Summary: Regular data download/cleaning, spectral

2020-06-02
Sherman Barn

I arrived at 14:30 PDT. It was a hot, breezy day with some thin clouds. There were same piles of dried mud east of our tower that Joe had seen last week-- there were some random boot prints in the mud, but now the mud was hard as a rock. The grass is short and mostly green to the north and west of our tower. There is a lot of litter and chewed weed stalks south of the tower. The electric fence was off and there were no cows nearby, so I left it off. Tyler had 1 chamber on care soil inside the exclosure.

I downloaded met, cam, gamecam, and USB GHG data. I reset the gamecam clock. I also took spectral measurements. The reservoir was full; I left it as is. I cleaned the flux and rad sensorsâ€”there were spiderwebs all over the flux sensors and I evicted a spider from the top of the 7700 cap.

LI-7500 readings:
CO2 404ppm
H2O 570ppm
T 33.4C
P 101.5kPa
SS 98--> 101 after cleaning
LI7700 readings:
CH4 1.95ppm
RSSI 30-->72 after cleaning

I left at 14:55.
