The predominant part of the geomagnetic field, as observed at the Earth’s surface, originates from sources in the Earth’s core and, to a lesser degree, in the Earth’s crust. Spatial distribution and secular variation of this internal part were described, e.g., by Schmucker (1985).

Reviews of Geophysics, 1972
The purpose of this review is to outline the definition and method of derivation of the indices of geomagnetic activity that are most commonly used at present. The first part of the review presents the methods of derivation of Kp, ap, AE, and Dst; the second part involves a discussion of the strengths and weaknesses of each index.
