TOPEX/Poseidon was launched in 1992 as a joint effort between JPL's Ocean Topography Experiment (TOPEX) and France's Poseidon project. The satellite has a 1340-km orbit and carries several radar altimeters and other instruments to correct and calibrate the altimeters. The altimeters are not imaging sensors, but the satellite's data are used to generate global cycles every 10 days with an accuracy of 3 cm. There are four products generated from TOPEX/Poseidon data: significant wave height, sea surface anomaly, wind speed, and water vapor content.
TOPEX/Poseidon data can be found through the following:
