We have recently added a high-resolution global model of the lithospheric magnetic field derived from CHAMP and Swarm satellite observations to the Geosoft Geoscience Data Service (Powered by DAP).
LCS-1 is a global grid of the scalar magnetic field anomaly at Earth*#39;s surface (WGS84 ellipsod) on regular 0.25° x 0.25° grid in (geodetic) latitude and longitude, for spherical harmonic degrees n=14-185.*#0160; This data can be useful when studying super-regional trends, and as a backdrop on which to level and combine smaller-footprint terrestrial surveys. The LCS-1 data show features similar to those exhibited by the WDMAM2 and EMM2015 lithospheric field models truncated at degree 185 in regions where they include near-surface data, and provides unprecedented detail where they do not.
