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.

The CTOH computes and distributes specific, coastal along-track sea level anomalies (SLA) using its X-TRACK processor over 23 regions, for all precise altimeter missions : Topex/Jason-1/Jason-2/Jason-3 (+Topex Interleaved orbit (TPN)/Jason-1 Interleaved orbit (J1N)), SARAL/AltiKa, Envisat, Geosat Follow On The CTOH computes and distributes specific, coastal along-track sea level anomalies (SLA) using its X-TRACK processor for all precise altimeter missions : Topex/Poseidon (TP), Jason-1 (J1) , Jason-1 interleaved (J1N), Topex/Poseidon interleaved (TPN), Jason-2, Geosat Follow on (GFO) and Envisat. X-TRACK cover today all the coastal oceans, with 23 new regions.

Multimission altimetry-derived gridded from Ssalto/Duacs products backward-in-time Finite Size Lyapunov Exponents and Orientations of associated eigenvectors

Monomission Sentinel-3A altimetry product, LR-RMC mode (Low-Resolution with Range Migration Correction) with along-track level-2 estimations at 20Hz rate in LR-RMC mode. LR-RMC associated waveforms are also included, as well with the geophysical corrections applied to the altimeter range (SGDR files).

Ssalto/Duacs multimission gridded sea surface heights products. From January 1993 to the last extension of the Delayed-time products, the long delayed-time dataset allows to compute statistical means of Maps of Sea Level Anomalies (MSLA) over different periods of time. Computed with respect to a twenty-year mean profile [1993-2012], and including the seasonal variability (no annual cycle is removed).

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).

Significant Wave Height (SWH) monomission along-track altimeter satellite product available for Sentinel-3A, Sentinel-3B and Sentinel-6 Michael Freilich missions in Near-Real-Time. SWH values are computed from the High Resolution Mode, also known as Synthetic Aperture Radar mode (SAR) and are calibrated relative to buoys. A validity flag and the applied correction are also provided. Since April 2021, a new variable is included in the files : wind speed, computed by Gourrion (2002) algorithm using Collard (2005) table with PLRM sigma0 and SWH. Moreover, the values are cross-calibrated with Jason-3 standard F wind speed.
