Experimental altimetry products ocean MIOST Multiscale Interpolation (- Sea Surface Heights and Currents - delayed-time - (multimissions - level 4)

The MIOST (Multiscale Interpolation Ocean Science Topography) experimental altimeter product provides grids at delayed-time, at global scale, 1/10° spatial resolution, the sea surface height (MSLA and MADT) as well as the geostrophic currents, resulting from specific processing. Use for regional studies, ocean variability (mesoscale circulation,...).

Statement

The input data used to compute the gridded products obtained with Multiscale Interpolation Ocean Science Topography (MIOST) are the along-track (or Level-3) SEA LEVEL products delivered by the Copernicus Marine Service (CMEMS, http://marine.copernicus.eu/ ) for satellites OSTM/Jason-2, Jason-3, SARAL/AltiKa, Cryosat-2, HaiYang-2A, Copernicus Sentinel-3A&B.

The Multiscale Interpolation (MIOST) merges along-track ocean altimetry data into continuous maps in time and space. Like the DUACS mapping system, it is based on a linear optimal interpolation scheme, with a different level of covariance function definitions. For this experimental product, we have only considered covariance functions representative of the mesoscale geostrophic variability.
