Satellite-based Earth observation of river discharge, with its global coverage and consistent accuracy, has emerged as a promising alternative to in situ measurements. The Institute of Geodesy (GIS), within the Faculty of Aerospace Engineering and Geodesy at University of Stuttgart has extensive expertise in hydrogeodesy. In recent years, GIS has initiated and contributed to various studies and projects exploring the application of spaceborne geodetic sensors for hydrological research. Some of these efforts focus on deriving river discharge estimates from satellite altimetry, satellite images and satellite gravimetry.
The results of these studies are now also available as project datasets via the GRDC website. Here you will find an overview of the space-based extensions to global-scale in situ river discharge measurements, developed by GIS using discharge time series from GRDC and other sources.
