| Zusammenfassung |
| The first five vibrationally excited states
of molecular nitrogen have been included in the Sheffield University
plasmasphere ionosphere model. Vibrationally excited molecular nitrogen reacts
much more strongly with atomic oxygen ions than ground-state nitrogen; this
means that more O+ ions are converted to NO+ ions, which
in turn combine with the electrons to give reduced electron densities. Model
calculations have been carried out to investigate the effect of including
vibrationally excited molecular nitrogen on the low-latitude ionosphere. In
contrast to mid-latitudes, a reduction in electron density is seen in all
seasons during solar maximum, the greatest effect being at the location of the
equatorial trough. |
