From June 4 to August 17, Angelica Tarpanelli, researcher at the Research Institute for Geo-Hydrological Protection of Perugia, is invited by the Jet Propulsion Laboratory (JPL), NASA, in Pasadena, California (USA) to perform research on the estimation of river discharge through satellite remote sensing. The ongoing collaboration involves the development of algorithms for the use of the sensor on board the new Surface Water Ocean Topography (SWOT) satellite mission, specifically designed for monitoring inland waters, which will be launched in 2021.
