Ocean Surface Topography Products from Jason-3
The interagency Jason-3 mission is a joint efforts by four organizations to measure sea surface height by using a radar altimeter mounted on the low-earth orbiting satellite Jason-3. The four mission participants are:
This satellite altimetry mission provides sea surface heights for determining ocean circulation, climate change and sea-level rise. The Jason-3 satellite is the follow-on to the research satellites TOPEX/Poseidon, Jason-1, and Jason-2 and is instrumental in meeting NOAA's operational need for sea surface height measurements necessary for ocean modeling, forecasting El Niño / La Niña events, and hurricane intensity prediction.
CNES, EUMETSAT, NOAA and NASA built their fourth joint spacecraft Jason-3, launched January 17, 2016 at 10:42 AM PST (1:42 PM EST), to continue the collection of sea-surface elevation measurements, work that began with the Topography Experiment (TOPEX)/Poseidon mission. Launched in August 1992, the TOPEX/Poseidon satellite used a Radar Altimeter, microwave radiometer, precision satellite tracking, and precision orbit determination as part of a worldwide effort to study and describe global ocean dynamics in relation to Earth's environment and climate change. The success of TOPEX/Poseidon led the agencies to build Jason-1, and was followed on by Jason-2, which collected data from June 2008 until October 2019. Therefore, a decision was made to provide continuity of the ocean surface height dataset by launching the follow-on satellite Jason-3.
The Jason-3 operations are planned for 5 years, comprising the Routine Operations (3 years) and the Extended Routine Operations Phases (2 years).
NASA provided the launch services for the Jason-3 mission. The CNES Mission Operations Center was the primary control center during Launch and Early Orbit Phase (LEOP) and Checkout. Near real time products are created at NOAA Satellite Operation Facility and at EUMETSAT in Darmstadt Germany.
