Intercomparison between aerosol characteristics retrieved simultaneously with a Cimel and Prede sun-sky radiometers in Rome, Torvergata Aeronet site

Results from an intercalibration campaign, held at Torvergata, Rome in April 2001, are presented in this work with the aim of defining the range over which aerosol optical and physical characteristics provided by a Cimel and a Prede sunsky radiometers can be compared. The intercomparison procedure between results has been divided into two parts: (i) comparison of aerosol products directly derived from the field measurements in terms of aerosol optical depth and Ångström coefficient, and (ii) comparison of the quantities retrieved from data by using the inversion models, i.e. the volume distribution, the complex refractive index and the single scattering albedo.
