Evaluation of Geodetic Products Produced by the NSWC Reduction of SEASAT Radar Altimeter Data.

Abstract

An estimation is made of the possible errors associated with the processing by NSWC of raw SEASAT altimetry data to produce ocean geodetic data, e.g. geoid heights and vertical deflections. Also the noise level of the SEASAT radar altimetry is estimated. Then the SEASAT geodetic data are examined for self-consistency on repeat-track sequences and compared with other independent geodetic data obtained from ocean gravity surveys by ships. Anomalies in the comparisons are examined to determine probable causes. (Author)
