Copernicus Sentinel-6 carries a radar altimeter to observe changes in sea-surface topography with centimetre precision, providing insights into global sea levels. These measurements are not only critical for monitoring our rising seas, but also for climate forecasting, sustainable ocean-resource management, coastal management and environmental protection, the fishing industry, and more. The Copernicus Sentinel-6 mission will assume the critical role of monitoring sea-level change by extending the long-term measurement record of global mean sea level from space.
