The origins of Birkeland currents
Reviews of Geophysics, 1983A qualitative explanation is proposed for the main features of quiet‐time Birkeland currents. The major conclusions are as follows: (1) The source of region 1 currents is the interplanetary electric field, linked to the polar ionosphere directly along open field lines near noon but indirectly, via the plasma sheet, at most other longitudes.

Observations of Birkeland currents at auroral latitudes
Reviews of Geophysics, 1975After many years of languishing interest, field‐aligned currents (Birkeland currents) are now regarded as an important link between the magnetosphere and the ionosphere. We describe techniques that are used to measure them and then discuss in some detail measurements that have been interpreted as indicating the presence of Birkeland currents.
