| - Jason maps ocean surface topography. The data collected
provide information on ocean surface current velocity and
heights which, when combined with ocean models, can
lead to a four-dimensional description of ocean circulation.
Data from Jason are also extending ocean surface
topography into the 21st century, providing a 5-year view
of global ocean surface topography, increasing understanding
of ocean circulation, improving forecasting of
climate events, and measuring global sea-level change.
