INTRODUCTION The Symposium/Workshop on Solar-Terrestrial Influences on Weather and Climate was held at The Ohio State University on 24-28 July 1978. Its purpose was to provide an international forum for the presentation and discussion of recent research results and ideas regarding the question whether variations in solar outputs affect terrestrial weather and cli mate and, if so, to what extent and through what mechanisms. The Sym posium focused on the results of previous studies and consisted of both invited and contributed papers. The Workshop, on the other hand, built upon these deliberations to develop ideas and directions for future research. Over one hundred persons from eight countries attended the Symposium/ Workshop."

This book contains the lectures presented at the Summer Advanced Study School, 'Magnetospheric Particles and Fields' which was held at Graz, Austria during the period August 4-15, 1975. One hundred and one persons from fifteen different countries attended the Schoo . The authors and publisher have made a special effort for rapid publication of an up-to date status of particles, fields, and processes in planetary magnetospheres. Special thanks are due to the lecturers for their diligent preparation and excellent presentations. The in dividuallectures and the published papers were deliberately limited; the authors' cooper ation in conforming to these specifications is greatly appreciated. Many thanks are due to Drs C. D. Anger, Gerhard Haerendel, George P. Haskell, Carl McIlwain, Vytenis Vasy liunas, Martin Walt, and James Warwick who served as session chairmen during the School and contributed greatly to its success by skillfully directing the discussion period in a stimulating manner after each lecture. Many persons contributed to the success of the School. Drs C. D. Anger, Carl-Gunne Falthammar, Gerhard Haerendel, George P. Haskell, Carl McIlwain, David Nunn, Willi Riedler, Finn Scentsraas, Vytenis M. Vasyliunas, Martin Walt, and James Warwick were especially helpful in preparing the technical program. Dr Willi Riedler assisted in ar ranging for the facilities in Graz. Drs Gerhard Kremser and Martin Friedrich were most helpful with many aspects of the local arrangements in Graz. The assistant editor, Mrs Diana R. McCormac, checked the manuscripts and proofs, and worked hard to achieve a uniform style in this book."

This book contains the lectures presented at the Advanced Study Institute, 'Radiation Trapped in the Earth's Magnetic Field' which was held at the Bergen Tekniske Skole, Bergen, Norway, during the period August 16 through September 3, 1965. Approximately one-third of the time was devoted to discussion. The various Session Chairmen have summarized the essential points brought out in these discussion periods which were generally quite spirited. The authors and the publisher have made a special effort to rapidly publish an up-to-date status concerning the various aspects of trapped radiation. Almost all authors turned in their manuscripts prior to the end of the Institute and all prior to September 30, 1965. It was clearly recognized that rapid publication was essential in this rapidly changing research area. Special thanks are due to the Host, Dr. Odd Dahl, Chr. Michelsen Institute, for making all of the arrangements in Bergen, including excellent living and working facilities. Direct financial support was provided the Institute by: North Atlantic Treaty Organization, Advanced Research Projects Agency, Air Force Cam bridge Research Laboratories, Army Research Office, Defence Atomic Support Agency, and the Office of Naval Research."

Reidel Publishing Company, Dordrecht, Holland Softcover reprint of the hardcover 1 st edition 1971 No part of this book may be reproduced in any form, by print, photoprint, microfilm, or any other means, without written permission from the publisher PREFACE The Editor undertook the preparation of this book for two reasons. The first was to fulfill the need for an introductory level book combining the multidisciplinary aspects of atmospheric pollution. This book does cover most of the key facets: sources and sinks of atmospheric pollutants, atmospheric chemistry, transport and meteorology, effects on human beings and vegetation, and surveillance of air quality. The length of the book was purposely limited so that the cost would be within the means of most interested users. The second reason for preparing this book was stimulated by my mother-in-law, Mrs Clayton D. Root, Councilwoman and member of the Planning Commission of Crown Point, Indiana, who pointed out that all governmental levels must make decisions affecting the atmospheric quality of their regions of responsibility and yet have little information on atmospheric pollution for their assistance. For the most part the achievement of air quality standards is a local problem and every locality is unique.
