Description
Sea surface height variation and mean sea level applications from radar altimetry.
Content
Radar altimetry satellites have been measuring the whole Earth’s ocean since 1991. Currently Jason-2, Envisat and Jason-1 are operational. Their main objective is the measurement of sea surface height variations. With a twenty-years long time series, the possibilities for climate studies are wide. We will describe roughly the data processing and uses, but mostly insist on two different applications:
