The Downward Continuation of Potential Field Data

Proceedings, 2018
Summary Aeromagnetic data from ensemble and dyke models (and their derivatives) can be pseudo-downward continued by a factor alpha by raising the amplitude of the Fourier coefficients to a power alpha.

Downward continuation of constrained potential fields

Journal of Geophysical Research, 1973
Formal analytic solutions to a class of problems of downward continuation of potential fields into a homogeneous semi-infinite solid are given. The solid contains stationary sources below a fixed depth, and the potential field in the source-free slab is derived on the basis of given boundary values of the field and its vertical derivative.

Regularization of downward heat flow continuation

Studia Geophysica et Geodaetica, 1987
Some regularization approaches to downward heat flow continuation from the Earth's surface to the depth of interest are presented, provided the heat transfer is described by the homogeneous steady-state equation. The Fourier transform of horizontal coordinates is used and the relation between the regularization of the heat flow spectrum and the ...

On Discrete Schemes in Downward Continuation of Gravity

2005
Two discretization schemes of the Poisson integral have been proposed to date. Although they are mathematically solvable, they produce different gravity on the geoid for the same input data. This discrepancy arises because of different discretization techniques of the Poisson kernel; still, this problem has not received adequate attention. The question
