Products SSALTO/DUACS Experimental products: gridded Sea Level Heights and velocities with Dynamic Interpolation
Types of dataset: Ssalto/Duacs mutlimission altimeter products "Experimental". Preparation to the SWOT Era.
Contents: multimission sea surface heights computed with respect to a twenty-year mean, gridded Sea Level Heights and geostrophic velocities computed with Dynamic Interpolation Ocean Science Topography (DYMOST) (1/8°x1/8° on cartesian grid),
Use: regional studies, ocean variability (mesoscale circulation,...)
Condition of access : Users should keep in mind that these products are experimental products. Notably, they are not produced on an operational basis.
Citation: When using the SSALTO/DUACS experimental products, please cite: "Those products were processed by SSALTO/DUACS and distributed by AVISO+ (https://www.aviso.altimetry.fr) with support from CNES”
Description: regional product resulting from specific processes, available in delayed time.
Geographic coverage: few test zones are provided to users: Gulf Stream, Udinstev
