Vertical component of the lithospheric magnetic field
... Using a new scalar data product from the latest readings of the CHAMP FGM magnetometer, we have resolved the lithospheric magnetic field to degree 120, corresponding to 333 km wavelength. The data were found to be sensitive to crustal field variations up to degree 150 (down to 266 km wavelength), bu ...
