Global Geomagnetic Model Errors as a Function of Altitude and Geomagnetic Activity

Space Weather
The errors of global geomagnetic models, such as the International Geomagnetic Reference Field and the World Magnetic Model (WMM), are well‐characterized at the Earth's surface, but their error behavior as a function of altitude and geomagnetic activity ...
