Résumé / Abstract

This paper presents precipitation chemistry data from a continuous record since 1983 at Seehausen, Germany (Neue Bundesländer or former GDR) showing the influence of changing emissions, caused by industrial collapse after German unification, on the chemical composition of the atmosphere. This activity is a part of a joint research project, called by SANA. Another SANA activity, started in 1992 is the monitoring of air pollutants and sampling of cloud water at Mt. Brocken station. The recorded changes in the chemical composition of rainwater, especially when using sectoral data based on backward trajectory calculations, clearly show the source-receptor relationship. The most important result is the decrease of atmospheric neutralizing capacity. By the results of the first continuous cloud chemistry monitoring station in Europe, Mt. Brocken, we also found a strong increase in cloud water acidity. This monitoring program in the background of highly decreasing emissions is a unique opportunity to study atmospheric chemical processes. As an example the continental sea-salt contribution hypothesis is also supported by the result of stations.
