The VDI Commission on Air Pollution Prevention - in cooperation with the German Meteorological Society - presents in this book the proceedings of the first International Symposium on Environmental Meteorology , held in Wurzburg (West Germany) from 29 September to 1 October 1987. The primary goal was to get together scientists, experts of the meteorological services, specialists of environmental boards, and consulting engineers of the European countries. An equally important objective was to provide a bench mark document in the resulting proceedings publication. The 1987 symposium shall start a series of symposia on all fields of environmental meteorology to be held once in three or four years in one of the European countries. We are full of hope to come to an intense cooperation with the national meteorological and environmental societies in the countries with this concern. We like to express our sincere appreciation to the authors for their efforts and attention to the quality shown herein. The credit must be extended to the session Chairmen and to the advisory committee for the selection of the papers. We think the book contributes substantially to a better understanding of meteorology being the link between emission and deposition of atmospheric pollutants.
