abstract = {The plasmasphere is filled with a plasma wave mode called hiss: a broadband superposition of whistler-mode waves. Hiss efficiently scatters electrons, facilitating their loss to the atmosphere and thereby playing a significant role in shaping inner magnetospheric electron populations, including the radiation belts.  For this reason, electron loss by hiss wave scattering is a critical component of computational models of the inner magnetosphere. 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 the L-shell. Instead, it is dictated by the density structure of the plasmasphere (including radial extent and azimuthal structure). We created a plasmaspheric hiss wave model (including low frequency component), and calculated corresponding particle diffusion coefficients, parameterized by plasmapause location instead of L-shell, and performed simulations using Versatile Electron Radiation Belts (VERB) code to quantify the importance of including plasmapause organization of hiss waves for inner magnetosphere models. Additionally, we explored machine learning techniques in order to create a classification model of the hiss waves presence and their low frequency component.}
