Summary: Installed independent trip pod with radiometers for Delta wide comparison, set 23x met clock, reset camera

Twitchell Rice

I arrived about 3pm. It was mild and mostly sunny. They have set up propane canons and predator bird calls to dissuade the black birds from eating all the rice.

I set up a tripod with five radiometers on a battery powered CR6 data logger sn 2115 for a Delta wide radiometer comparison. The radiometers are

Kipp & Zonen PSQ1 PAR sn 140456 (#1)
Kipp & Zonen PSQ1 PAR sn 140457 (#2)
Licor LI-190/R PAR sn Q100421
Kipp & Zonen CM3 SW sn 060039
Hukseflux NR01 sn 2420 (SW in only)

Of course, this is the only data logger I did not check the clock on.

I check the clock on the rice tower 23x. It was only a couple minutes off and I reset it.

I also checked on the camera. It looked like there were 200 images on it. I reset it and crossed my fingers.
