Copernicus Sentinel-3 improves observation of inland waters
28 September 2018
While world-class scientists are meeting in the Azores to discuss how satellites have revealed changes in the height of the sea, ice, inland bodies of water and more, the Copernicus Sentinel-3 satellite has new reasons to shine.
Radar altimeters record the surface topography along the satellite's ground track. They precisely measure the height of water, land and ice by timing the interval between the transmission and reception of very short radar pulses.
