Kyle, Kuno, and I arrived at 15:00. There was some blue sky, with big clouds and light wind. The field is partly flooded, especially the southern end near the tower and the northern end near the highway. It has been raining in the past few days and a large storm is expected later that night. There were three white pickup trucks parked by the Duck Club and some bbq grills set up on the patio.

I collected met, camera, and USB GHG data. The mux-datalogger wiring looked secure and there wasnâ€™t any missing data in the past month, so Iâ€™m not sure what the problem was in October. Kuno cleaned flux and rad sensors. Wash reservoir was mostly empty, but we only filled the wash reservoir 2/3 full to save DI water for BA.

CO2 416ppm
H2O 707ppm
T 16.9C
P 100.3kPa

LI7700 readings:

We left at 15:10.
