Bouldin Alfalfa

Camilo, Katrina, and I arrived at 13:50. It was sunny and hot, with mostly clear skies. The alfalfa was mowed on 2019-07-24, but had not baled yet. The mowed piles were crispy. There were generous amounts of bird poop on the instruments and on the tower. Camilo trimmed uncut alfalfa under the tower, but left the alfalfa under the tower (trimmed at last visit) for potential LI-6400 measurements.

Katrina cleaned flux sensors and Arable sensor/solar panels. Camilo cleaned rad sensors and knocked down a palm-sized wasps nest under the radiation boom. He tried to take spectral measurements, but the reference measurement was oversaturatedâ€”I need to see if we can correct this for next time. I collected met, camera, USB, and FD data. The wash reservoir was mostly empty; I refilled it.

LI-7500 readings:
CO2 396ppm
H2O 696ppm
T 31.8C
P 101.5kPa
SS 98--> 100 after cleaning
LI7700 readings:
CH4 1.78ppm
RSSI 2-->73 after cleaning

We left at 14:30.

Next Mowing: 2019-08-14
