2014-01-01 The three major trace gases, carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) were measured with the eddy covariance (EC) technique. For CO2 concentrations, an open-p … The first full greenhouse gas (GHG) flux budget of an intensively managed grassland in Switzerland (Chamau) is … The fractions 44/12, 16/12 and 44/28 were used to convert the mass of CO 2 ‐C, CH 4 ‐C and N 2 O‐N into CO 2, CH 4 and N 2 O. RF CH4 and RF N2O are constants indicating radiative forcing of CH 4 and N 2 O in terms of a CO 2 equivalent unit, and were assigned values of 25 and 298, respectively, at 100 year time horizon [Forster et al., 2007]. Because of the limited amount of air available, a semi-automated procedure is used to inject the small volume of ice core air into the GC inlet systems. Approximately 15–20 mL is used to measure CO2, CH4, CO, and H2, and 12–15 mL is used to measure N2O. The remaining air (typically 40 mL) is used for δ13C and δ18O measurements.

Decadal variations during the industrial period include the stabilization of CO 2 and slowing of CH 4 and N 2 O growth in the 1940s and 1950s. To contribute towards an improvement of actual estimates, soil‐atmospheric CO 2, CH 4, and N 2 O fluxes were measured in three successional subtropical forests at the Dinghushan Nature Reserve (hereafter referred to as DNR) in southern China. Soils in DNR forests behaved as N 2 O sources and CH 4 sinks.

To study the feedback effect of greenhouse gases on climate change in permafrost regions, emissions of CO2, CH4, and N2O were continuously measured by using the static chamber-gas chromatograph method, in three forest soil ecosystems (Larix North American terrestrial CO2 uptake largely offset by CH4 and N2O emissions: toward a full accounting of the greenhouse gas budget Hanqin Tian & Guangsheng Chen & Chaoqun Lu & Xiaofeng Xu & Daniel J.

Variations in N 2 O were modest and concentrations fluctuated around atmospheric equilibrium, so data are presented as percent of saturation level (% N 2 O, where atmospheric equilibrium corresponds to 100 %), computed from the global mean N 2 O air mixing ratios given by the Global Monitoring Division (GMD) of the Earth System Research Laboratory (ESRL) of the National Oceanic and Atmospheric
