AB: Bounce-averaged diffusion is a promising means of simulating the dynamics of radiation belt electrons. It is now becoming feasible, and necessary, to assess the results of different wave models and to compare the resulting dynamical particle distributions. This involves complications not fully addressed by previous, qualitative simulations. Here, we report progress on two technical aspects: the rapid and accurate approximation of quasilinear diffusion rates, for hiss, chorus and EMIC waves; and the extension to 3D while preserving the effects of energy/pitch angle cross diffusion under evolving conditions.
