Bouldin Alfalfa

Dennis, Arman, and I arrived at 14:10 PDT. Today was Arman’s first visit to the Delta and it was sunny and breezy. Since our last visit, the alfalfa has been mowed, raked, and baled. Most of the bales had been removed but there were still a few on the western edge of our field. The alfalfa is still very short, <5-10cm tall.

Dennis and Arman took jaz spectral measurements and trimmed the alfalfa under the tower. Dennis noted that it was a clear day, "perfect conditions" for spectral measurements. However, back in the lab there were no new files on the storage card. Maybe the card was not properly in its slot.

I downloaded met, cam, USB GHG, FD, and IRT data. I cleaned flux and rad sensors—the incoming SWin/LWin were both dirty.

The 7500 read: 415ppm CO2, 383mmol/m3 H2O, 19.7C, 101.7kPa, 99.7SS after cleaning

We left at 14:40 PDT.
