Truncation of Poisson’s Integral in Upward and Downward Continuations of the Earth’s Gravity

Abstract

In this contribution, first the efficiency of the kernel modification techniques in the Poisson upward and downward continuation of gravity is investigated in light of reducing the far zone contribution. Second, the methods of determining the critical radius of the near zone cap are reviewed and discussed in terms of the convergence and the accuracy of the estimate for the far zone contribution.
