Attendees from many countries were present; 4 review lectures and about 25 research papers were presented. The realization of the symposium was made possible by the support of Delft University of Technology Koninklijke/Shell-Laboratory Amsterdam Prins Maurits Laboratory/Institute for Chemical and Technological Research Royal Netherlands Meteorological Institute. The symposium organization was carried out by the local organi zing committee consisting of F.G.J. Absil - Delft University of Technology G.W. Colenbrander - Koninklijke/Shell-Laboratory Amsterdam G. Ooms - Delft University of Technology G. Opschoor - Prins Maurits Laboratory/Institute for Chemical and Technological Research H. Tennekes - Royal Netherlands Meteorological Institute A.P. van Ulden - Royal Netherlands Meteorological Institute. The work of the organizing committee was supported in many re spects by the sientific committee, which consisted of H. Fiedler - Technische Hochschule Karlsruhe, Fed. Rep. of Germany F.N. Frenkiel - Naval Ship Research and Development Center, Bethesda, Maryland, U.S.A.J.C.R. Hunt - University of Cambridge, England J. Kondo - National Institute for Environmetal Studies, Japan J.L. Lumley - Cornell University, Ithaca, New York, U.S.A
