Characterizing spatial and temporal variations in CO2 fluxes from ground surface using three complimentary measurement techniques

Fluxes of CO2 from non-agricultural soil ecosystems, though globally important, are poorly characterized. Previously, we tested a dynamic closed chamber (DCC) method that was shown to accurately measure CO2 fluxes from ground surface to the atmosphere in mesocosms. In the current study, the DCC method was used to measure the CO2 efflux at a field site where conditions were similar to those used in the mesocosm tests. Fluxes measurements also …
