AB: Understanding the dynamics of the Earth's outer radiation belt is important for better modeling and forecasting the intensities of energetic electrons in space. It is established that wave diffusion processes are responsible for loss and acceleration of electrons in the radiation belts. Several recent studies indicate pitch angle and energy cross-diffusion cannot be ignored when considering the total diffusive effects. In this study, we incorporate the electron energy and pitch angle cross diffusion into the current Radiation Belt Environment model and investigate its effects on the dynamics of radiation belt electrons.
