Jason 3 ready to take over crucial ocean monitoring role

In early October, the Jason-3 ocean-monitoring satellite will take over from Jason-2 as the reference source of global sea surface height measurements from space. Find out why Jason-3 is so important by watching a live-streamed transatlantic briefing about the satellite on 19 September at 1600 (CEST) and ask questions via Twitter #askjason3.

The Jason-3 ocean-monitoring satellite was launched on 17 January this year.

After months of carefully checking its instruments and the quality of the data it is sending back to Earth, Jason-3 is now being readied to take over from its predecessor Jason-2 as the reference source of high-precision measurements of the global sea surface height from space.

Why is this important? Because the Jason satellites, and their precursor Topex/Poseidon, have played a crucial role in our understanding of the weather, the climate and the impacts of climate change.

This record of high-precision measurements of the sea surface height began in 1992 and Jason-3 is expected to ensure it continues uninterrupted until 2021.
Online Jason-3 briefing

At 16:00 (CEST) on 19 September, representatives of all of the Jason-3 programme partners – EUMETSAT, the French Space Agency (CNES), the US’s National Oceanic and Atmospheric Administration (NOAA) and National Aeronautics and Space Administration (NASA) and the EU – will give a transatlantic briefing about this key programme and be available to answer your questions via Twitter.

The European Commission funds European contributions to the satellite’s operations as part of the EU’s flagship Earth observation environmental programme, Copernicus. Within Copernicus, Jason-3 will provide essential data for the Copernicus Marine Environment Monitoring Service (CMEMS) and it is the reference mission for calibrating observations of sea surface height collected by the Copernicus Sentinel-3 satellites.

The live stream of the briefing will be available here on the day of the event.

Taking part in the briefing are:

• Richard Gilmore, from the European Commission’s Directorate General for Internal Market, Industry, Entrepreneurship and SMEs (DG GROW)
• François Parisot, EUMETSAT Altimetry Manager and Jason-3 Project Manager
• Philippe Escudier, CNES Oceanography Programme Manager
• Pierre-Yves Le Traon, from the Copernicus Marine Environment Monitoring Service and Mercator Ocean Scientific Director
• Josh Willis, NASA JPL Jason-3 Project Scientist
• Laury Miller, NOAA Jason-3 Program Scientist

The briefing will take place at EUMETSAT’s headquarters in Darmstadt, Germany, with Josh Willis and Laury Miller joining via video link from the US.
