CO2 and N2O concentrations decreased during storage depending upon septa type and initial concentration, with the highest linear rate being 0.023 for CO2 and 0.0015 mg L(-3) day(-1) for N2O. In 1992 we measured soil fluxes of NO, N 2 O, CH 4, and CO 2 from cerrado sites that had been burned within the previous 2 days, 30 days, 1 year, and from a control site last burned in 1976. NO and N 2 O fluxes responded dramatically to fire with the highest fluxes observed from newly burned soils after addition of water. 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. 2021-02-01 · This study strengthens the evidence by investigating the spatial variability of diffusive GHG (N 2 O, CH 4, CO 2) emissions from river reaches that drain from different types of landscapes (i.e., urban, agricultural, mixed, and forest landscapes), in the Chaohu Lake basin of eastern China.

Anthropogenic influences, such as drainage for agriculture and forestry, lower the originally high groundwater level, leading to peat aeration and decomposition. This is particularly reflected in significant losses of CO2, while fluxes of N2O and CH4 are generally considered Major increases in CO 2, CH 4 and N 2 O concentrations during the past 200 years followed a period of relative stability beforehand. 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. Effects of elevated atmospheric CO2 on CH4 and N2O emissions during the paddy rice-growing season were examined in a FACE (free-air carbon dioxide enrichment) study.

Data herein are presented for global-warming potentials of 25 g-CO2e/g for CH4 and 298 g-CO2e/g for N2O. Perhaps the most critical observation from the US-EIA data is that it is so coarse that only two domestic-wastewater Scope-1 GHG sources and electricity-related Scope-2 CO2 are included, specifically: 16 Sep 2013 Greenhouse gases (CH4, CO2 and N2O) emissions from a newly flooded hydroelectric reservoir in subtropical South Asia: case of Nam Theun The greenhouse gases reported under the Climate Convention are: Carbon dioxide (CO2); Methane (CH4); Nitrous Oxide (N2O); Hydrofluorocarbons (HFCs) The objective of this study was to evaluate the effect of leguminous fallows on ethane (CH4), carbon dioxide (CO2), N oxides (N2O and NO) fluxes.We measured Description.
