Van Allen Probes observation of plasmaspheric hiss modulated by injected energetic electrons [PDF]

Annales Geophysicae, 2018
Plasmaspheric hiss was observed by Van Allen Probe B in association with energetic electron injections in the outer plasmasphere. The energy of injected electrons coincides with the minimum resonant energy calculated for the observed hiss wave ...

Evolution of dayside chorus into nightside plasmaspheric hiss [PDF]

Frontiers in Astronomy and Space Sciences
Plasmaspheric hiss is an incoherent, broadband, whistler-mode emission that is found primarily in the Earth’s dense plasmasphere and is believed to be largely responsible for the formation of the slot region between the inner and outer radiation belts ...

A Generation Mechanism of Banded Plasmaspheric Hiss

Geophysical Research Letters
As a unique structure of plasmaspheric hiss emissions, banded hiss waves generally consist of an upper band above ∼200 Hz, a lower band below ∼100 Hz and a power gap in between. However, the generation mechanism of banded hiss remains unclear.

The distribution of plasmaspheric hiss wave power with respect to plasmapause location

Geophysical Research Letters, 2016
In this work, Van Allen Probes data are used to derive terrestrial plasmaspheric hiss wave power distributions organized by (1) distance away from the plasmapause and (2) plasmapause distance from Earth.

Determining the temporal and spatial coherence of plasmaspheric hiss waves in the magnetosphere [PDF]

, 2021
Plasmaspheric hiss is one of the most important plasma waves in the Earth's magnetosphere to contribute to radiation belt dynamics by pitch‐angle scattering energetic electrons via wave‐particle interactions.

Multi‐parameter chorus and plasmaspheric hiss wave models [PDF]

, 2021
The resonant interaction of energetic particles with plasma waves, such as chorus and plasmaspheric hiss waves, plays a direct and crucial role in the acceleration and loss of radiation belt electrons that ultimately affect the dynamics of the radiation ...

Unique Banded Structures of Plasmaspheric Hiss Waves in the Earth’s Magnetosphere [PDF]

, 2023
Plasmaspheric hiss is an electromagnetic wave mode that occurs ubiquitously in the high-density plasmasphere and contributes crucially to the dynamic behavior of the Earth’s Van Allen radiation belts. While plasmaspheric hiss is commonly considered to be

Early-Time Non-Equilibrium Pitch Angle Diffusion of Electrons by Whistler-Mode Hiss in a Plasmaspheric Plume Associated with BARREL Precipitation

Frontiers in Astronomy and Space Sciences, 2021
In August 2015, the Balloon Array for Radiation belt Relativistic Electron Losses (BARREL) observed precipitation of energetic (<200 keV) electrons magnetically conjugate to a region of dense cold plasma as measured by the twin Van Allen Probes ...

An empirical model of the global distribution of plasmaspheric hiss based on Van Allen Probes EMFISIS measurements

Earth and Planetary Physics, 2020
Using wave measurements from the EMFISIS instrument onboard Van Allen Probes, we investigate statistically the spatial distributions of the intensity of plasmaspheric hiss waves.
