Abstract

Measuring the Change of Aerosol Composition in the Urban Plume of Hamburg by a Lagrangian Experiment A contribution to subproject AEROSOL Michael Schulz and Ralph Tiede Institut fur Anorganische und Angewandte Chemie, Universitat Hamburg, Martin-Luther-King-Platz 6, D-20146 Hamburg, Germany Introduction A key process which determines the life time of various anthropogenic atmospheric pollutants, emitted in gaseous form, is particle formation in the urban plume. At the same time it is the major reason why the urban plume aerosol composition is expected to change over a short range after leaving the urban area. The important parameters which determine the rate of particle formation can not be identified easily. They depend on the rate of a variety of chemical transformation processes and the primary emissions of particles and gases in the urban congregation, but also on the background composit
