Twitchell Alfalfa: 2017-01-06 14:00:00 (DOY 6)

Summary: Moved longwave channels and updated CR1000 met program

Twitchell Alfalfa
2017-01-06

I arrived about 2pm with Dennis and Siyan. The ground is very wet and the road along the south edge of the field is muddy. We ended up driving on the alfalfa just north of the road most of the way. The field is almost bare after grazing by the sheep. There are lots of squirrel mounds.

Yesterday, Sam swapped the longwave channels and decided that port 6 on the AM16/32 multiplexer was bad. We swapped the longwave channels back and moved them to ports 11 and 12 on the multiplexer. I updated the CR1000 program to reflect the new channels. All looked well.

The rotating shadow band was not moving. I opened the box and banged on the motor a bit. It started moving again, but probably needs to be replaced next time.
