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.

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 ...

Cross Correlation Between Plasmaspheric Hiss Waves and Enhanced Radiation Levels at Aviation Altitudes

Space Weather
Enhanced radiation in the Earth's atmosphere can pose serious hazards to pilots, aircraft passengers, and commercial space travelers. Recent results have shown, statistically, that there is a strong correlation between dose rates observed by Automated ...

Enhanced Radiation at Aviation Altitudes and Plasmaspheric Hiss Waves—A Time Shift Analysis

Journal of Geophysical Research: Space Physics
Abstract Increased radiation levels in Earth's atmosphere can present significant risks to airline pilots, passengers, and commercial space travelers. Recent findings have revealed a strong statistical link between radiation dose rates detected at aviation altitudes (km) and plasmaspheric hiss wave power observed along the same ...

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.

Determining the Temporal and Spatial Coherence of Plasmaspheric Hiss Waves in the Magnetosphere [PDF]

Journal of Geophysical Research: Space Physics, 2021
AbstractPlasmaspheric 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. There is growing evidence that the temporal and spatial variability of wave‐particle interactions are important factors in the ...

Nightside Plasmaspheric Plume‐To‐Core Migration of Whistler‐Mode Hiss Waves

Geophysical Research Letters, 2022
AbstractWhistler‐mode hiss waves play an important role in the radiation belt electron depletion. Whether the hiss waves with significant differences in amplitude and propagation direction within the plasmaspheric core and plume are related to each other remains unclear.

Unique Banded Structures of Plasmaspheric Hiss Waves in the Earth's Magnetosphere

Journal of Geophysical Research: Space Physics, 2023
AbstractPlasmaspheric 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 a broadband emission with frequencies from ∼100 Hz to several kHz, here we report Van Allen

Statistical Relationship Between Exohiss Waves and Plasmaspheric Hiss

Geophysical Research Letters, 2020
AbstractBased on the Van Allen Probe A observations from 2013 to 2015, we show the statistical relationship between exohiss waves and plasmaspheric hiss. Both hiss and exohiss waves have higher occurrence rates on the dayside (MLT = 8–20) and are positively correlated.

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 ...
