About Jason-2

The Ocean Surface Topography Mission (OSTM) on the Jason-2 satellite followed Jason-1 with similar characteristics and instruments to extend the continuous record of precise sea surface height measurements started in 1992 with the TOPEX/Poseidon mission and to improve weather and climate forecasting. Jason-2 was a joint mission of four partners: CNES, NASA, NOAA and EUMETSAT. Jason-2 was launched on June 20, 2008 from Vandenberg Air Force Base (California, USA) and was decommissioned on October 10, 2019.
Poseidon-3, the main instrument of the Jason-2 mission was provided by CNES and has the same general characteristics as Poseidon-2, but with lower instrumental noise and an improved algorithm for better tracking over land and ice.

Jason-2 applications

• Extending TOPEX/Poseidon and Jason-1 time series
• Develop ocean forecasting capabilities based on high-precision, near-real time measurements of ocean surface topography (operational oceanography)
• Determine the decadal variability of the large-scale ocean circulation
• Improve measurements of global sea level changes
• Improve tide and wave models
