Beschreibung / Inhaltsverzeichnis:
Satellite remote sensing, in particular by radar altimetry, is a crucial technique for observations of the ocean surface and of many aspects of land surfaces, and of paramount importance for climate and environmental studies. It provides a state-of-the-art overview of the satellite altimetry techniques and related missions.
