Sentinel-3 - Monitoring the world's oceans


Sentinel-3B will be launch on 25 April at 17:57 GMT (19:57 CEST) from Plesetsk cosmodrome in Northern Russia.

What will Sentinel-3 do?

The Sentinel-3B satellite carries a suite of instruments to monitor different aspects of the oceans such as the temperature and colour of surface waters, sea surface height and sea ice thickness. It will also monitor land temperature and colour, and aerosols.

The Sentinel-3 mission is based on a constellation of two identical satellites operating in a sun-synchronous, polar orbit at an average altitude of 815 km. Sentinel-3A was launched on 16 February 2016.

The addition of Sentinel-3B will provide higher revisit times (from 3-4 to 1-2 days) and so improved global coverage and timeliness of data.

 

Operating Sentinel-3B and delivering its marine mission

After the launch and early orbit phase and commissioning is completed by ESA, EUMETSAT will operate Sentinel-3B, on behalf of the EU for the Copernicus Programme, delivering marine data and support services to users in the EU, EUMETSAT Member States, and beyond. ESA will deliver the land data.

In addition to Sentinel-3, EUMETSAT is already delivering marine data and support services to users from the Jason-3 ocean altimetry satellite and also from its own and third party missions, and in the future will deliver data from the Jason-CS/Sentinel-6 satellites.

This multi-mission marine data stream is available via EUMETCast satellite/terrestrial, or online via the Copernicus Online Data Access (CODA), the future DIAS system, or through the EUMETSAT Data Centre. Access the full range of ocean products here.

 

How is data from Sentinel-3B used?

Sentinel-3 marine data is used for ocean monitoring and forecasting, weather forecasting (land and marine), management of marine ecosystems, monitoring of water quality and pollution, sea ice charting services and ship routing, and climate monitoring.

On land, the satellites will map land use, monitor vegetation state, measure the height of rivers and lakes, and monitor wildfires.

All instruments onboard the Sentinel-3 satellites are contributing to climate monitoring and extending long-term climate datasets for Essential Climate Variables such as e.g. sea and land surface temperatures, sea level, ocean colour.
