AB: Anthropogenic radiation in the kHz range (VLF) is present throughout much of the inner magnetosphere and has been shown to play a significant role in enhancing the pitch-angle diffusion of energetic particles (> ~ 0.5 MeV) in the inner radiation belts and increasing the net particle loss rate. Over the last 30 years, much work has been performed to model the distribution of VLF waves throughout the inner magnetosphere. The present study compares results from the recently developed AFRL 3D raytracing code AMPTRACE with a ducted propagation model [Inan, et al, JGR, 1984], as well as wave data from the IMAGE and OGO satellites.
