Beyond SCIAMACHY's capability to perform global nadir and limb measurements of the Earth's atmosphere in the ultraviolett, visible and near-infrared spectral range, solar occultation measurement are performed during sunrise at higher northern latitudes. Using an optimal estimation approach with the radiative transfer code SCIATRAN as forward model, these measurements are used to derive ozone and NO2 profiles. Here we present an almost complete dataset for the time period 2003 to 2005, including validation results with independent measurements from other satellite instruments and ozone sondes. Additionally, some first case studies for the retrieval of minor trace gases such as OClO are reported.
