Electron Diffusion by Coexisting Plasmaspheric Hiss and Chorus Waves: Multisatellite Observations and Simulations

Geophysical Research Letters, 2020
AbstractWe report a rare event of intense plasmaspheric hiss and chorus waves simultaneously observed at the same L shell but different magnetic local times by Van Allen Probes and Magnetospheric Multiscale. Based on the measured waves and electron distributions, we calculate the bounce‐averaged diffusion coefficients and subsequently simulate the ...

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

Journal of Geophysical Research: Space Physics, 2015
AbstractA 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 plasmaspheric hiss waves.

Simultaneous Evolutions of Inner Magnetospheric Plasmaspheric Hiss and EMIC Waves Under the Influence of a Heliospheric Plasma Sheet

Geophysical Research Letters, 2022
AbstractPlasmaspheric hiss and electromagnetic ion cyclotron (EMIC) waves are two of the most important magnetospheric plasma waves inside the Earth's high‐density plasmasphere. In this work, utilizing observations from the WIND and Van Allen Probes missions, we investigate the simultaneous evolutions of inner magnetospheric plasmaspheric hiss and EMIC

The Global Propagation of Hiss Waves Originating From Dynamic Plasmaspheric Plume

Geophysical Research Letters
Abstract Hiss waves play a critical role in shaping Earth's radiation belts and mediating magnetosphere‐ionosphere energy transfer. Intense hiss emissions are frequently generated within dynamic plasmaspheric plumes through linear and nonlinear wave‐particle interactions.

Evolution of Radiation Belt Electron Pitch Angle Distribution Due to Combined Scattering by Plasmaspheric Hiss and Magnetosonic Waves

Geophysical Research Letters, 2019
AbstractBoth magnetosonic (MS) waves and plasmaspheric hiss can resonantly scatter outer radiation belt electrons, leading to various electron pitch angle distribution. Based on electron diffusion coefficients calculations and 2‐D Fokker‐Planck diffusion simulations, we perform a parametric study to quantitatively investigate the net electron ...

Simultaneous disappearances of plasmaspheric hiss, exohiss, and chorus waves triggered by a sudden decrease in solar wind dynamic pressure

Geophysical Research Letters, 2017
AbstractMagnetospheric whistler mode waves are of great importance in the radiation belt electron dynamics. Here on the basis of the analysis of a rare event with the simultaneous disappearances of whistler mode plasmaspheric hiss, exohiss, and chorus triggered by a sudden decrease in the solar wind dynamic pressure, we provide evidences for the ...

Local Generation of High‐Frequency Plasmaspheric Hiss Observed by Van Allen Probes

Geophysical Research Letters, 2019
The generation of a high‐frequency plasmaspheric hiss (HFPH) wave observed by Van Allen Probes is studied in this letter for the first time. The wave has a moderate power spectral density (∼10−6 nT2/Hz), with a frequency range extended from 2 to 10 kHz ...

Acceleration of Electrons by Whistler-Mode Hiss Waves at Saturn. [PDF]

Geophys Res Lett, 2022
Plasmaspheric hiss waves at the Earth are well known for causing losses of electrons from the radiation belts through wave particle interactions. At Saturn, however, we show that the different plasma density environment leads to acceleration of the ...

Internal source of plasmaspheric hiss on Earth

地球与行星物理论评, 2022
Plasmasphere is an upward extension of the ionosphere at low and middle latitudes along the closed magnetic field lines rooted in the Earth, where the trapped whistler-mode waves in the frequency range from tens to thousands of Hertz are named as ...

The Study on Modeling of Global Plasmaspheric Hiss Amplitude Based on Deep Learning Algorithm

Space Weather, 2023
Plasmaspheric hiss waves make great significance on the loss of electrons in the Earth's radiation belts. The prediction and reconstruction for global evolution plasmaspheric hiss are critical to investigate the dynamic process of radiation belt. In this
