Abstract

The aim of our research was to study the influence of a changing air pollution situation in the Polish Sudety mountains on the cloud chemistry. Hill cap clouds occur in this area (above 1300 m. asl), on average 240 days/year. The chemical composition of cloud water samples was dominated by NCV, SO/, NH/ and H*. A wide range concentration levels was observed with maxima of 2631, 1194 and 2268 peq/1 for NCV, SO/ and NH/ , respectively. Concentration changes within an event were particularly evident during periods of changing air mass identity caused by frontal passage. We found that the liquid water content of clouds (LWC) predominantly determines the total solute mass in clouds. The relationship between the total ionic content (TIC-sum of the main inorgan
