Proton transport model in the ionosphere: 1. Multistream approach of the transport equations

摘要: The suprathermal particles, electrons and protons, coming from the magnetosphere precipitating into high-latitude atmosphere are an energy source of Earth's ionosphere. They interact with ambient thermal gas through inelastic elastic collisions. physical quantities perturbed by these precipitations, such as heating rate, electron production or emission intensities, can be provided in solving kinetic stationary Boltzmann equation. This equation yields particle fluxes a function altitude, energy, pitch angle. While this has been solved different ways for transport fully tested, proton is more complicated. Because charge-changing reactions, latter set two-coupled equations that must solved: one protons other H atoms. We present here new approach solves multistream proton/hydrogen encompassing collision angular redistributions magnetic mirroring effect. In order to validate our model we discuss conservation compare another under same inputs rocket observations. influence discussed forthcoming paper.
