Summary: Standard data collection without camera data. Tower still out of field. Probably seeding rice today.

Arrived at 11:00. Sunny, clear, windy day. The field is dry and looks like it has been recently plowed and prepped for planting, but it does not look like they planted already (we didn't find any seeds in the field). While we were out there, they were filling a seeder close to the field to the north of our tower, so they might be planting later today. Sensors were dusty from the recent tractor work.
Tower is still out of the field.

Filled LI7700 wash water reservoir, was almost empty.
Cleaned radiation sensors.

Collected USB GHG data, collected met data from CR1000. All looks good except SHF(2) is not working (NaN).
We did not collected camera card pictures and did not touch the camera at all. Joe mentioned he needed to sort out some bugs to get the startup of the program going smoothly after shutdown.
