Determining the magnetic field in the earth's deep mantle by an inverse boundary value problem

Year: 2012

Type: report

Abstract: [...] We develop a regularizing solution procedure accounting for recent theoretical\nstability estimates. The capabilities of the procedure are shown for a single magnetic\nfield 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.
