This book will bring an integrated view of the state-of-the art in the matter to the water scientists eager to add Radar Altimetry to their toolkit. It describes experience in application of satellite altimetry to the different inland seas, lakes and rivers in the World. It presents the principal problems related to the altimetry derived products in inland seas, lakes and rivers and ways of their improvement. This publication is based on numerous satellite and observational data collected and analyzed by the authors of the various chapters in the framework of a set of international projects, performed in Europe, Russia, USA, and China. The book will contribute both to the ongoing International Altimeter Service effort and to the building of a sustained Continental Water observing system in the perspective of GMES and GEOSS initiatives, supplied with satellite data from the series of Sentinel-3 satellites, the Jason series and further on the revolutionary SWOT Satellite Mission. This book is aimed at specialists concerned with research in the various fields of satellite altimetry and remote sensing of Continental Waters. The book will also be interesting for lecturers, students and post-graduate students. Pratical applications stemming from the book content will be supported by, and can be advertised through, the ESA-CNES Basic Radar Altimetry Toolbox and its Radar Altimetry Tutorial ( http://earth.esa.int/brat, http://www.altimetry.info )
