Summary: Regular data collection/cleaning, sheep/lambs right around the tower, Arable Mark tilted--fixed

2020-12-16
Bouldin Alfalfa

I arrived at 15:25 PST. It was an overcast and cool day. There were ewes and lambs (and their guard dog) right around the tower when I arrived. The dog barked diligently , backing itself and the sheep away from the tower, until the shepherd approached on his ATV.

I downloaded met, camera, and USB GHG data. I re-used the same camera card since we might be having problems with the other card and the next site visit will be in 3 weeks after winter break. I downloaded and cleared the FD chamber. I cleaned the flux and rad sensors. The older Arable Mark (with the black rim) was tilting at an angle, so I straightened it. The reservoir was 10% empty; I refilled it. I skipped spectral because it was getting late.

LI-7500 readings:
CO2 470ppm
H2O 490ppm
T 13.4C
P 102.1kPa
SS 99--> 100 after cleaning
LI7700 readings:
CH4 2.8 ppm
RSSI 47-->73 after cleaning

I left at 15:40 PST. By this time the sheep had backed up all the way south to the levee road. The lambs were running in a pack in a circle.
