Shock-induced disappearance and subsequent recovery of plasmaspheric hiss

Abstract:

Plasmaspheric hiss is an important whistler-mode emission controlling the evolution of radiation belt electrons, whose generation mechanism remains under debate. Here we investigate the shock-induced disappearance and subsequent recovery of plasmaspheric hiss using the coordinated observations of the Van Allen Probes (RBSP), the Time History of Events and Macroscale Interactions during Substorm (THEMIS), and the Polar Orbiting Environmental Satellites (POES) missions on 27 February 2014. These multi-point observations both inside and outside the plasmasphere allow a deep understanding of the generation mechanism of plasmaspheric hiss.
