Left: Mitchell Richardson setting up the automated GHG sampling system. A component of the sampling system is an SRI gas chromatograph for gas concentration measurements integrated with a Campbell Scientific Data Logger to control sampling equipment. Right: Here Richardson is shown maintaining GHG sampling equipment at the field sampling site. On his left is a LI-COR flux gas chamber with orange flags to mark the location of the soil gas samplers along with the trailer housing the GHG sampling system.
