Based on a multi-instrumental Cassini dataset we make model versus observation comparisons of plasma number densities,nP= (nenI)1/2(neandnIbeing the electron number density and total positive ion number density, respectively) and short-lived ion number densities (N+, CH2+, CH3+, CH4+) in the southern hemisphere of Titan’s nightside ionosphere over altitudes ranging from 1100 and 1200 km and from 1100 to 1350 km, respectively. ThenPmodel assumes photochemical equilibrium, ion–electron pair production driven by magnetospheric electron precipitation and dissociative recombination as the principal plasma neutralization process. The model to derive short-lived-ion number densities assumes photochemical equilibrium for the short-lived ions, primary ion production by electron-impact ionization of N2and CH4and removal of the short-lived ions through reactions with CH4. It is shown that the models reasonably reproduce the observations, both with regards tonPand the number densities of the short-lived ions. This is contrasted by the difficulties in accurately reproducing ion and electron number densities in Titan’s sunlit ionosphere.
