Retrieval of multimodal aerosol size distribution by inversion of multiwavelength data

The ill-posed problem of aerosol size distribution determination from a small number of backscatter and extinction measurements was solved successfully with a mollifier method which is advantageous since the ill-posed part is performed on exactly given quantities, the points r where n(r) is evaluated may be freely selected. A new two- dimensional model for the troposphere is proposed.
