Magnetospheric geomagnetic coordinates for space physics data presentation and visualization

Abstract

Corrected geomagnetic coordinates, which account for the multipolar geomagnetic field, are frequently used to organize the ionospheric-altitude data. However, realistic organization of data measured simultaneously in the magnetosphere and ionosphere in a some sort of magnetic coordinate system requires a combination of the high-altitude external magnetic fields and the multipolar low-altitude field. Such combinations have been non-existent in the past. A new magnetospheric geomagnetic coordinate system is introduced providing such a combination.
