emission control strategies under a variety of conditions. While such a program should have a clear link to regulatory objectives, it should be structured and funded in su¢~ a way as to be free of short-term political influences. The book is very well written, albeit densely. It is accessible to any scientist. "f~.:~won't find a more objective or more exhaustive treatise on the subject of tropospheric ozone. The authors leave no stone unturned, and offer feasible and constructive recommendations for how to tackle this difficult problem m the future. Although the book may be somewhat peripheral to aerosol science per se, the general subject area covered is closely related to the work of the many aerosol scientists involved in the highly-multidisciplinary field of air pollution research.

Microelimate and Spray Dispersion. DAVID H. BACHE and DONALDR. OHNSTONE. Ellis Horwood, Chichester, U.K. (1992). ISBN 0-13-217910-5. 238 pages. This book deals with the meteorology of the surface layer of the earth's atmosphere and with how this relates to the dispersion of liquid sprays intended for pesticide applications. The main aim is to provide a theoretical framework for describing such spray dispersion over the wide ranges of practical conditions that might be encountered in practice. Early chapters describe the strategic and economic background to the widespread use of pesticide sprays, and the nature of air flows in the atmospheric boundary layer (in particular over complex terrains and within plant canopies). Later chapters go on to describe the physics of the relevant spray generation processes, and of the subsequent dispersion and deposition of droplets. The final chapters deal with practical applications of these physical concepts. and with meteorological and (potential) pollutant monitoring. The book follows a logical sequence, describing a branch of applied aerosol science which is of considerable economic importance by means of an approach which is firmly based on firm physical reasoning. The text is well-written, pitched at a level which is easily manageable by any graduate in one of the physical sciences. The overall presentation is attractive, with clear diagrams and layout. The book is recommended reading for all those with interests in liquid spray generation and technology and in aerosol transport low down in the earth's atmosphere. JAMESH. VINCENT
