Global Geomagnetic Field Models

The IGRF-12 and WMM15 are global magnetic field models which describe the geomagnetic main field using a set of spherical harmonic coefficients. The models are derived from geomagnetic data collected via satellite, geomagnetic observatories, aircraft and marine vessels. The models are the product of...

Description
Summary:The IGRF-12 and WMM15 are global magnetic field models which describe the geomagnetic main field using a set of spherical harmonic coefficients. The models are derived from geomagnetic data collected via satellite, geomagnetic observatories, aircraft and marine vessels. The models are the product of a collaborative effort between magnetic field modellers and the institutes involved in collecting and disseminating magnetic field data from satellites, geomagnetic observatories and surveys around the world. A description of the models, the model coefficients and software to evaluate the models are available from: http://www.ngdc.noaa.gov/geomag/WMM/DoDWMM.shtml and http://www.ngdc.noaa.gov/IAGA/vmod/igrf.html These models are crucial to the progress of AAS project 4092. A detailed metadata record for the World Magnetic Model is available from NOAA (National Oceanic and Atmospheric Administration) at the provided URL.
