Closed Covariance Expressions for Gravity Anomalies, Geoid Undulations, and Deflections of the Vertical Implied by Anomaly Degree Variance Models.
Abstract : A new anomaly degree variance model is developed by considering potential coefficient information to degree 20, and updated values of the point anomaly variance, the 1 degree blockExpand

The Ohio State 1991 geopotential and sea surface topography harmonic coefficient models
The computation is described of a geopotential model to deg 360, a sea surface topography model to deg 10/15, and adjusted Geosat orbits for the first year of the exact repeat mission (ERM). ThisExpand

Use of potential coefficient models for geoid undulation determinations using a spherical harmonic representation of the height anomaly/geoid undulation difference
Abstract This paper suggests that potential coefficient models of the Earth's gravitational potential be used to calculate height anomalies which are then reduced to geoid undulations where suchExpand

Comparisons of global topographic/isostatic models to the Earth's observed gravity field
The Earth's gravitational potential, as described by a spherical harmonic expansion to degree 180, was compared to the potential implied by the topography and its isostatic compensation using fiveExpand

The development and analysis of geopotential coefficient models to spherical harmonic degree 360
The GEM-T2 potential coefficient model (incomplete to degree 50) has been combined, in a least squares sense, with 30 arc min mean anomalies, to obtain an adjusted set of coefficients and gravityExpand

The Earth's Gravity Field to Degree and Order 180 Using Seasat Altimeter Data, Terrestrial Gravity Data and Other Data,
Abstract : The spherical harmonic expansion of the earth's gravitational field has been obtained to degree 180 by combining several sources of data. The first data set was an a priori set ofExpand

The development of an isostatic gravitational model to degree 360 and its use in global gravity modelling
SUMMARY The determination of high-degree geopotential models currently requires accurate terrestrial gravity information on a global basis. For the regions where such information is unavailable orExpand
