| Abstract: | The spherical harmonic coefficients of the Earth’s gravitational potential are conveniently determined by integration of gravity
data or potential data (derived from satellite altimetry) over a sphere. The major problem of such a method is that the data,
given on the non-spherical surface of the Earth, must be reduced to the sphere.
A new integral formula over the surface of the Earth is derived. With this formula improved first order topographic corrections
to the spherical formulas are obtained. |
