Book Description
An automated model algorithm for identifying hailstorms by radar is described. Hailstorms are identified by totaling seven weighted indicators based on a three-dimensional reflectivity structure of an ideal hailstorm. The weighting functions for each indicator and the total identifying the storms were determined by testing the algorithm with radar data that were verified by ground truth data. By use of these findings, the probability of detecting hail is 94 percent with a false alarm ratio of 6 percent for a critical success index (CSI) = 0.886 for this test sample.

Book Description
Over the past twenty years, there has been a rapid expansion in the number of opera tional, digital weather radars in Europe. Work within COST 73 stimulated the use of data from these radars and also demonstrated the potential of the international exchange of weather radar data in near real-time. The Management Committee of the COST 73 Project have laid the foun dations upon which future international operational radar networking may be built in Europe, and has indicated the directions that future weather radar technological developments might take. Throughout this five year Project, it has been possible to achieve success o~ through the goodwill of the participants. The considerable international co-operation is, in no smaIl measure, the underpinning reason why the Management Committee of COST 73 have been able to address such a wide range of topics within the general category of international weather radar networking. It has been an honour to have had the opportunity to act as Chairman of a group of meteorolo gists, engineers and managers possessing such a wide variety of talents and experience. I would like to take this opportunity to thank them all for their many and varied contributions.

Book Description
This book consists of a diverse collection of chapters that seeks to broaden our fundamental understanding of the ecological function and biological importance of the Earth’s lower atmosphere, which provides a huge living space for billions of animals moving within and across continents. Their migration, dispersal and foraging activities connect water and land habitats within and across continents. Drawing upon the wide-ranging experience of the authors, the book takes an inherently interdisciplinary approach that serves to introduce the reader to the topic of aeroecology, frame some of the basic biological questions that can be addressed within the context of aeroecology, and highlight several existing and emerging technologies that are being used to promote aeroecological studies. The book begins with several background chapters, that provide introduction into such topics as atmospheric science, the concept of the habitat, animal physiology, and methods of navigation. It then continues with a broad discussion of observational methods available to and used by aeroecologists. Finally, several targeted examples of aeroecological studies are presented. Following the development of the chapters, the reader is provided with a unifying framework for investigating how the dynamic properties of meteorological conditions at local, regional, and global scales affect the organisms that depend on the air for foraging and movement. Material presented in the book should be of interest to anyone wishing to gain a comprehensive understanding of the aerosphere itself and the myriad airborne organisms that inhabit and depend upon this environment for their existence. The material should be accessible to a diverse set of readers at all stages of training and across a range of research expertise.
