What is TOPEX/Poseidon data?

TOPEX/Poseidon data has revolutionized the way the global ocean is studied. For the first time, the seasonal cycle and other temporal variabilities of the ocean have been determined globally with high accuracy, yielding fundamentally important information for testing ocean circulation models.

What is the difference between TOPEX/Poseidon and Jason-1?

The primary TOPEX/Poseidon mission has actually been completed as of August 1995. The data set from this prime mission has provided oceanographers with the first global data set on the Earth's oceans. The Jason-1 mission of NASA/CNES (launch Dec. 7, 2001) is the follow-on to T/P.

How did TOPEX/Poseidon develop a map of ocean topography?

TOPEX/Poseidon used the global perspective available only from space to develop maps of ocean topography showing the barely perceptible hills and valleys of the sea surface. This effort significantly expanded the knowledge developed from shipboard research, which is limited to specific locations.

What happened to the TOPEX/Poseidon satellite?

• The TOPEX/Poseidon oceanography satellite, launched Aug. 10, 1992, ceased operations on Oct. 9, 2005, after nearly 62,000 orbits of Earth in 13 years of operations. The spacecraft's pitch reaction wheel stalled causing the loss of 3-axis stabilization (the ability to maneuver), hence the end of the mission.
