Overview
Ssalto/Duacs multimission gridded geostrophic velocities anomalies deduced from the Absolute Dynamic Topography with the method of Arbic et al., 2012 outside [-5°;5°] in latitude and of Lagerloef et al., 1999 in the tropical zone.

Use : Ssalto/Duacs gridded products are devoted to scientific applications: study of general circulation (ocean gyres, …), including operational oceanography (near-real time products).
