Abstract

The column-average dry air mole fractions of atmospheric carbon dioxideand methane and are inferred from observations of backscatteredsunlight conducted by the Greenhouse gases Observing SATellite (GOSAT).Comparing the first year of GOSAT retrievals over land with colocatedground-based observations of the Total Carbon Column Observing Network(TCCON), we find an average difference (bias) of −0.05 and −0.30for and with a station-to-station variability (standard deviationof the bias) of 0.37 and 0.26 among the 6 considered TCCON sites.The root-mean square deviation of the bias-corrected satellite retrievalsfrom colocated TCCON observations amounts to 2.8 ppm for and 0.015ppm for Without any data averaging, the GOSAT records reproducegeneral source/sink patterns such as the seasonal cycle of suggestingthe use of the satellite retrievals for constraining surface fluxes.
