The aerosol optical thickness retrieval from GOME spectra

A prototype processor for the aerosol optical thickness retrieval and aerosol classification starting from GOME data has been developed. The aerosol classification is made choosing the minimum among the least squares residuals computed for different aerosol classes. For each pixel the output of processor gives the aerosol optical thickness, the aerosol classification, a relative retrieval residual and a flag that indicates if the pixel is cloudy. The results of some different GOME real data sets are shown.
