We arrived around 09:30 PDT with Deb Agarwal, Marilyn Saarni, Rachel Hollowgrass, Cristina Poindexter, Gilberto Pastorello, and Olaf Menzer from Ameriflux. They came out to see what we do in the field and get ideas to make submitting BADM data easier. It was sunny, windy, and cool. The vegetation stature at the site has certainly dropped as most of the pepperweed has senesced and been cow-trampled. There are still patches of a green understory, however. I attended to the tower, did moisture point, and well depth while Patty and others did LAI, spectral, and veg height. Cristina collected some instrument positions relative to the flux tower for the BADM.
