Overview

The surface and 15 m ocean current velocities are obtained as the sum of the surface geostrophic current derived from altimetry and wind driven component  applying an empirical  model to ERA5 wind stress. The geostrophic current is computed from the CNES-CLS18 Mean Dynamic Topography added to the altimeter derived geostrophic current anomalies (DUACS18.)
