Report discusses relationship between degree of development of waves and sea-state bias in radar altimetry. Purpose of study to increase accuracy of estimates of sea-state bias and thereby increase accuracy of estimates of sea level obtained if waves at measurement spot suppressed. Study shows sea-state bias related to parameter called "pseudo wave age."
The technique of satellite altimetry is discussed. The complexity of the procedure for attaining highly accurate measurements of the sea level, and the need for a multidisciplinary approach are emphasized. Progress in oceanographic research is reviewed, with the emphasis on results from Skylab and the GEOS-3 missions, as well as from Seasat whose altimeter was the first one designed for oceanographic applications. The challanges that lie ahead, including improving the overall measurement accuracy of altimeter observations, and the development of new techniques for utilizing the altimeter data, are formulated. Future plans for the satellite altimeter systems, Topex/Poseidon and ERS-1.
