The first application of the Sentinel-3 topography mission is the study of ocean topography including mean sea level, wave height, wind speed over the surface, sea-ice, ocean currents, Kelvin and Rossby waves, eddies and tides.

The Sentinel-3 along track SAR capability improves measurement quality in coastal zones and over sea-ice due to its higher spatial resolution (SAR).

Other application is the study of land topography including land-ice, land and inland waters.

Examples of these applications and further descriptions can be found in the blue portlet on the right.
