  1. Jason-2 takes to the air

    Date de publication:

    7 Mai 2008

    Since 1992, altimetry satellites have significantly enhanced our knowledge of the world’s oceans. The Jason-2 satellite is all set to take over the ocean-observing mission of its predecessors Jason-1 and Topex/Poseidon. It recently arrived at Vandenberg Air Force Base, California, in preparation for launch on 15 June.

  3. Jason-1 clocks up 10 years of climate observations

    Date de publication:

    7 Décembre 2011

    The Jason-1 ocean-observing satellite has been in orbit for 10 years. In that time, it has helped to build up a 20-year time series of continuous sea-surface measurements to enhance our understanding of climate change.
