        abstract:  EMAG2v3 is a global Earth Magnetic Anomaly Grid compiled from satellite, ship, and airborne magnetic measurements. It is a significant update of the previous release of the Earth Magnetic Anomaly Grid. The resolution remains 2 arc-minutes, and the altitude of 4 km above the geoid is still supported, but an additional product, a grid that is observed at sea-level over oceanic regions, has been produced. New additions grid and track line data have been included, both over land and the oceans. Wherever available, the original shipborne and airborne data were used instead of precompiled oceanic magnetic grids. Interpolation between sparse track lines in the oceans was improved by using a kriging algorithm, which specializes in heterogeneous data distribution gridding, in order to create a compilation as true to the observed data as possible, and avoid using a priori information. The longest wavelengths (>300 km) were replaced with the latests satellite lithosphere magnetic field model, MF7.
        purpose:  Magnetic anomaly maps provide insight into the subsurface structure and composition of the Earth's crust. Over continental areas, magnetic anomalies illuminate geologic, tectonic, and geothermal evolution of crust and lithosphere. In the world's oceans, anomalies trending parallel to the isochrons (lines of equal age) reveal the temporal evolution of oceanic crust. Magnetic maps are widely used in the geological sciences and in resource exploration.
