MAGNETIC FIELD MODEL MF5
Six years of low-orbit CHAMP satellite magnetic measurements have provided an exceptionally high-quality data resource for lithospheric magnetic field modeling. Our fifth generation satellite-only magnetic field model MF5 extends to spherical harmonic degree 100. As a result of careful data selection, extensive corrections, filtering and line-leveling, the model has low noise levels and can be safely evaluated at the Earth’s surface. The model is particularly suited for inferring large-scale structure and composition of the lithosphere.
