Along-track Sea Level Heights

Types of dataset: Ssalto/Duacs along-track multimission altimeter products. 
Contents: multimission sea surface heights computed with respect to a twenty-year mean. Several timeliness are proposed: near-real-time and delayed-time. Several variables are proposed: Sea Level Anomaly and Absolute Dynamic Topography filtered and unfiltered in delayed-time.

Condition of access : 

  • The Copernicus Marine Environment Monitoring Service (CMEMS) is in charge of the processing and distribution of the Sea Level Anomaly (SLA-H) and Absolute Dynamic Topography Heights (ADT-H) in near-real-time product and the Sea Level Anomalies and Absolute Dynamic Topography Heights in delayed-time product (formerly distributed by Aviso+, no change in the scientific content). 

Description: 

  • Sea Level Anomaly and Absolute Dynamic Topography Heights in near-real-time product is available during a few months at most, from the latest update of the delayed-time product to today. It is disseminated by CMEMS: see the details in the document Migration AVISO+ to CMEMS and AVISO+ to C3S (section2).
  • Sea Level Anomaly and Absolute Dynamic Topography Heights in delayed-time begins in 1993. It is disseminated by CMEMS: see the details in the document Migration AVISO+ to CMEMS and AVISO+ to C3S (section2).

Geographic coverage: Global.
Copyright: 1993 - ongoing EU Copernicus Marine Service for near-real-time product and delayed-time product.
