Products Gridded and along-track Sea Level Heights - Arctic Ocean
Types of dataset: Experimental Ssalto/Duacs gridded and along-track monomission and multimission altimeter products dedicated to Arctic Ocean. This dataset is one of the experimental products which are available on the SSALTO/DUACS experimental products
DOI: 10.24400/527896/a01-2020.001 - more metadata
Contents: multimission sea level heights computed with respect to a twenty-year mean.
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 anomaly for the Arctic Ocean from radar altimeter measurements, available for 3 monomission files (along-track and gridded): SARAL/AltiKa, Cryosat-2 and Copernicus Sentinel-3A and also for a multimission gridded file combining the 3 satellites.
Citation: When using the SSALTO/DUACS experimental products, please cite: "Those products were processed by SSALTO/DUACS (DOI 10.24400/527896/a01-2020.001 version 2.X) and distributed by AVISO+ (https://www.aviso.altimetry.fr) with support from CNES”
Geographic coverage: Arctic Ocean.
