Jason 1 is an Earth satellite designed to monitor global ocean circulation, study the ties between the oceans and atmosphere, improve global climate forecasts and predictions, and monitor events such as El Niño conditions and ocean eddies.
Like its predecessor, the Topex/Poseidon mission, Jason 1 is a joint mission of the United States and France. In 2008, a follow-on called the Ocean Surface and Topography Mission (OSTM/Jason 2) was launched to further Jason 1's studies. The two spacecraft now fly in tandem around Earth.
