For more than three decades, satellites have been observing the ocean from several hundred kilometers above the surface of the Earth. From the vantage of space, they have given us a global view of the ocean surface and its variability Satellite instruments that are in orbit today detect a broad range of ocean variables that touch on all aspects of oceanography These include sea surface temperature, surface wind velocity, chlorophyll, sea surface elevation, and ice cover, among others. The unifying element of satellite remote sensing is not just that measurements are made from space, but more specifically that satellite instruments detect electromagnetic radiation that is either emitted from or reflected off the surface of the ocean.
