Book Description
Satellite nadir altimetry uses a space-based sensor to repeatedly measure the height, allowing geodesists and other Earth scientists to monitor temporal changes in surface height on a global or regional basis. Satellite altimetry was originally designed for observing and monitoring global ocean surface topography, but innovative methodologies have been developed and demonstrated for sensing non-ocean surfaces. In this study, two non-ocean altimetry applications have been explored and examined: lake ice thickness retrieval in the Laurentian Great Lakes, and land subsidence rate derivation at San Joaquin Valley.

Book Description
Satellite remote sensing is the primary tool for measuring global changes in the land, ocean, biosphere, and atmosphere. Over the past three decades, active remote sensing technologies have enabled increasingly precise measurements of Earth processes, allowing new science questions to be asked and answered. As this measurement precision increases, so does the need for a precise geodetic infrastructure. Evolving the Geodetic Infrastructure to Meet New Scientific Needs summarizes progress in maintaining and improving the geodetic infrastructure and identifies improvements to meet new science needs that were laid out in the 2018 report Thriving on Our Changing Planet: A Decadal Strategy for Earth Observation from Space. Focusing on sea-level change, the terrestrial water cycle, geological hazards, weather and climate, and ecosystems, this study examines the specific aspects of the geodetic infrastructure that need to be maintained or improved to help answer the science questions being considered.

Book Description
Rising sea levels, originated from global climate change, lead to increasing number of inhabitants exposed to catastrophe damages. Hence, monitoring and observing sea level and its variation are of great significance, especially for the population living in the coastal regions. Recently, the ground-based Global Navigation Satellite System Reflectometry (GNSS-R) technique has been developed and applied to measure coastal sea level and lake level, to complement contemporary methods such as tide gauges and satellite radar altimetry. Compared with conventional techniques of tide gauge, this GNSS-R altimetry is capable of measuring absolute or geocentric sea level, or lake level height without land vertical motion contaminations. Additionally, it behaves much better in the coastal regions than traditional pulse-limited radar altimetry. As a result, the GNSS-R altimetry technique can potentially mitigate the temporal and spatial deficiency of historical and current sea level records.

Book Description
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 )
