This volume is the outcome of contributions from 51 scientists who were invited to expose their latest findings on precipitation research and in particular, on the measurement, estimation and prediction of precipitation. The reader is presented with a blend of theoretical, mathematical and technical treatise of precipitation science but also with authentic applications, ranging from local field experiments and country-scale campaigns to multinational space endeavors. This book is addressed to all scientists involved in precipitation research, but also to those researchers from the wider area of atmospheric sciences whose interests touch on such an extremely important weather phenomenon as precipitation. Moreover, the book aims at introducing newcomers in the field of precipitation science to the various up-to-date scientific facets of the subject, by exposing the full dimensions of the measurement, estimation and prediction of precipitation. The book is prologued by Prof. Eric A. Smith.
