Twitchell Alfalfa
2014-07-23

We arrived just after 14:00 PDT. It was sunny and warm with a nice breeze from the West. Kathleen did veg height while Patty and I attended to the tower. We noticed that the camera had lost power. When we first checked the connector there was no power running to the camera. Patty fidgeted with the connector and eventually got power running to the camera but it still wouldn’t turn on. We need to try to fix this next week. I downloaded the flux data and checked the met data, but realized I had left the USB to serial adapter at Mayberry so I wasn’t able to download the met data (I did go back and get the USB adapter and we returned to the site at 16:45 PDT to collect the met and radiation data).

7500 readings:
CO2 = 373 ppm
H2O = 809 mmol m-3
signal strength = 84%
p = 101.75 kPa
t = 28.8 C
sos = 350.0 m s-1

Met seemed good.
Radiation good.
