Sea Level Measurement from Space Using Sentinel-6 Technology
Discover how sea level is measured from space through advanced technologies such as radar altimeters, microwave radiometers, and satellite dimensions of the Sentinel-6 mission managed by Airbus and ESA. Learn about the key components and processes involved in monitoring sea surface height, geoid gravimetry, and dynamics of tides, waves, and currents. Explore the satellite's dimensions, power sources, launch details, and orbit specifications, emphasizing the critical role of space technology in understanding and addressing sea level rise.
