... There is no question about the source of ionospheric plasma , since it is created from the ambient neutral atmosphere by ionization. However, the source of magnetospheric plasma is a much more complicated question: although it seems obvious that both solar wind and ionosphere feed it, the relative importance of these two sources is unclear. ... Protons (H + ) are the primary ions in solar wind and one of the major components in ionospheric outflows, and thus not good indicators of their source. ...
