Abstract
This chapter focuses on the origin of the plasmaspheric hiss (PH) emission, and in particular, considers whether chorus could be the embryonic source of PH. It describes the ray-tracing model used to study chorus wave propagation. The chapter mainly focuses on more recent observations that still raise puzzling questions regarding the origin of PH. It then shows that PH has a lower frequency boundary, and that, at least in some instances, chorus could not be the source of the PH power and that it would necessarily need to be excited locally. The chapter also shows a coincident observation between THEMIS-E and one of the newly launched Van Allen Probes (RB-B) that showed simultaneous chorus and hiss emissions. These emissions were very well correlated but occurred at much higher L-shells than predicted by our ray-tracing model.
