Follow live discussions: Sea-level rise and Sentinel-6

Sea levels have not only been rising over the past 25 years, but are accelerating, putting coastal communities and multiple megacities at risk. In November 2020, the Copernicus Sentinel-6 Michael Freilich satellite will be launched to map, measure and monitor exactly this, so we can understand and mitigate its consequences.

With a coastline of more than 100 000 km, many of Europe’s densely populated coastal zones are vulnerable to coastal flooding. Through this series of webinars, we will hear more from ESA experts, journalists, policy-makers and activists as they discuss sea-level rise in Europe.

Learn more about why the Copernicus Sentinel-6 mission is essential for climate data records, why space altimetry is the most powerful tool we have to measure sea-level rise and how we can protect low-lying communities under threat.

Sea level and Sentinel-6

Reliable, accurate and long-term observations of sea level rise and its impact on coastal areas are vital to be able to plan and better protect the ten percent of the world’s population living less than ten metres above sea level.

The Copernicus Sentinel-6 mission comprises two identical satellites launched five years apart. Firstly, Copernicus Sentinel-6 Michael Freilich, scheduled for launch in November 2020, and then Copernicus Sentinel-6B in 2025 to supply measurements until at least 2030.

The satellites reach 66°N and 66°S – a specific orbit occupied by the earlier missions that supplied the reference sea-surface height data over the last three decades. This orbit allows 95% of Earth’s ice-free ocean to be mapped every 10 days.

While Sentinel-6 is one of the European Union’s family of Copernicus satellite missions, its implementation is the result of a unique cooperation between ESA, Eumetsat, NASA and NOAA.
