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.
Satellite Altimetry Used to Better Represent Ocean Circulation
WebNov 22, 2024 · By measuring the amount of time it takes the signal to return to the satellite, analysts can calculate the difference in height between the ocean surface and the sea ice surface, or the thickness of the ice sheet. Radar and laser altimetry aren’t substitutes but operate in tandem to create an accurate depiction of sea ice melt. The former can ...
