Sentinel-6B continues the most precise sea level measurement record in history into the 2030s. The combined Sentinel-6A and 6B data will determine whether ocean rise is accelerating decade over decade — the key measurement for infrastructure planning in Miami, Shanghai, Amsterdam, Mumbai, and every other coastal city planning its future against a moving sea.
