Retrieval of wave parameters with Altimeter; Wind and wave from radar altimetry satellites: measurements and uses.(Vinca Rosmorduc CLS / AVISO)
Radar altimetry satellites have been measuring the Earth’s ocean since 1991. Currently Jason-2, Envisat and Jason-1 are operational. If the main objective of those are the measurement of sea surface height, wind speed (modulus) and significant wave heights are very useful “bonuses” to this techniques. The presentation will explain how these quantities are retrieved from the altimeter measurements, and how they are used in meteorology, climatology and oceanography.
Sea surface height variation & mean sea level applications from radar altimetry (Vinca Rosmorduc CLS / AVISO)
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:
