1 WP 3 Satellite observations

2 SCIAMACHY retrieval Month 15: Initial error report Month 18: First dataset for CH4 and CO Incorporation of ECMWF p/T profiles Include gtopo30 surface elevation database to correct for surface pressure Improvements in the applied CO2 model, use optimized CO2 fields (consistent with NOAA CMDL data) Error analysis with special focus on accuracy (e.g., aerosols, surface albedo, fractional cloud cover)

3 Comparison SCIA – FTIR Optimal solution would be to compare CH4/CO2 SCIA with CH4/CO2 FTIR (possible input from the GEOMON project) Otherwise comparison with surface pressure normalised FTIR data Start of validation: month 20 Extraction of SCIA overpass data for FTIR stations Averaging kernels for SCIA measurements will be provided

4 SCIAMACHY CO Historical dataset from UFTIR available Input for modelling activities

5 IASI To be discussed on the next meeting: –Retrieval algorithm –Comparison strategie with SCIAMACHY and FTIR –Possibility of combined SCIAMACHY/IASI retrieval –Initially focus on retrieval over FTIR stations
