Sealevel_GLO_PHY_L4_REP_observations_008_047

This dataset is a satellite global sea level product downloaded from the Copernicus Marine Environment Monitoring Service (CMEMS). For more information and the official documentation, including the product manual refer to the | CMEMS data portal. The following brief description is copied over from the original website. For the Global Ocean - Multimission altimeter satellite gridded sea surface heights and derived variables computed with respect to a twenty-year mean. Previously distributed by Aviso+, no change in the scientific content. All the missions are homogenized with respect to a reference mission which is currently OSTM/Jason-2. The sla is computed with an optimal and centered computation time window (6 weeks before and after the date). Two kinds of datasets are proposed: filtered (nominal dataset) and unfiltered.

Resolution is 0.25X0.25 degrees and has an irregular temporal resolution. The data starts in 1993 and it's ongoing.
