Radiation Belt Dynamics II

Submit an Abstract to this Session



Session ID#: 32948

Session Description:
This session is focused on modeling and wave-particle interactions, as well as the inner zone and slot region. Despite being discovered almost 60 years ago, radiation belt dynamics are not comprehensively understood yet. It is of great scientific and practical interest to predict the dynamics of the Van Allen radiation belts to help improve space weather predictions, assisting the mitigation of hazardous space weather effects on spacecraft operations. Generally, it is understood that the Van Allen radiation belt dynamics arise from a delicate balance between acceleration, transport, and loss processes. Numerical simulation studies of the radiation belts are important to understand the acceleration and loss of energetic electrons. Thus, radiation belt models require accurate knowledge of wave-particle interactions in the inner magnetosphere. Therefore, this session is for contributions that analyze the dynamics of the radiation belts, and highlight recent advances in radiation belt modeling and understanding of wave-particle interactions.
