Release of Sentinel-3B Ocean and Land Colour Instrument (OLCI) Level-1 products

These data are the first Sentinel-3B OLCI data to be released after the successful completion of the Sentinel-3B commissioning phase.

The Sentinel-3 Product Notice for OLCI Level 1 will be made available shortly. It provides information on the OLCI current processing baseline, product quality, known limitations, and product availability status. It is relevant for both Sentinel-3A and Sentinel-3B OLCI products.

To receive Sentinel-3B UNS (User Notification Service) alerts by email, make sure you update your UNS subscriptions via our Earth Observation Portal (EOP).

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

For any questions, contact the User Service Helpdesk.

The Sentinel-3B OLCI Level-1 data can be accessed via the four means listed below.

1. EUMETCast Satellite (for the data in NRT timeliness)

  • The OLCI L1 Full Resolution NRT data will be distributed on EUMETCast Europe (Second Transponder High Volume Service), channel E2H-S3B-01 (PID: 610, Multicast address: 224.223.224.10).
    Example filename:
    S3B_OL_1_EFR____20181203T112344_20181203T112539_20181203T140137_0115_019_194_1980_MAR_O_NR_002.SEN3.tar
    Frequency: 16 files/orbit (226 files/day)
    Average file size: 600MB
  • The OLCI L1 Reduced Resolution NRT data will be distributed on EUMETCast Europe (Second Transponder High Volume Service), channel E2H-S3B-02 (PID: 610, Multicast address: 224.223.224.13)
    Example filename:
    S3B_OL_1_ERR____20181202T082753_20181202T091206_20181202T105123_2653_019_178______MAR_O_NR_002.SEN3.tar
    Frequency: 1 file/orbit (14 files/day)
    Average file size: 700MB

NOTE: If you are already subscribed to Sentinel-3A OLCI products via EUMETCast Satellite, from 12 December you will receive the corresponding Sentinel-3B OLCI products automatically — no additional registration is required.

2. EUMETCast Terrestrial (for the data in NRT timeliness)

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 EUMETCast Terrestrial service via our Earth Observation Portal (EOP).

The OLCI L1 Full Resolution NRT data will be distributed on channel T01-S3B-01 (Multicast address: 232.223.222.8).

The OLCI L1 Reduced Resolution NRT data will be distributed on channel T01-S3B-02 (Multicast address: 232.223.222.9).

NOTE: If you are already subscribed to Sentinel-3A OLCI products via EUMETCast Terrestrial, from 12 December you will receive the corresponding Sentinel-3B OLCI products automatically — no additional registration is required.

3. Copernicus Online Data Access (CODA) service

CODA is an online rolling archive with http access to Sentinel-3 Level 1 and Level 2 (Marine) global data in different latency modes.

4. EUMETSAT Data Centre

The Data Centre is accessible via our Earth Observation Portal (EOP).
