Fox Thomas Skinner ---------------------------------------- Abstract: We have modeled the vibrational distribution of the N2+(A) and N2+(B) states for both the midlatitude and auroral terrestrial ionoospheres. Our models include transport of the N2+ excited state ions. For the auroral case, electron-induced fluorescence plays an important role in determining the vibrational distribution. For the sunlit ionosphere, solar fluorescence dominates at high altitudes. We compare our results to those obtained by Broadfoot [1971], Degen [1981], and Fox and Dalgarno [1985], and to the recent measurements of Morrison et al. [1999]. ---------------------------------------- Discipline Category: Ionosphere
