Since the foundation of the SCIAMACHY Quality Working Group (SQWG) in a joint inter-agency effort in late 2006 the ESA operational Level 2 processor was significantly improved w.r.t. data quality and product range. During the last two years the product list was substantially enhanced by new (total columns of SO2, BrO, OClO, H2O, CO; profiles of BrO, Limb Cloud Flag) and improved products (total columns of O3, NO2, Absorbing Aerosol Index; Limb O3 profiles, Limb NO2 profiles). For example, important improvements were achieved in the O3 and NO2 profile retrieval by implementing an upgraded retrieval scheme and using now Level 1 data with an appropriate pointing information. Nadir products of total column O3 and Absorbing Aerosol Index were improved by applying a radiometric degradation correction in the Level 1 to 2 processing step. The paper will summarise on the new Level 2 version 5 ESA products to be released in mid-2009 and the expected data quality. An outlook on the next product version currently under preparation within the SQWG will also be presented.
