Moisture Controls on Trace Gas Fluxes in Semiarid Riparian Soils
Variability in seasonal soil moisture (SM) and temperature (T) can alter ecosystem/atmosphere exchange of the trace gases carbon dioxide (CO2), nitrous oxide (N2O), and methane (CH4). This study reports the impact of year-round SM status on trace gas fluxes in three semiarid vegetation zones, mesquite (30 g organic C kg soil), open/ forb (6 g organic C kg soil), and sacaton (18 g organic C kg s...

متن کاملSimplified method for quantifying theoretical underestimation of chamber-based trace gas fluxes.
Closed chambers used to measure soil-atmosphere exchange of trace gases including nitrous oxide (N(2)O) and carbon dioxide (CO(2)) generate errors due to suppression of the gas concentration gradient at the soil-atmosphere interface. A method is described here for estimating the magnitude of flux underestimation arising from chamber deployment. The technique is based on previously established g...
