New Applications of the Phillips Laboratory. Theoretical Ionospheric Model and Studies of Neutral Density Waves
Abstract
Firstly, a series of new applications for the PHILLIPS Laboratory ionospheric model have been developed; a version has been prepared that allows restarts from specified background conditions, and runs have been made of both impulsive (e.g., storm onset) and periodic (e.g., atmospheric wave) perturbed conditions. Comparison studies are the subject of ongoing work. Secondly, tests of a new plasmaspheric model have been conducted with a view to merging it with the PL model in a new version of PRISM. Thirdly, the PL model has been applied to a study of the low latitude ionosphere involving comparisons of the observed longitudinal and seasonal morphology of irregularities. Next, a version of the model has been prepared that permits a study of the effects of substorms through modifications of the vertical drift and neutral wind fields. Case studies at different longitudes identified increases in TEC with substorm expansion phases and decreases with substorm subsidence. Finally, SETA measurements of neutral density variations have been utilized in a study of both small-scale (up to 2500 km) larger scale wave phenomena, including descriptions of diurnal and magnetic activity dependencies.
