Bouldin Alfalfa: 2018-05-31 10:50:00 (DOY 151)

Summary: Regular data collection/cleaning, LAI, clip plots, veg height, field mowed

2018-05-31
Bouldin Alfalfa

We arrived at 10:50. It was warm, breezy, and hazy. The field has been mowed but not baled.

Katrina took LAI measurements. The initial “below” measurement file, “BA0531” didn’t work, so she took a second “below” file, “BA0531B.” Alex collected biomass samples and measured veg height.

I collect met, camera, and USB GHG data. Alex cleaned the rad sensors and refilled the wash reservoir. I cleaned the flux sensors. The 7500 didn’t look obviously dirty, even though SS was 0 and initial CO2/H2O were out of range.

LI-7500 readings:
CO2 ***ppm --> 416 after cleaning
H2O ***ppm --> 425 after cleaning
T 18.6C --> 20.6 after cleaning
P 101.3kPa --> 101.4 after cleaning
SS 0 --> 112 after cleaning

LI7700 readings
CH4 2.0ppm
RSSI 55 --> 72 after cleaning

We left at 11:45.

After coming back from the field, I saw that CO2/H2O flux data had been out since 2018-05-19 evening. I didn't see anything obvious (spraying, tractor work) in the phenocam photos.
