Type of dataset: Level-3 (nadir along-track) and Level-4 (gridded) altimetry products.

Contents: real along-track nadir altimeter SSH L3 products; Delayed Time merged all satellites SSH L4 products based on several mapping solutions.

DOI: 10.24400/527896/a01-2021.005   -  more metadata

Use: regional studies; ocean variability (mesoscale circulation), data challenge. For example, it will allow investigating the performance of mapping algorithms with recent and future altimeters constellation.

Condition of access: The 2021A_SSH_MAPPING_OSE products are available free of charge for any project or study.

Data access service: OpenDap

Citation: Publications should include the following statement in the Acknowledgments: “The data used in this study (DOI: 10.24400/527896/a01-2021.005) were developed, validated by CLS and MEOM Team from IGE (CNRS-UGA-IRD-G-INP), France and distributed by Aviso+”.

Description: Following the Observation System Experiment (OSE) framework, the SSH observations include SARAL/Altika, Cryosat-2, Haiyang-2A, Jason-2, Jason-3 and Sentinel-3A altimeter data. These along-track data are distributed by the Copernicus Marine Service (CMEMS) [1], here only an extraction of the data over the Gulfstream region is provided. This nadir altimeters constellation was operating during the 2017-01-01 to 2017-12-31 period. Several gridded products constructed with the SARAL/Altika, Jason 1, Haiyang-2A, Jason-2, Jason-3 and Sentinel-3A altimeter data are also provided. The Cryosat-2 dataset is used for independent validation.

Geographic coverage: Gulf Stream [65°W-55°W][33°N-43°N]

Format: NetCDF-4 Classic with CF standards.
