This dataset provides a level 4 (L4) gap free reconstruction of 2D ocean surface currents obtained through the combination of altimeter-derived geostrophic currents and satellite sea surface temperature (SST) L4 data. This WOC product uses the standard Altimeter-derived geostrophic currents (Copernicus operational product, ¼°) as background information and extracts additional dynamical information from the spatial and temporal gradients of a higher-resolution (HR) satellite-derived SST field (Copernicus OSTIA product, remapped onto a 1/10° grid). In particular, the patterns found in the HR satellite SST enable to compute correction factors that are assigned to the background geostrophic currents provided by the Altimeter system.

The data are available through HTTP and FTP; access to the data is free and open. In order to be informed about changes and to help us keep track of data usage, we encourage users to register at: https://forms.ifremer.fr/lops-siam/access-to-esa-world-ocean-circulation-project-data/

This dataset was generated by CNR (Consiglio Nazionale Ricerche) and is distributed by Ifremer / CERSAT in the frame of the World Ocean Circulation (WOC) project funded by the European Space Agency (ESA).
