Abstract

Since the launch of Topex/Poseidon, more than 13 years ago, satellite altimetry has evolved in parallel with the user community and oceanography. As a result of this evolution, we now have:

- A bigger choice of products, more and more easy-to-use, spanning complete GDRs to pre-computed sea level anomalies and gridded datasets

- a mature approach, combining altimetric data from various satellites and merging data acquired using different observation techniques, including altimetry, to give us a global view of the ocean;

- data available in real or near-real time for operational use.

Aviso have been distributing Topex/Poseidon and ERS altimetric data worldwide since 1992, and Jason-1 and Envisat since 2002. Soon Cryosat data will join the crew… Integration of all those missions is one of the keys to global modeling of the ocean for assimilation in Godae. An overview of available products, describing their applications and features, will be presented.
