The Altimetry, Ocean Colour, Sea Surface Temperature and Atmospheric Composition global data are available in different latency modes, as shown in the following table:
| Latency modes | Description | Time archive | Data type |
|---|---|---|---|
| Near Real-Time (NRT) | Products available to users within three hours after sensing | 1 month | Altimetry, Atmospheric Composition, Ocean Colour, Sea Surface Temperature |
| Short time critical (STC) | Products available to users within 48 hours after sensing | 1 month | Altimetry |
| Non time critical (NTC) | Products available to users within one month after sensing | 1 year | Altimetry, Ocean Colour, Sea Surface Temperature |
How to access CODA
If you already have an Earth Observation Portal (EO Portal) account, use your account credentials to log into CODA (please use Chrome or Firefox). Click ‘OK’ to be redirected to the Earth Observation Portal login screen.
Alternatively go to the EO Portal, log in and follow the link 'Access CODA'.
CODA can also be access through it's API, examples of using this in the Python programming language are available on the EUMETSAT gitlab.
If you do not have an EO Portal account, simply create one and follow the link 'Access CODA'.

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 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:
In the following table, some information about the reprocessed datasets available via CODAREP.
| OLCI reprocessed data | SLSTR reprocessed data | SRAL reprocessed data | |
|---|---|---|---|
| Timeliness | Non Time Critical data (NTC) | Non Time Critical data (NTC) | Non Time Critical data (NTC) |
| Latest reprocessed Baseline | 2.23 (S3A L1&L2) 1.30 (S3B L1) |
2.29 (L1 RBT) 2.33 (L2 WST) |
2.61 |
| Dates | S3A: From 26 April 2016 to 29 November 2017. Datasets from 30 November 2017 onwards can be found on CODA and the EUMETSAT Data Centre* S3B: L1 from 15 May 2018 to 29 October 2019. Data sets from 29 October 2019 onwards can be found on CODA. L2 is not yet reprocessed. |
From 19 April 2016 to 04 April 2018 Datasets from 05 April 2018 onwards can be found on CODA and the EUMETSAT Data Centre* |
Reprocessed datasets using PB 2.61 from 1 March 2016 – 31 December 2019 are available on CODArep Datasets from 01 January 2020 onwards can be found on CODA.

| Product Types and Levels | S3A L1 (OL_1_EFR___ and OL_1_ERR___) S3A L2 (OL_2_WFR___ and OL_2_WRR___) S3B L1 (OL_1_EFR___ and OL_1_ERR___) |
L1 (SL_1_RBT___) L2 (SL_2_WST___) |
L1B (SR_1_SRA___) L2 (SR_2_WAT___) L1A and L1B-S to come |
*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.
