“…Primary outputs of the model are density n , temperature T , and parallel velocity v ∥ of the outflowing H + , He + and O + ions. The model considers the contributions from all ion distributions, including nonthermal or nonisotropic distributions such as ion conics, transversely accelerated ions, ion beams, upwelling ions, upflowing ions, or shell‐like distributions [ Klumpar , 1979; Hultqvist , 1983; Yau et al , 1984, 1985; Moore et al , 1986; Thelin et al , 1990; Kondo et al , 1990; Peterson et al , 1992; Miyake et al , 1993; André et al , 1994; Joko et al , 2004]. However, previous observations have revealed that such nonthermal or nonisotropic distributions do not always occur [e.g., Yau et al , 1984; Thelin et al , 1990; Kondo et al , 1990].…”
