Meanwhile, CO2 fluxes was obviously correlated with the CH4 emission fluxes (R2 = 0.751, p < 0.001). The mires are N2O sink in winter and gradually become N2O source, with increasing temperature during thawing time. Cerrado appeared to be a minor source of N 2 O and a sink for atmospheric CH 4. Burning also elevated CO 2 fluxes, which remained detectably elevated 1 year later.

EDGAR aims to inform scientists and policy makers on the evolution of the emission inventories over time for all world countries and to provide the scientific community 0.1degX0.1deg gridmaps representing the emissions sources. 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 CH4, N2O, NO, and CO2 fluxes from improved fallows of Inga edulis and Acacia mangium during two successive fallow periods in an old agricultural frontier on sandy soils in eastern Amazonia. 2021-03-30 Ice core records of the major atmospheric greenhouse gases (CO2, CH4, N2O) and their isotopologues covering recent centuries provide evidence of biogeochemical variations during the Late Holocene and pre-industrial periods and over the transition to the industrial period. 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. Northern peatlands are important carbon (C) reservoirs, storing about one-third of the global terrestrial soil C pool. Anthropogenic influences, such as drainage for agriculture and forestry, lower the originally high groundwater level, leading to peat aeration and decomposition.

Emissions of CO2, CH4, N2O, HFC, PFC, FS6 Vol 2009 release 01 - Notice.

Carbon dioxide (CO 2), methane (CH 4) and nitrous oxide (N 2 O) are key radiatively active greenhouse gases (GHGs) contributing to global warming (IPCC, 2001). The production and emission of these greenhouse gases have increased continuously since the pre-industrial era.

Besides agricultural soils, temperate forest soils have been identified as significant sources of or sinks for important atmospheric trace gases (N2O, NO, CH4, and CO2). Although the number of studies for this ecosystem type increased more than tenfold during the last decade, studies covering an entire year and spanning more than 1-2 yr remained scarce. This study reports the results of

A method for determination of the climate gases CH4, CO2 and N2O in air samples and soil atmosphere was developed using GC-MS. The method uses 9 Jan 2019 other C cycling processes and may emit N2O, CH4 and CO2 as well. of CH4 and has no effect on CO2 emissions from wetland sediments.
