Summary: Cows in footprint, normal data collection and spectral measurements

Arrived at 3:10pm. Sky pretty clear by this point, no wind. Just pepperweed sticks and baby green grass present—no need for veg height. The cows were in the footprint of the tower, watching Sara closely as she took spectral. Joe collected data and pulled a couple rods out of the ground where the soil systems used to be. I cleaned a rodent head out of the rain gauge and cleaned the camera window and 7500.

The 7500 read: 17.47mmol/m3 CO2, 497.8mmol/m3 H2O, 102.1kPa, 20.9C, 248diag
The LGR read: 15:29, 22.31C, 113.6Torr, 14.739usec, 10Hz, 2.176ppm CH4
I had to turn the bypass valve a bunch to get pressure to 142.5Torr

The CFM card took a long time to format - maybe time to retire.
