The satellite has started a globe-circling voyage to monitor sea level, a vital indicator of global climate change.
Compared with Jason-1, Jason-2 will provide substantially more accurate data and thus will improve knowledge of global and regional sea-level changes, and enable more precise weather, ocean and climate forecasts.
Jason-2’s expected lifetime of at least three years will extend into the next decade the continuous record of these data started in 1992 by NASA and CNES, with the TOPEX/Poseidon mission.
