ATMOSPHERIC AEROSOL EXTINCTION IN RELATION TO THE MAJOR COMPONENTS OF FINE PARTICLES IN RURAL AIR IN SUMMER

The atmospheric aerosol particles perturb the radiative balance of the Earth by scattering and absorbing the incoming short-wave radiation. For this reason, the parallel study of the solar radiation extinction (scattering and absorption) with physical and chemical properties of aerosol particles is of particular interest. The preliminary results of such a study carried out in Hungary were presented by Molnar et al. (1999).The aim of the present lecture is to discuss the same problems on the basis of a more extended data set. Briefly, the light scattering were measured in rural air. Simultaneously, the relationship between optical properties and chemical composition of the main compounds (ammonium sulfate and total carbon concentration) of fine aerosols were investigated.
