SM13A:
Quantitative Understanding of Particle Dynamics in Earth's Radiation Belts II


Submit an Abstract to this Session


Session ID#: 61113

Session Description:
Understanding the build-up and decay of energetic particle fluxes in Earth's radiation belts, to the point of prediction, remains a fundamental goal of space physics. Our understanding and modeling have been greatly improved over the past few years, due in large part to observations by Van Allen Probes. It is now widely accepted that wave-particle interactions play a key role, and these effects are included in most models as quasi-linear diffusion. At the same time, the effects of nonlinear wave-particle interactions, localized nonlinear structures, large scale magnetic field irregularities, and other phenomena on particle motion remain largely unquantified. This session calls for observational, theoretical, or modeling work that quantitatively analyzes the particle dynamics in Earth's radiation belts, especially encouraging work that attempts to close the gap between these micro-physics effects on particle motion and the macroscopic behavior of the radiation belts.
