Magnetic, global anomaly map

Abstract

In summary, with methods discussed above, it will be possible to regularly update the WDMAM model without excessive effort to reliably synthesize a map that accurately represents the world’s magnetic anomalies. This would also require information on the long-wavelength field in order to continuously improve representation of the world magnetic anomalies. The upcoming Swarm mission of the European Space Agency (http://www.esa.int/ esaLP/LPswarm.html) will considerably improve the lithospheric magnetic anomaly maps by providing highly accurate measurements of magnetic field gradients and further improve the long-wavelength anomalies in next generations of WDMAMs and EMAGs. It is our hope that these global magnetic anomaly maps will enjoy widespread usage, and inspire further aeromagnetic and marine surveys, thus helping to produce maps having truly global coverage. Finally, the WDMAM would not have existed without the willingness of institutions to constantly revise and release their national-scale compilation.
