Bouldin Alfalfa

Mike and I arrived at 15:45 PDT. It was a warm and windy spring day -- the perfect allergy trifecta. This is our 7th week of sheltering in place, with at least 4 more weeks to go. There were generally many tractors rumbling about on the dirt roads. Our field has been mowed, and there was a raker parked on our field. They were currently baling the field to our east. I took some videos and photos with a 360 camera.

I downloaded met, camera, USB GHG, and both FD chambers. I cleared the FD chambers after the download. The reservoir was 20% empty; I refilled it. I cleaned flux and rad sensors and the camera window. I took vegetation height measurements but forgot spectral.

I checked the eddy and phenocam clocks. The eddy clocks looked good. I changed the phenocam clock from 14:59 to 15:14 to match the laptop time.

LI-7500 readings:
CO2 412ppm
H2O 323ppm
T 28.1C
P 101.6kPa
SS 97--> 98 after cleaning
LI7700 readings:

RSSI 34-->72 after cleaning

We left at 16:20 PDT.
