Gravity Summary A general solution for the laplace problem can be written in spherical harmonics: V=(GM/r) n=0∞ m=0n (R/r)n (Cnm cos m + Snm sin m) Pnm (sin…

Gravity IV: Dipole moment of density anomaly: the ambiguity We want to know: But actually, gravity anomaly alone cannot provide this information. The ambiguity of a buried…

Gravity Summary In first approximation we can chose for the shape of the Earth an ellipsoid of rotation defined essentially by the degree n=2 m=0 of the potential field plus…
