Bouldin Alfalfa

Joe and I arrived at 16:05 PDT. It’s only been a week since the last site visit but I will be away all next week. It was warm and sunny with an occasional breeze. We took the back way here and saw corn fields in all states--harvested, partly harvested, and some field with immature plants without cobs. The alfalfa is about knee high and flowering, but sparser than the beginning of the season. I don’t think they’ll harvest in the next two weeks—too busy harvesting corn.

We used datamule to download the latest NIKIRA data. The first download try failed because the laptop ran out of space. After deleting some of the older NIKIRA data, we were able to complete the download. Brian is planning to come out next week to remove the sensor since there’s enough data now for an inter-comparison.

I downloaded met, cam, USB GHG, FD, and IRT data. Joe cleaned flux and rad sensors and took veg height and spectral data.

Joe removed the PL Arable sn C011018 since their inter-comparison project is “on pause.”

Joe did veg height and and spectral measurements.

The 7500 read: 413ppm CO2, 605mmol/m3 H2O, 30.1C, 101.0kPa, 97SS--99 after cleaning

We left at 16:50 PDT.
