3D reconstruction of horizontal and vertical quasi-geostrophic currents in the North Atlantic Ocean
In this paper we introduce a new high-resolution ( 1/10°) data-driven dataset of 3D ocean currents developed by the National Research Council of Italy in the framework of the European Space Agency World Ocean Circulation project: the WOC-NATL3D dataset. The product domain extends over a wide portion...
