Beginning in 1978 with the first Earth orbiting ocean observing satellite, Seasat, continuing with Geosat, ERS-1,TOPEX/Poseidon, ERS-2, Jason-1, Envisat and Jason-2 missions and looking ahead to the Surface Water and Ocean Topography (SWOT) mission scheduled to launch in 2020, the improvement of the spatial resolution in NASA and partners altimetric missions is dramatic. This animation illustrates this progression of improved data resolution. SWOT will provide sea surface height and hydrography measurements at very high spatial and temporal resolutions unlike anything that has ever been available.
