Using statistical wave power spectral profiles obtained from CRRES and the latitudinal
distributions of wave propagation modeled by the HOTRAY code, a quantitative analysis has
been performed on the scattering of plasma sheet electrons into the diffuse auroral zone by
multiband electrostatic electron cyclotron harmonic (ECH) emissions near L= 6 within the
0000–0600 MLT sector. The results show that ECH wave scattering of plasma sheet
electrons varies from near the strong diffusion rate (timescale of an hour or less) during …

Using the statistical wave power spectral profiles obtained from CRRES wave data within
the 0000–0600 MLT sector under different levels of geomagnetic activity and a modeled
latitudinal variation of wave normal angle distribution, we examine quantitatively the effects
of lower band and upper band chorus on resonant diffusion of plasma sheet electrons for
diffuse auroral precipitation in the inner magnetosphere. Whistler mode chorus‐induced
resonant scattering of plasma sheet electrons is geomagnetic activity dependent, varying …
