 Abstract: [...] We develop a regularizing solution procedure accounting for recent theoretical stability estimates. The capabilities of the procedure are shown for a single magnetic field component of the spherical harmonic field expansion beginning from the year 1900 by varying the mantle conductivity model and the degree of smoothness in the regularization. As an example, the radial component of a global (5,5) core-mantle boundary field is calculated for two epochs.
