DUACS Products

General Overview

The DUACS system delivers satellite altimeter sea level products for different Copernicus services:

  • The Copernicus Marine Service  provides regular and systematic reference information for the global ocean and the European regional seas. Satellites products are delivered in near-real time and also delayed-time and they focus on the best estimate and sampling of the ocean at each moment.
  • The Copernicus Climate Change Service (C3S) responds to environmental and societal challenges associated with human-induced climate changes. The service will provide access to several climate indicators (e.g. sea level rise) and climate indices for both the identified climate drivers and the expected climate impacts. This service delivers DUACS delayed-time sea level products focused on the homogeneity and stability of the record.

The system is also used for the production of demonstration and pre-operational products for CNES/AVISO.

The different Altimeter sea level products generated by the DUACS system and the link to the respective catalogue webpages are presented in the following page (Summary), according to their thematic and the different services in charge of their distribution):
