Welcome to the Sentinel-3 knowledge base

Welcome to the Sentinel-3 knowledge base

This space is the main entry point for the user guide to data from the Copernicus Sentinel-3 mission. The content contained here and within linked spaces, summarises the key information that end users, both general and specialist, require on the specifics of the Sentinel-3 instruments, the details of the processing system, and the derived marine and atmosphere products. This space includes information on the components of the Sentinel-3 instrument systems, the specifics of measurement techniques used, details on applied corrections, and processing steps required to derive geophysical variables. Further information on product quality and evolutions, file formats, processing tools and data-access routes are presented in complementary spaces linked throughout. Broader information about the science of the instrument measurements and the place of Sentinel-3 in the wider observing system(s) can be found in the altimetry, ocean colour, SST, and atmospheric composition (coming soon) spaces.

You can navigate this around these pages through the sidebar (left hand side) or site overview section (bottom right), via the search box (below), or by following the linked labels in the browse this space by topic section. Information concerning updates to the EUMETSAT satellite services will be shown in the recent satellite services news section at the bottom of the page.

What is the Sentinel-3 mission?

The Sentinel-3 mission is part of the European Commission Copernicus Programme. Each satellite in the mission carries instruments for the observation of the ocean, atmosphere, and land. The satellites are operated by EUMETSAT, who are also responsible for the production of level-1 (L1) and level-2 (L2) marine and atmosphere products. The European Space Agency is responsible for land products derived from Sentinel-3.

Sentinel-3A and 3B were launched in February 2016 and April 2018, respectively. In the longer term, the Sentinel-3 mission will have further satellites (Sentinel-3C and Sentinel-3D), to extend this global monitoring.
