Monomission altimeter satellite along-track sea surface heights 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.

This product integrates sea level observations aggregated and validated from the Regional EuroGOOS consortium (Arctic-ROOS, BOOS, NOOS, IBI-ROOS, MONGOOS) and Black Sea GOOS as well as from the Global telecommunication system (GTS) used by the Met Offices. The latest version of Copernicus delayed-mode Sea level product is also distributed from Copernicus Marine catalogue.

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. The acquisition of various altimeter data is a few days at most. The sla is computed with a non-centered computation time window (6 weeks before the date).

Product of simulated SWOT sea surface heights from its 2 altimeters: KaRIn interferometric altimeter and Nadir altimeter. This product includes the Level-2 Low Rate (LR) data (L2_LR_SSH) designed for ocean surfaces and Level-2 and Level-3 SSH corrected by estimations of simulated errors.

Multivariate Inversion of Ocean Surface Topography- Internal Tide (MIOST-IT) Model products. MIOST-IT database includes 4 tidal components for the ocean internal tide surface elevations. Each tidal component is described by 2 grids (amplitude and phase) provided on a cartesian grid 1/10°x1/10°. - The internal tide elevations for the four tidal frequencies M2, S2, K1, O1, are available for download. - The tidal prediction code is also available to download.

Monomission altimeter product: OSTM/Jason-2. These products were produced by CLS in the framework of the Pistach project, funded by Cnes.

Auxiliary products - Tide elevations, Tide currents, Tide loading

The global mean level of the oceans is one of the most important indicators of climate change. It incorporates the reactions from several different components of the climate system. Precise monitoring of changes in the mean level of the oceans, particularly through the use of altimetry satellites, is vitally important, for understanding not just the climate but also the socioeconomic consequences of any rise in sea level.
