    To access the products via EUMETCast, users should register via our Earth Observation Portal (EOP).

  • EUMETCast Terrestrial
    To access the products via EUMETCast Terrestrial users need to be eligible for access to a National Research and Education Network (NREN) which supports multicasting. Users with access to a suitable NREN can request access to the Sentinel-3 Terrestrial service via the Earth Observation Portal (EOP).
  • The EUMETSAT Data Centre (accessible via our EOP)
  • Our new pilot Copernicus Online Data Access (CODA) service. It is an online rolling archive with http access. If you would like to have access to the pilot CODA service, please email the User Service Helpdesk with subject ‘CODA access’. A CODA account will be created for you and you will receive an email with your CODA account credentials shortly thereafter.

    There is a plan to implement at a later stage a single sign-on with our EOP, so you will then be able to access the CODA with your EOP credentials.

More information on OLCI products and accessing the data can be found on the Sentinel-3 Services Ocean Colour page.

Other products from Sentinel-3 will be made available in the coming weeks.
