Inversion of tropospheric profiles of aerosol extinction and HCHO and NO2 mixing ratios from MAX-DOAS observations in Milano during the summer of 2003 and comparison with independent data sets.

The article presents a study which investigates the potential of application of a profile inversion scheme for the retrieval of aerosol extinction and trace gas concentrations on Multiple Axis Differential Optical Absorption Spectroscopy (MAX-DOAS) method. The scheme was applied during the FORMAT-II campaign in Bresso in Milano, Italy on September 4-26, 2003. Two profile parameters are retrieved from the study, the integrated quantities and parameters describing a profiles' height and shape.
