Fully analytic, low- and middle-latitude ionospheric model
A fully analytic ionospheric model emphasizing the low-latitude F region for various seasonal and solar-cycle conditions is presented. Features such as the post-sunset rise in the F-layer peak height and the 'equatorial anomaly' maxima in plasma density near + or - deg geomagnetic latitude are designed to closely approximate those in the semi-empirical low-latitude ionospheric model. Significant improvements are thus obtained over previous comparable analytic models. Numerical computations are also presented that demonstrate the importance of these large-scale plasma structures to the neutral dynamics of the low-latitude thermosphere. Equally significant effects are anticipated for the electrodynamic simulations of E region/F region coupling involving flux-tube integrated electrical conductivities.
