Novel Wave Models and Diffusion Coefficients for Plasmaspheric Hiss and Low Frequency Hiss

The Earth's inner magnetosphere is populated by a host of high frequency plasma waves which, via wave-particle interactions, can shape the dynamics of the terrestrial radiation belts. One of these is an incoherent whistler-mode plasma wave commonly referred to as hiss. Hiss is nearly always present in the inner magnetosphere, acting to diffusively scatter electrons into the atmosphere. While hiss waves are often low amplitude, their persistence allows them to wear away at the radiation belts, carving out new slot regions over days to weeks.
