Comparison of gravimetric geoids with GEOS 3 altimetric geoidThe paper examines how well GEOS 3 radar altimeter estimates of geoid height compare with data from independently determined gravimetric geoids. To this end, GEOS 3 altimeter estimates of geoid height are compared with 1 by 1 deg gravimetric geoids in the North Atlantic, Northwest Pacific, and Indian oceans. There exist constant offsets and long-wavelength discrepancies between the two sets of data. Although some difficulties exist with constant offset and long-wavelength discrepancies, the GEOS 3 radar altimeter appears to detect geological features such as deep-sea trenches and is an excellent instrument for acquiring measurements of the shape of the ocean surface.
