Retrieval of atmospheric CO2 from satellite near-infrared nadir spectra in the frame of ESA's climate change initiative — •Maximilian Reuter, Michael Buchwitz, Oliver Schneising, Jens Heymann, Heinrich Bovensmann, and John Burrows — Institute of Environmental Physics, University of Bremen, Germany

ESA's climate change initiative (CCI) aims at global satellite measurements of essential climate variables (ECV). One of these variables is XCO2 (the column-average dry-air mole fraction of atmospheric CO2) which is retrieved from the satellite instruments SCIAMACHY aboard ENVISAT and TANSO aboard GOSAT. Results of the SCIAMACHY retrieval algorithms WFM-DOAS and BESD will be the focus of the presentation. This includes a comparison against ground based FTS measurements, GOSAT retrievals, and model results.
