We arrived about 13:00 PDT. Warm with a nice breeze. High sparse clouds. I did tower maintenance while Dennis and Patty did spectral and veg height. Still lots of weeds in the field.

The camera was off and the card had only one photo. I put new batteries into the camera and started the program.

CO2 = 370 ppm (375 after cleaning)
H2O = 870 mmol m-3 (815 after cleaning)

t = 28.5 C
sos: 351.8 m s-1

7700 readings:

Met looked good.
Cleaned rad. The LED was covered in bird poop.
