Advances in Radiation Belt Physics: Challenges in Models and Observations

Session ID#: 72929

Session Description:
The energetic particles which form the Earth’s radiation belts are dynamically controlled by both microscopic and macroscopic acceleration, transport and loss processes. Recent spacecraft missions have provided unprecedented insights into the radiation belt response to driving conditions, and fast-increasing computational capabilities have allowed models to better explain these measurements. State-of-the-art models are now being used for radiation belt flux forecasting, as well as for studying more extreme scenarios for which fewer data are available. However, competing ideas for particle energisation and transport, and various physical and statistical modelling approaches, lead to the question, “what physics and processes are necessary to accurately predict radiation belt behaviour?” This session calls for all observational, modelling and theoretical contributions focussing on the radiation belts, and especially encourages efforts which contrast observational data with modelling results and vice versa, to help define the direction of radiation belt research into the space weather forecasting era.
