Produits altimétriques global SLA et ADT - Hauteurs - (monomission, L3, le long de la trace)

For the Global Ocean - 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.

Statement

Detailed description:

This product is processed by the SL-TAC multimission altimeter data processing system. It processes data from all altimeter missions: Sentinel-6 Michael Freilich, Jason-3, Sentinel-3A et 3B, HY-2A, Saral/AltiKa, Cryosat-2, Jason-2, Jason-1, T/P, ENVISAT, GFO, ERS1/2. It provides a consistent and homogeneous catalogue of products for varied applications, both for near real time applications and offline studies. Two resolutions are proposed (appears in the file name): *vfec* : for validated, filtered, sub-sampled and LWE-corrected data *vxxc* (named unfiltered) : for validated, NON-filtered, NON-sub-sampled and LWE-corrected data

Horizontal sampling:

14km for filtered, 7km for unfiltered
