This graphic, released on Dec. 10, 2020, shows the first sea level measurements taken by Sentinel-6 Michael Freilich (S6MF), which launched Nov. 21, 2020. It focuses on the ocean off the southern tip of Africa, where red colors indicate higher sea level relative to blue areas, which are lower. Also included are sea surface height measurements from three other satellites for comparison: Jason-3 (JA3), Sentinel-3A (S3A), and Sentinel-3B (S3B).
