Abstract We evaluated the spatial structures of nitrous oxide (N2O), carbon dioxide (CO2), and methane (CH4) fluxes in an Acacia mangium plantation stand in Sumatra, Indonesia, in drier (August) and wetter (March) seasons. A 60 × 100-m plot was established in an A. mangium plantation that included different topographical elements of the upper plateau, lower plateau, upper slope and foot slope. Soil N2O, CH4, and CO2 fluxes were measured with dark chambers from May 2011 to November 2014.
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.

The average diffusivity of CO2, CH4 and N2O in MOF-5 and MOF-177 is in the order of 10−9 m2/s, as compared to 10−11 m2/s for CO2, CH4 and N2O in zeolite 5A. 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 straightforward gas chromatography (separation of the gases) with a mass spectrometric detector in single ion mode (specific determination).

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.

Methane’s 100-year GWP is about 28x CO2 – but it only persists in the atmosphere for a little more than a decade. The 100-year GWP is used to derive CO 2 e.
