Radiation belt modelling is crucial for understanding, modelling, and forecasting hazardous relativistic electron fluxes in the inner magnetosphere. However, these models often rely on statistical descriptions of wave processes. This includes ULF wave driven radial diffusion, which plays a key role in the energisation, loss, and transport of radiation belt electrons.
In this overview I will highlight how radial diffusion can be significantly misrepresented during storm times by existing empirical models and discuss how we can provide more realistic and accurate descriptions of storm time radial diffusion. The discussion will address how the following issues are critical factors in quantifying radial diffusion:
I hope that the overview will enable discussions around how we can improve statistical models of radial diffusion for use in radiation belt models and operational forecasting.
