Ocean observations from satellite altimeters began with TOPEX/Poseidon in 1992 and continued with Jason-1, 2 & now 3, jointly managed by NASA, CNES, NOAA and EUMETSAT. These satellites have provided detailed observations of sea level rise, ocean circulation and climate change. Not only have they provided sea level heights, but also information on sea ice, hydrology and weather forecasting. [Credit: CNES (Centre National d'Etudes Spatiales) and Mira Productions].
