Weather radar systems provide data necessary for the understanding of weather systems, improved forecasts (especially critical for severe weather), hydrological applications, flood warnings and also for climate research in which ground verification is needed for global precipitation measurements by satellites. This book offers an accessible overview of advanced methods, applications and modern research from the European perspective. An extensive introductory chapter summarizes the principles of weather radars and discusses the potential of modern radar systems, including Doppler and polarisation techniques, data processing, and error-correction methods. Addressing both specialist researchers and nonspecialists from related areas, this book will also be useful for graduate students wishing to specialize in this field.
