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. The emission fluxes of CH4 and N2O from paddy rice fields were measured using methods based on static opaque-chamber and gas chromatography techniques.
2012-01-16 · Aside from water vapour, the four principal greenhouse gases are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) and the halocarbons or CFCs (gases containing fluorine, chlorine and bromine).

The 100-year GWP is used to derive CO 2 e. Nitrogen composition effects on CO2 emissions and CH4 uptake were independent of N input rates and measurement dates, but N2O emissions showed stronger responses to inorganic N under high N Total Emissions in 2018 = 6,677 Million Metric Tons of CO 2 equivalent.Percentages may not add up to 100% due to independent rounding. Larger image to save or print Gases that trap heat in the atmosphere are called greenhouse gases. This section provides information on emissions and removals of the main greenhouse gases to and from the atmosphere. These measurements show that the concentration of the three most important greenhouse gases (other than water vapour) CO 2, CH 4 and N 2 O have steadily increased during the past 250 years due to anthropogenic activities ( Prather and others, 2001; Prentice and others, 2001 ). 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.
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.

For CO2 concentrations, an open-path infrared gas analyzer was used, while N2O and CH4 concentrations were measured with a recently developed continuous-wave quantum cascade laser absorption spectrometer (QCLAS). The green-house gases include CO2, CH4, N2O, HFCs, PFCs and SF6. The figure shows the estimated total greenhouse gas emissions in CO2 equiva-lents from 1990 to 2004.

Greenhouse gases consist of Carbon dioxide (CO2), Methane (CH4), Nitrous oxide. (N2O), Ozone (O3), and Chlorofluorocarbons (CFCs).
Citing Literature The Earth has a natural greenhouse effect due to trace amounts of water vapour (H 2 O), carbon dioxide (CO 2), methane (CH 4) and nitrous oxide (N 2 O) in the atmosphere. Here we present evidence that the soils under alpine and sub-alpine snowpacks emit CO 2 and N 2 O and take up atmospheric CH 4 throughout the snow-covered period.
