Attenuation of plasmaspheric hiss associated with the enhanced magnetospheric electric field [PDF]

Annales Geophysicae, 2021
We report an attenuation of hiss wave intensity in the duskside of the outer plasmasphere in response to enhanced convection and a substorm based on Van Allen Probe observations.

Effect of plasma density on diffusion rates due to wave particle interactions with chorus and plasmaspheric hiss: extreme event analysis [PDF]

Annales Geophysicae, 2014
Wave particle interactions play an important role in controlling the dynamics of the radiation belts. The purpose of this study is to estimate how variations in the plasma density can affect diffusion rates resulting from interactions between chorus ...

On How High-Latitude Chorus Waves Tip the Balance Between Acceleration and Loss of Relativistic Electrons. [PDF]

Geophys Res Lett, 2019
Modeling and observations have shown that energy diffusion by chorus waves is an important source of acceleration of electrons to relativistic energies.

Identification of Locally Generated Plasmaspheric Hiss

Geophysical Research Letters
In this study, we statistically analyze the wave properties of plasmaspheric hiss using data from the Van Allen Probes. The magnetic power spectral densities of hiss waves exhibit dependence on magnetic local time, geomagnetic activity, and the L‐shell ...

Global Model of Plasmaspheric Hiss From Multiple Satellite Observations [PDF]

Journal of Geophysical Research: Space Physics, 2018
AbstractWe present a global model of plasmaspheric hiss, using data from eight satellites, extending the coverage and improving the statistics of existing models. We use geomagnetic activity dependent templates to separate plasmaspheric hiss from chorus.

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.

Evolution of dayside chorus into nightside plasmaspheric hiss

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 ...

Long Lifetime Hiss Rays in the Disturbed Plasmasphere

Geophysical Research Letters
Plasmaspheric hiss waves are important to shape the Earth’s electron radiation belt. These waves are commonly envisioned to have a long lifetime which allows them to permeate the global plasmasphere from a spatially restricted source.

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.

Electron scattering by whistler‐mode ELF hiss in plasmaspheric plumes [PDF]

Journal of Geophysical Research, 2008
Nonadiabatic loss processes of radiation belt energetic electrons include precipitation loss to the atmosphere due to pitch‐angle scattering by various magnetospheric plasma wave modes. Here we consider electron precipitation loss due to pitch‐angle scattering by whistler‐mode ELF hiss in plasmaspheric plumes.
