dc.descriptionNew WFM-DOAS retrieval algorithm products, CO (v0.6) and CH4 (v1.0) have recently become available. The total column amounts of these CO and CH4 products, retrieved from SCIAMACHY nadir observations in its near-infrared channels, have been compared to data from a European harmonized FTIR network as developed during the UFTIR project (http://www.nilu.no/uftir). The years considered are 2003 and 2004 only (the new WFM-DOAS data is also available for the year 2005). Comparisons have been made for individual data, as well as for monthly averages. To maximize the number of reliable coincidences that satisfy the temporal and spatial collocation criteria, the SCIAMACHY data have been compared with a temporal 3rd order polynomial interpolation of the ground-based data. For comparison purposes we have also compared the old v0.5 datasets with the same FTIR measurement ensemble. The validation shows a clear improvement of the data quality with the new version products.
