Summary: Regular data collection/cleaning, cold and rainy day after chamber/soil sampling at Gilbert Tract in the morning

2023-12-07
Bouldin Alfalfa

Robert and I arrived at 15:10 PST. It was cold and breezy. There was a rain shower for the first 10 minutes we were there, but then we saw multiple rainbows and a nice view of sunbeams filtering down in front of Mt. Diablo. We are servicing Twitchell/Bouldin Islands after helping with Kuno’s chamber/soil sampling campaign in the first part of the day.

I downloaded met, cam, USB GHG, FD, and IRT data. Robert cleaned flux and rad sensors. I changed the eddy clock +2min to match the laptop time and restarted logging.

The 7500 read: 419ppm CO2, 511mmol/m3 H2O, 13.0C, 102.1kPa, 98SS—forgot to write after cleaning

We left at 15:25 PST.
