  2. Jason-2: watching sea level and weather

    Publishing date:

    April 30, 2004

    Satellites monitor sea level, wave height, wind speed and current movements from space. Like its predecessors, Jason-2 will obtain all these data from altimeter range measurements.

  3. Jason-2 delivers its first global maps

    Publishing date:

    March 11, 2010

    The european-US Jason-3 oceanography satellite is scheduled to launch in 2013 to replace Jason-1. Its objective is to continue monitoring sea-surface height and pursue the 21-year time series of high-accuracy ocean altimetry measurements.

  4. A leap forward for oceanography

    Publishing date:

    June 10, 2008

    Over the last 15 years, altimetry satellites have been poring over the oceans in every detail, collecting more data in 10 days than could be gathered over several centuries by ships. This nascent revolution in oceanography promises to improve climate forecasting.

    Publishing date:

    June 3, 2008

    Satellite altimetry is the only space-based technology capable of penetrating below the ocean surface. This capability will benefit a broad range of ocean forecasting applications, now and in the future.

  6. Jason-2 takes to the air

    Publishing date:

    May 7, 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.

  7. Jason-2 all set for the off

    Publishing date:

    June 18, 2008

    The Jason-2 oceanography satellite is now in the home straight and set for launch Friday 20 June. Before reaching final orbit, the satellite will go through a sequence of steps just after launch and during the beginning-of-life phase of its mission. Jason-2 teams are watching launch preparations advance in California with much relief after a series of setbacks over the last 2 weeks. First, successive delays in the launch of the GLAST satellite pushed back the departure of Jason-2, since the same ground teams were preparing both satellites; and then poor weather prevented the satellite from being mated with the launcher as planned.
