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

Journal of Geophysical Research: Space Physics, 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.

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

Journal of Geophysical Research: Space Physics, 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

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.

Modeling the Leakage of Hiss Waves From the Plasmasphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract Plasmaspheric hiss waves can cross the plasmasphere boundary layer (PBL) and leak into the plasmatrough, serving as the main source of exohiss waves. However, it remains unclear how the PBL and wave characteristics affect the leakage process of hiss waves. In this study, we conducted a detailed parametric ray tracing study to model the leakage

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.

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 ...

Frequency‐Dependent Latitudinal Distributions of Plasmaspheric Plume Hiss Directionality and Amplitude

Geophysical Research Letters
Plasmaspheric plume hiss plays a crucial role in shaping Earth's electron radiation belts and influencing magnetosphere–ionosphere energy coupling. However, its generation mechanism remains contested between cyclic‐linear and localized‐nonlinear models ...

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.

Analysis of plasmaspheric hiss wave amplitudes inferred from low-altitude POES electron data: Technique sensitivity analysis [PDF]

Journal of Geophysical Research: Space Physics, 2015
A novel technique capable of inferring wave amplitudes from low-altitude electron measurements from the Polar Operational Environmental Satellites (POES) spacecraft has been previously proposed to construct a global dynamic model of chorus and ...
