Gridded Sea Level Heights and geostrophic currents - Antarctic Ocean
Types of dataset: Experimental Ssalto/Duacs gridded multimission altimeter products dedicated to Antarctic Ocean. This dataset is one of the experimental products which are available on the SSALTO/DUACS experimental products
DOI: 10.24400/527896/a01-2022.010 - more metadata
Contents: multimission sea level heights computed with respect to a twenty-year mean and associated geostrophic current anomalies. The formal error is also included.
Condition of access : Users should keep in mind that these products are experimental products. Notably, they are not produced on an operational basis.
Description: Sea level and geostrophic current anomalies grids for the Antarctic Ocean from radar altimeter measurements, available for 1 multimission file combining 3 satellites : SARAL/AltiKa, Cryosat-2 and Sentinel-3A.
