Summary: Ewes/lambs on our field, spectral measurements, trimmed alfalfa under tower

Bouldin Alfalfa

Joe and I arrived around 10:15 PST. It was a sunny and cool morning with hazy horizons. There were many strings of geese in the air. The main flock of sheep are still 2 fields to our east, but the ewes/lambs have been moved closer to our tower.

We trimmed the alfalfa in our exclosure and cleaned the solar panels.

Joe took spectral measurements in grazed, half-grazed and ungrazed areas of the field and cleaned flux and rad sensors.

I downloaded met, cam, and USB GHG data. The eddy clock looked ok. I changed the phenocam clock from 10:45 to 10:48. Looking at the data back in the lab, there are no camera photos after Dec 6. Iâ€™ll keep an eye on it.

LI-7500 readings:
CO2 450ppm
H2O 390ppm
T 12.4C
P 102.0kPa
SS 97--> 102 after cleaning
LI7700 readings:
CH4 2.5 ppm
RSSI 50-->71 after cleaning

We left around 11:30 PST.
