Summary: Picarro / Forerunner chamber experiment field measurements, fixed HMP45 fan

I arrived about 11am with Ryan from Whendeeâ€™s lab. It was super hot with very little breeze.

Ryan did syringe samples from three static chambers.

I did the LI6400 soil chamber measurements. I worked the soil collars from west to east and redid number two at the end because I think I interrupted the measurement the first time. There are two files on the LI6400: SI_20140630 is a false start. SI2_20140630 should be good.

I also ran ultra zero air, Scotty N2O, and Ameriflux standard gasses through the Picarro. The Ameriflux standard has 1.9645 +- 0.002ppm CH4, 456.55 +- 0.02ppm CO2

12:13 to 12:20 ultra zero air: 0.007 N2O, 0.038 CH4, 8.804 CO2
12:21 to 12:28 1ppm N2O: 0.998 N2O
12:28 to 12:36 Ameriflux: 2.001 CH4, 472.53 CO2

I copied the raw Picarro files to usb, but the Forerunner software was too slow to download, so I left it processing and thought we could get it over the internet.

I also replaced the fan in the HMP45 on the tower and collected the Vaisala soil co2 and met data.
