As the next radar altimetry reference mission, Copernicus Sentinel-6 is continuing the long-term record of sea-surface height measurements that were started in 1992 by the French–US Topex Poseidon satellite and then by the Jason series of satellite missions.

With millions of people around the world living in coastal regions, sea-level rise is one of the biggest environmental threats we face resulting from climate change.

As our atmosphere and oceans continue to warm, sea levels are likely to continue to rise for many decades, if not centuries.

The Copernicus Sentinel-6 mission comprises two identical satellites launched five years apart to extend the gold standard record of sea-surface height measurements until at least 2030. It also provides near-real time measurements of sea-surface height, significant-wave height and wind speed to support operational oceanography. Over land surfaces, Sentinel-6 provides information on the height of rivers and lakes in support of hydrology applications.

Only space provides the perspective to understand, monitor and act on our changing world.
