TL;DR: A review of the most common magnetic coordinate systems and how they are defined, where they are used, and how to convert between them can be found in this paper, where the definitions are presented based on the spherical harmonic expansion coefficients of the International Geomagnetic Reference Field (IGRF) and, in some of the coordinate systems, the position of the Sun which we show how to calculate from the time and date.

TL;DR: In this paper, the morphology and dynamics of the electrical current systems of the terrestrial magnetosphere and ionosphere were reviewed, and the conditions under which the currents are expected to be weak, and hence minimally contaminate measurements of the internally produced magnetic field of the Earth, were briefly outlined.

TL;DR: In this paper, the authors acknowledge the use of NASA/GSFC's Space Physics Data Data and the Facility for OMNI data, and provide results provided by the Community Coordinated Modeling Center at Goddard Space Flight Center through their public Run on Request (ROP) system (http://ccmc.gsfc.nasa.gov).

TL;DR: In this article, the authors review the primary differences in the magnetic field at polar latitudes, and the consequences that these have for the magnetosphere-ionosphere-thermosphere coupling.
