    Annex-D-ERS-1-ALT-OPR-Product-CCT-Format.pdf

    This product aims at providing the users with geophysically corrected altimeter measures over ocean, including all the engineering corrections and all the geophysical corrections due to the troposphere, the ionosphere and the electromagnetic bias. In addition, the surface altitude over the ellipsoid is calculated, correcting for the surface elevation due to tides and geoid.
