Produit dérivé de niveau 2P estimés à partir de l’instrument SWIM de CFOSAT

Dérive de Stokes calculée à partir des spectres de CFOSAT/SWIM et avec plusieurs modélisations. La dérive de Stokes est le vecteur d'écoulement moyen lagrangien sous l'action des seules vagues de surface. Elle est principalement significative à la surface de l'océan, mais peut l'être jusqu'à quelques dizaines de mètres sous la surface. Le produit contient également des variables relatives à la nadir box (SWH du nadir, vitesse du vent du nadir, angle) et des variables off-nadir (telles que le spectre de pente moyen pour un faisceau spectral de 10 degrés).
