Sources of Polar Cap Poynting Flux and Particle Energy and their Relation to Neutral Density Disturbances
Abstract
DoD has a long-standing interest in neutral density variations in the upper atmosphere becausethese variations influence the ability to track and identify space objects, avoid collisions, predict re-entry,maintain control of satellite constellations, and mitigate the influence of atmospheric chemical andionization changes that accompany density perturbations. Episodic changes in neutral density aremodulated largely by the deposition of particle kinetic energy flux and Poynting flux and the loss of energyvia nitric oxide (NO) cooling. This project focuses on the source(s) and influence of polar-region energydeposition on neutral density.
