Altimetry services

Users need to be registered to get access to the altimetry products. To do this you need to use our Earth Observation Portal (EOP). To access the Earth Observation Portal (EOP) for the first time, users need to create an account. Once the account has been created, you can log in to view and modify your profile, service subscriptions and licence arrangements.

Altimetry products are available via:

• our broadcast delivery system EUMETCast;
• by ordering from the EUMETSAT Data Centre;
• Copernicus Online Data Access (CODA), an online rolling archive with http access.
• Copernicus Online Data Access REProcessed (CODAREP), an online archive of data that has been reprocessed with http access.
• the Copernicus Data and Information Access Service (DIAS), WEkEO.

All Sentinel data products are distributed using a Sentinel-specific variation of the Standard Archive Format for Europe (SAFE) format specification. The information is contained in a single package, with objects encoded in NetCDF format.

Full details can be found on the Sentinel-3 Data Formats page.

The Broadview Radar Altimetry Toolbox is a tool designed to use radar altimetry data, including Sentinel-3.

The Sentinel-3 Altimetry User Guide on the ESA website provides a high level description of the available instrument modes and products.

You can find examples of Python code for working with Sentinel-3 data on the EUMETSAT gitlab.

Detailed guidance on using Sentinel-3 altimetry data can be found in the Sentinel-3 SRAL Marine User Handbook.
