Application of Satellite Radar Altimeter Data to the Determination of Regional Tidal Constituents and the Mean Sea Surface
A method has been developed to correct the systematic satellite ephemeris errors in satellite radar altimeter data over an extended extrapolation area, having first determined these errors in a reference region where an accurate gravimetric geoid and tide model are available.
The method has been applied using GEOS-3 altimeter data in the GEOS-3 Atlantic Ocean Calibration Area, using a portion of the Hatteras Abyssal Plain as the reference area, to derive the mean sea surface and five tidal constituents in the extrapolation region.
