Summary: Standard fieldwork, updated Tower met program to try to fix spikes in reflected PAR.

2020-01-28

Daphne and I arrived at about 11:30. It was mostly overcast with patches of light rain and sun. The ground is wet but not soggy and there are large puddles on the road. The pond level has not come up much though. The grass here is sparser than at Vaira and many of the tips have yellowed â€“ frost damage?

I downloaded data from the towers and other data loggers. At the Tower top I moved the two PAR sensors down two slots on the multiplexer because there have been spikes in the reflected PAR. A new program was loaded. I downloaded the FD chambers and cleared their memories.

I serviced the z-cams. I checked the images on z-cam 1 and it seemed to be working properly. It is now driven by the CR6 controlling the CO2 profile instead of the original CR10x.

Daphne did the soil moisture, manual well measurements, and dendrometers. She also collect some more soil for Miriam and Anaâ€™s emissivity project. However there was a puddle where Ana indicated they got the soil last time so this batch it from a spot a little farther to the west.
