Aviso
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), 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.
