Welcome to the CCAR Global Near Real-Time Alongtrack Altimetry Viewer. This page allows you to view one day of alongtrack data of the sea surface height from the Jason, TOPEX/POSEIDON(T/P), Geosat Follow-On(GFO), ERS-2 and Envisat missions, if available. The altimeter data has been filtered to retain only short wavelength ocean mesoscale signals. Data is usually available within 12 to 36 hours of overflight. See Satellite Dates for more information.

This page is hosted by the Colorado Center for Astrodynamics Research (CCAR) at the University of Colorado, Boulder.
