Improved circulation in Mediterranean Sea

In the new Ssalto/Duacs v3.0.0, the reference surface (or mean profiles) used for SLA computation was improved with respect to the previous version. Improved quality of the mean profiles, combined with higher quality of the altimeter measurement and processing, allowed us to improve the spatial coverage of the data specially in coastal areas or enclosed seas.

As the global ocean product, the regional product over the Mediterranean Sea takes advantage of the DT Duacs reprocessing.

For example, on the date 2006-07-19, the western Alboran eddy (the first one just after the Gibraltar Strait) is better visible with the new Ssalto/Duacs v3.0.0.
