The new finite element global tides atlas FES2012, aimed to replace the FES2004 atlas, is now under way!!!

It is funded by the CNES agency (Centre National d'Etudes Spatiales) and supported by CNRS (Conseil National de la Recherche Scientifique). It involves the LEGOS laboratory and two science engineering companies, Noveltis and CLS.

The two primary objectives are to take profit of the long-running altimeter missions records and to increase the atlas spatial resolution. The FES2012 atlas should be available in fall 2012.

This project also aims to be a tribute to the outstanding contribution of C. Le Provost to the Topex/Poseidon tidal modeling achievements.

LEGOS project team: F. Lyard, L. Roblou, D. Allain, L. Testut

Additional contributors: F. Birol and C. Delebecque (CTOH/LEGOS), M.Llubbes (GET), D. Greenberg (BIO), B. Levier (Mercator-Ocean)
