Summary: Rain bucket plugged with feathers, Jaz spectral failed - low sun angle?, standard data collection

Vaira

Kuno and I arrived at 15:00 PST. It was mild and sunny with the Valley being very hazy. There was an atmospheric river about two weeks ago and still some small puddles in the low spot near the gate but otherwise still pretty dry. The trees are brown for the most part. Grass has sprouted but still very short. Cows have pounded the area around our site.

I collected the flux, met, FD and camera data.
The 7500 read: 476.5ppm CO2, 444.0mmol/m3 H2O, 21.7C, 100.0kPa, 101.4SS

I cleaned the radiometers and cleaned the bird feathers out of the tipping bucket - looks like the rain data was affected by this.

Kuno measured the well - water level still going down.

I tried to do the Jaz spectral measurements but couldn't get a good reference value. The sun angle was pretty low but should test the Jaz.

We left at about 15:30 PST
