Abstract

The performance of electro-optical systems can be substantially affected by aerosol particles that scatter and absorb electromagnetic radiation. A few years ago, an empirical model was developed describing the aerosol size distributions in the Mediterranean coastal atmosphere near Toulon (France). This model has been coupled with Mie theory to yield the code MEDEX (MEDiterranean Extinction) for the aerosol extinction. This contribution deals with the evaluation of MEDEX for aerosol data recorded near the Black Sea coast. For this site, MEDEX correctly predicts the aerosol extinction as function of wavelength, albeit with minor discrepancies below one micron. These differences are attributed to the uncertainty in predicting the concentrations of submicron particles. The comparison shows that MEDEX may be more generally applicable than to the Toulon area.
