them against the remaining plants.

We tested the FD chamber yesterday in the lab and it was recording data consistently, even though some of the data were 0.

Joe and I re-installed the FD chamber sn FD20160001 in its original location. Joe connected the FD power to a power supply at 12.4V. The chamber was buzzing when we left around 8:50.
