                  <gco:CharacterString>Contenu : anomalies de hauteurs de mer le long de la trace par rapport à l'ellipsoïde de référence, corrigées des effets géophysiques. Les datasets ont une résolution spatiale de 1Hz pour toutes les missions et une résolution de  20Hz pour les missions Copernicus Sentinel-3A&amp;B, Sentinel-6MF, Jason-3 en Short Time Critical (STC) et Near-Real-Time (NRT).
Utilisation : étude de phénomènes océaniques et géophysiques stationnaires ou à variations très lentes. Les corrections utilisées sont fournies, ce qui offre la possibilité à l'utilisateur de les substituer au profit d'autres algorithmes.
Description : Produit altimétrique mono-satellite plus corrections et surfaces géophysiques associées. Les hauteurs de vagues et les coefficients de rétrodiffusion sont aussi livrés dans les fichiers (excepté pour Sentinel-3A). Par définition et à la différence des produits multimission Ssalto/Duacs, les produits monomission ne sont pas intercalibrés aux points de croisement. Il est donc possible que les données Jason-1 et Envisat, par exemple, ne soient pas homogènes, puisque leur orbite est différente. Ces produits ne sont pas corrigés du biais à grande longueur d'onde (Large Wavelength Error -LWE-), à la différence des produits multimission Ssalto/Duacs.
