Retrieval of tropospheric column-averaged CH4 mole fraction by solar absorption FTIR-spectrometry using N2O as a proxy
International audience Tropospheric column-averaged CH 4 mole fractions were derived from ground-based column absorption measurements. The method uses stratospheric N 2 O columns to correct for the stratospheric contribution to the CH 4 total column. The method was applied to four Total Carbon Colum...
