GriddedTopography2AtmospherePotentialCoefficients

Estimate interior and exterior potential coefficients for atmosphere above digital terrain models. Coefficients for interior $(1/r)^{n+1}$ and exterior ($r^n$) are computed. The density of the atmosphere is assumed to be (Sjöberg, 1998) \[ \rho_0\left(\frac{R}{R+h}\right)^\nu, \]where $R$ is the radial distance of the ellipsoid at each point, $h$ the radial height above the ellipsoid, $\rho_0$ is densitySeaLevel and nu $\nu$ is a constant factor. The density is integrated from radialLowerBound and upperAtmosphericBoundary above the ellipsoid. The radialLowerBound is typically the topography and can be computed as expression at every point from inputfileGriddedData.
