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

DOI10.24400/527896/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. More information in the AVISO+ Newletter.

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 1.X) and distributed by AVISO+ ( with support from CNES”
