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.

Disappearance of plasmaspheric hiss following interplanetary shock [PDF]

Geophysical Research Letters, 2015
AbstractPlasmaspheric hiss is one of the important plasma waves controlling radiation belt dynamics. Its spatiotemporal distribution and generation mechanism are presently the object of active research. We here give the first report on the shock‐induced disappearance of plasmaspheric hiss observed by the Van Allen Probes on 8 October 2013. This special

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.

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 ...

Global statistical evidence for chorus as the embryonic source of plasmaspheric hiss [PDF]

Geophysical Research Letters, 2013
The origin of plasmaspheric hiss, the electromagnetic emission responsible for the gap between the inner and outer radiation belts, has been debated for over four decades. Recently, a new theory proposed that chorus, which is excited in the equatorial region outside the plasmapause, can propagate to low altitudes on the dayside and evolve into ...

Exohiss wave enhancement following substorm electron injection in the dayside magnetosphere [PDF]

Earth and Planetary Physics, 2018
Exohiss is a low-frequency structureless whistler-mode emission potentially contributing to the precipitation loss of radiation belt electrons outside the plasmasphere.

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.

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 ...

Variability of Quasilinear Diffusion Coefficients for Plasmaspheric Hiss [PDF]

Journal of Geophysical Research: Space Physics, 2019
AbstractIn the outer radiation belt, the acceleration and loss of high‐energy electrons is largely controlled by wave‐particle interactions. Quasilinear diffusion coefficients are an efficient way to capture the small‐scale physics of wave‐particle interactions due to magnetospheric wave modes such as plasmaspheric hiss.

Multi‐Parameter Chorus and Plasmaspheric Hiss Wave Models [PDF]

Journal of Geophysical Research: Space Physics, 2020
AbstractThe 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 belts.
