"We present a method for imaging the global crustal magnetic field at Earth's surface using a local basis representation and a minimum norm model regularization approach. The local basis consists of a spherical triangle tessellation (STT) parametrization of the radial component of the crustal field at Earth's reference spherical surface," scientists in Zurich, Switzerland report.
"The Green's function for Laplace's equation in spherical geometry with Neumann boundary conditions provides the necessary forward modelling scheme. We solve the inverse problem of estimating the crustal field from satellite magnetic observations by minimizing an objective function ...
