Model of lifetimes of the outer radiation belt electrons in a realistic magnetic field using realistic chorus wave parameters

摘要: The outer radiation belt electrons in the inner magnetosphere show high variability during geomagnetically disturbed conditions. Quasi-linear diffusion theory provides both a framework for global prediction of particle loss at different energies and an understanding dynamics populations. It has been recently shown that pitch angle scattering due to wave-particle interaction with chorus waves modeled realistic magnetic field may be significantly from those estimated dipole model. In this work, we present lifetimes 1 keV–2 MeV computed Tsyganenko 89 model night, dawn, prenoon, postnoon local time (MLT) sectors levels geomagnetic activity distances. are also compared We develop lower band upper wave models each MLT sector using recent statistical studies amplitude, normal angle, spectral density distributions as functions latitude, distance, Kp index. increase plasma trough increasing latitude is included. obtained electron parameterized can used 2-D/3-D/4-D convection tracing codes.
