Tracking 30 Years of Sea Level Rise

08.10.2022
On August 10th, 1992, NASA and the French Space Agency, CNES launched TOPEX/Poseidon, the first highly-accurate mission to measure sea level from space. In the 30 years since, TOPEX was followed by Jason-1, Jason-2, Jason-3 and most recently Sentinel-6 Michael Freilich, all of which flew in the same orbit as TOPEX.
