TL;DR: In this paper, the ionospheric contribution of the polar wind and cleft ion fountain at energies less than 10 eV has been added to previously measured sources; this total ion outflow has then been used to calculate the resulting ion density in the different internal regions of the earth's magnetosphere: plasmasphere, plasma trough, plasma sheet, and magnetotail lobes.

TL;DR: In this paper, a new computational model has been created to describe the interaction of auroral electrons with the atmosphere, which is used to compute energy spectrums, ionization rates, backscatter ratios, and optical emissions associated with different incident electron spectrums.

TL;DR: A comprehensive review of the characteristics of theta aurora as revealed from four imaging efforts with the DE 1 and 2 satellites can be found in this article, where the dominant electrons and ions and the associated flow directions into and out of the various regions of the pole, similarities between the transpolar arc and the auroral oval are discussed.

TL;DR: In this article, low-energy ionospheric ions, injected into the magnetosphere at the dayside cleft, are studied using data from the retarding ion mass spectrometer (RIMS) experiment on the Dynamics Explorer 1 satellite.

TL;DR: A large number of data on suprathermal O(+) ions taken during the retarding ion mass spectrometer (RIMS) experiment aboard the DE 1 satellite are surveyed in this article.
