Theoretical, Diagnostic and Empirical Ionospheric Model Development, and Wave Signatures in Upper Atmosphere Density.

Abstract

To provide a better description of the ionospheric environment studies have been undertaken ranging from the expansion of scope of a theoretical ionospheric model, event modeling studies, and studies of new applications-oriented empirical models. The Phillips Laboratory Global Theoretical Ionospheric Model has been rewritten to solve for multiple ion densities, and physical drivers have been updated. A theoretical model has been used to study latitudinal symmetry in equatorial electron densities related to scintillation, ionospheric responses to substorms, the role of neutral winds at night, and the means by which F region parameters may be derived from satellite in Situ measurements. A model has been applied to the study of disturbed ionospheric conditions. Finally, on the applications side, studies were conducted showing that a new simple profile model has powerful ray tracing applications and can be used to combine satellite measurements into full profiles. GPS satellites offer an opportunity for monitoring scintillations. Finally, SETA density measurement have been extensively utilized to both investigate and subsequently describe a series of wavelike and disturbed-conditions phenomena.
