            <gco:CharacterString>La surface moyenne océanique (Mean Sea Surface MSS, en anglais) est un élément important en océanographie physique, en géophysique et en géodésie. 
Elle correspond à la hauteur moyenne stable, de la surface de l'océan..
Le produit MSS CNES CLS est un produit altimétrique auxiliaire représentant la hauteur moyenne de l'océan par rapport à l'ellipsoïde de référence T/P ou WGS84. Cette surface est fournie sur une grille régulière (1/60°x1/60°). Une grille d'erreur d'estimation est également fournie.</gco:CharacterString>

                  <gco:CharacterString>Utilisation: géodésie, géophysique, océanographie (opérationnelle, modélisation, étude de la variabilité océanique), validation de la mesure altimétrique
Description: produit altimétrique combiné sur période de référence de 20 ans (1993-2012), basé sur 29 années de mesures altimétriques (profils moyens, phase géodésiques et anomalies de hauteurs de mer) des missions comme Topex/Poséidon, Jason-1&amp;2&amp;3, GFO, ERS-2 Envisat, Cryosat-2, SARAL/AltiKa, Sentinel-3A&amp;B. La combinaison des missions nécessite de recaler les missions entre elles. Pour cela une mission de référence est choisie et les autres sont calées sur elle.
Couverture géographique: globale  (79.4°S - 88°N)
