Jason satellite series
The oceanographic altimeter satellites of the Jason series have been collecting high accuracy measurements of the global ocean's topography since early 1990s, providing a continuous data record of the ocean's response to climate change, especially sea [level rise]. They also measure topography of inland waters, which is important for understanding droughts and floods. The Jason series satellites have been developed and operated by a broad collaboration of US and European institutions including NASA, CNES, NOAA, EUMETSAT, and ESA. The latest iteration, two identical Jason-CS/Sentinel-6 satellites, is part of the European Union's Copernicus Programme.
