The Jason-3 satellite was launched Sunday evening, 17 January, from the Vandenberg Air Force Base in California, United States of America. Jason-3 will continue the time series of mean sea-level measurements that started in 1992 with the launch of the Topex-Poseidon satellite and continued with Jason-1 and -2.
The satellite's measurements of ocean waves and ocean surface topography will provide essential input to numerical forecasts of sea state and ocean currents and to other applications in the areas of marine meteorology and operational oceanography. Measurements will also be used in numerical prediction models that couple the atmosphere and the oceans and are used for seasonal forecasting.
Jason-3 is the result of an international partnership between EUMETSAT, the French Space Agency (CNES), the US National Oceanic and Atmospheric Administration (NOAA), the US National Aeronautics and Space Administration (NASA), and the European Union, which funds European contributions to Jason-3 operations as part of its Copernicus Programme.
Within Copernicus, Jason-3 is the reference mission for cross-calibrating Sentinel-3 observations of sea-surface height and the precursor to the future cooperative Sentinel-6/Jason-CS mission, which is also being implemented in partnership between Europe and the United States.
