In our work, we retrieve aerosol optical thickness and single scattering albedo by inverting O2 A and B-Band
spectra measured by the DOAS satellite instrument SCIAMACHY onboard Envisat. We present retrievals over
selected AERONET stations to represent different types of aerosols and ground albedos and compare them with
coincident sunphotometer measurements. We also present first attemps at retrieving information on the complex
refractive index and size distribution of the aerosol using parts of the entire spectrum (0.2-1.5 nm) devoid of
strong molecular absorption. Since SCIAMACHY does not support multiple geometries in the Nadir viewing
mode, the wide spectral coverage and medium spectral resolution of the instrument are vital to our retrieval. An
overview of the inversion procedure and radiative transfer model used for retrieval is also provided.
