Copernicus Online Data Access

The Sentinel-3 Products are available through the Copernicus Online Data Access (CODA) service.

CODA is an online rolling archive with https access to Sentinel-3 Level 1 and Level 2 (Altimetry, Ocean Colour, Sea Surface Temperature and Atmospheric Composition) global data in different latency modes, as shown in the following table:

Latency modes Description Time archive
Near Real-Time (NRT) Products available to users within three hours after sensing 1 month
Short time critical (STC) Products available to users within within 48 hours after sensing.
(Only for SRAL products)
 
Non time critical (NTC) Products available to users within one month after sensing 1 year

 

 

How to Access CODA

If you already have an Earth Observation Portal (EO Portal) account, use your account credentials to log into CODA. Go to https://coda.eumetsat.int (please use Chrome or Firefox). Click ‘OK’ to be redirected to the EO Portal login screen.

Alternatively go to https://eoportal.eumetsat.int/userMgmt/login.faces, log in and follow the link 'Access CODA'.

If you do not have an EO Portal account, simply create one and follow the link 'Access CODA'.

For more information read the Sentinel 3 Marine Copernicus Data Access User Manual.

Reprocessed data and obtaining a current and consistent mission dataset

Sentinel-3 data that is older than a year, and datasets from the individual sensors that have been reprocessed, is available from CODAREP, the data centre, and in some cases, via FTP. Access to these sources is available through your Earth Observation Portal (EOP) account credentials, or via direct support from the User Service Helpdesk(in the case of FTP).

Guidance on obtaining the most recently reprocessed data for a specific time period, or a current and consistent dataset for the entire mission, is available at the following links for each sensor:

OLCI
SLSTR
SRAL

In the following table, some information about the reprocessed datasets available via CODAREP.

*Note: data produced with the current operational baseline is available on CODA for one year, after this time it is available at the EUMETSAT data centre.

How to visualise Sentinel-3 data

To open and display data use the Sentinel Application Platform (SNAP),

Information on SNAP can be found in the Sentinel-3 toolbox and SNAP online tutorials.
