Abstract
Substantial progress has been made in modeling the geopotential field since the last reporting period (Anderle, 1979a). Models of the gravity potential show improvement across the entire gravitational spectrum with resolution down to 1° haIf‐wavelength. Major sources of data utilized for advancing our knowledge of the geopotential field consist of satellite laser ranging (Smith, 1982; Wilson, 1979; Linder, 1981) which contributed to the long wavelength portion of the spectrum, satellite altimetry (GEOS‐3, 1979; SEASAT, 1981) and improved surface gravity anomalies (Rapp, 1981b) both of which contributed to the intermediate and short wavelength features of the spectrum. Uniform global distribution of data in combination solutions is generally achieved by using altimeter data over the ocean and terrestrial gravity anomalies over land.
