Abstract

The role of clouds in transformation and removal of air pollutants D. Moller, G. Mauersberger Department for Air Chemistry, Fraunhofer Institut for Atmospheric Environmental Research, D-1199 Berlin, Germany ABSTRACT The emission-deposition relationship is discussed from the point of view of multiphase chemistry. The role of clouds is briefly summarized. First results from cloud chemistry measurements at Mt. Brocken (Harz) and modelling are given and discussed in connection with the changing emission situation in the Neue Bundeslander. INTRODUCTION The principal role of clouds in air chemistry consists in a medium (a) for transportation, esp. in linkage between the hydrological and biogeochemical cycles and (b) for transformation, esp. liquid phase chemistry. The role of atmospheric liquid phase chemistry has been referred long time ago [1] as well as the assessment of liquid versus gaseous chemistry [2]. However, a complex v
