Summary: Regular data collection/cleaning, alfalfa still short

Bouldin Alfalfa

Joe and I arrived at 15:44 PST. It was partly overcast, cool, and breezy. It rained a bit last night, and more significant rain is forecast for next week. The alfalfa is still short, about 10cm tall. The field just off of the levee road that was plowed last month has some plants coming up; I thought they were planting wheat, but it still looks like raggedy alfalfa.

I downloaded met, cam, USB GHG, FD, and IRT data. I set the eddy clock +1:30 min from 15:47 to 15:48:30 to match the laptop time and restarted logging. I also checked the phenocam clock and changed it -1min from 15:51 to 15:50 to match the laptop time.

Joe cleaned flux and rad sensors and shook out some detritus from the precip bucket. The zPAR sensor was mostly clean but Joe brushed off a few twigs from the sides.

The 7500 read: 413ppm CO2, 528mmol/m3 H2O, 19.7C, 101.3kPa, 98SS—99.5 after cleaning

We left at 16:00 PST.
