Bouldin Alfalfa: 2019-05-02 10:20:00 (DOY 122)
Author: Daphne Szutu
Others: Alex, Kuno, Ariane

Summary: Regular data download/cleaning, spectral, alfalfa mowed, HMP air temperature bad for a few days

Bouldin Alfalfa

Alex, Kuno, Ariane, and I arrived at 10:20. It was a breezy and sunny day with blue skies. The alfalfa had been mowed (but not baled), and we trimmed the alfalfa under the tower.

Alex took spectral measurements (1-10 cut alfalfa, 11-21 drying hay on field), using putty for the dark reference. Kuno added a bolt to the phenocam mount to prevent it from slipping. I downloaded met, cam, USB GHG, and FD data. Ariane cleaned flux and rad sensors. The wash reservoir was mostly full, so we did not refill it.

LI-7500 readings:
CO2 421ppm
H2O 405ppm
T 20.9C
P 101.6kPa
SS 97--> forgot to write after cleaning
LI7700 readings:
CH4 1.99ppm
RSSI 51--> forgot to write after cleaning

We left at 10:50.

Looking at the data back in the lab, the HMP air temperature data seems too low/suspect starting 2019-04-28. It probably needs to be gap-filled from 2019-04-28 through 2019-05-01. Not sure what caused to it to drift or revert.

Next Mowing: 2019-06-08
