Bouldin Alfalfa: 2019-02-12 13:20:00 (DOY 43)

Summary: Regular data collection/cleaning, sheep did a good job mowing alfalfa, tried to upgrade 7700 firmware - comm error

Bouldin Alfalfa

Kuno, Camilo, and I arrived at 13:20. It was cloudy, cold, and breezy. The sheep did a good job grazing the alfalfa—most of the plants are trimmed down to the soil.

I downloaded met, FD, and USB GHG data (forgot to swap camera card). The wash reservoir was 1/3 empty; we refilled it. Camilo cleaned flux and rad sensors. I tried upgrading the 7700 firmware for sn TG1-0421 from 1.0.23 to 1.0.27, but during the initial file transfer step there was an error, “Fatal: Network Error: Connection Timed out.” We tried swapping for a different USB stick, but got the same error.

LI-7500 readings:
CO2 410ppm
H2O 306ppm
T 9.8C
P 101.6kPa
SS 98-->99 after cleaning

LI7700 readings:
CH4 2.4ppm
RSSI 48 --> 82 after cleaning

We left at 14:00.

Next Mowing: 2019-04-29
