Field report

Weather: overcast, diffuse light. Temperatures are lower than in prior weels. It had rained during the weekend and there are paddies on the road.

 

Angèlica refilled the water bucket, which was almost empty.

We cleaned the sensors. There were a lot of baby dragonflies trapped in spiderwebs. Angèlica cleaned the rain bucket too-> fake rain.

We downloaded met data. Note there is the biomet and met30 files starting on oct30. Will need to merge with the buckup.

We downloaded flux data. Deleted smartflux onboard data. This caused that the pc could not connect to the sensors for a while. After re-connecting the cables and restarting the software a few times, it worked again.

We checked the clocks: Datalogger 2s ahead of pc-> set clock. Flux sensor behind pc (only 1/10 of a second), but flux sensor follow utc online.

We checked the poles dimensions for the phenocam setting.

We left the tower at 11.36h utc.
