The scattering of electrons via plasmaspheric hiss whistler-mode plasma; waves has profound consequences for the dynamics of electrons in the; inner terrestrial magnetosphere, including the radiation belts.; Consequently, simulations of inner magnetospheric electron dynamics; incorporate hiss wave models, though these models are often; parameterized by quantities convenient to describe particle populations; (e.g. L-shell). However, recent studies have revealed that the spatial; distribution of plasmaspheric hiss wave power is only weakly dependent; on L-shell. Instead, it is dictated by the density structure of the; plasmasphere (including radial extent and azimuthal structure). In this; work, we create a plasmaspheric hiss wave model, and corresponding; particle diffusion coefficients, parameterized by plasmapause location; instead of L-shell, in order to quantify the importance of including; plasmapause-organization of hiss waves for inner magnetosphere models.; Significant differences in electron scattering lifetimes are found when; comparing L-shell parameterized hiss and plasmapause-parameterized hiss; wave models on the timescales of days. This implies that; plasmapause-parameterization of hiss waves may be important for modeling; specific geomagnetic events.
