WebJul 7, 2024 · The surface of the ocean bulges outward and inward, mimicking the topography of the ocean floor. The bumps, too small to be seen, can be measured by a radar altimeter aboard a satellite. … These bumps and dips can be mapped using a very accurate radar altimeter mounted on a satellite. WebBecause satellite altimetry degrades significantly as it nears the coast, the station must be offshore to allow for a valid data comparison. The satellite passes over the station once every 10 days. The other tide station used to verify Jason-3 data is located near the Italian island of Corsica, and is operated by European partners.
