The wave distribution functions of plasmaspheric ELF hiss: GEOS 1 observation in the equatorial region

open access: yesThe wave distribution functions of plasmaspheric ELF hiss: GEOS 1 observation in the equatorial region
P(論文) The wave distribution functions of plasmaspheric ELF hiss have been determined at the equatorial region inside the plasmapause, by applying the maximum entropy method to the data observed by GEOS 1 satellite. Three equatorial events have been analyzed, and it is found that just inside the plasmapuse, the wave normal direction θ of ELF hiss is ...

Novel Wave Models and Diffusion Coefficients for Plasmaspheric Hiss and Low Frequency Hiss

2021 International Conference on Electromagnetics in Advanced Applications (ICEAA), 2021
The Earth's inner magnetosphere is populated by a host of high frequency plasma waves which, via wave-particle interactions, can shape the dynamics of the terrestrial radiation belts. One of these is an incoherent whistler-mode plasma wave commonly referred to as hiss.

Whistlers and plasmaspheric hiss: Wave directions and three‐dimensional propagation

Journal of Geophysical Research: Space Physics, 1993
Wave data from the DE 1 satellite showing simultaneously nonducted whistlers and hiss are analyzed to determine wave propagation directions. At L = 3.8 and a geographic latitude of λg = 12°S, the average wave normal directions of discrete whistlers are measured to be ∼51° for fnof;= 4.5 kHz and ∼60° for fnof;= 3.5 kHz, forming a small (<20°) angle ...

Precipitation Loss of Radiation Belt Electrons by Two‐Band Plasmaspheric Hiss Waves

Journal of Geophysical Research: Space Physics, 2020
AbstractA two‐band plasmaspheric hiss consisting of a low‐frequency band (normal hiss with the frequency below 2 kHz) and a high‐frequency band (locally generated hiss with the frequency up to 10 kHz) was observed on 6 January 2014 by the Van Allen Probes (He et al., 2019, https://doi.org/10.1029/2018GL081578).

Determining the global coherence of plasmaspheric hiss waves in the magnetosphere

2020
&lt;p&gt;Plasmaspheric hiss waves is important in the radiation belt. Previous papers have shown that considering the variability of wave parameters will improve the effectiveness of modeling wave-particle interactions in the Radiation Belt, but less is known about how rapidly (and by how much) wave characteristics vary.

CIMI simulations with newly developed multiparameter chorus and plasmaspheric hiss wave models

Journal of Geophysical Research: Space Physics, 2017
AbstractNumerical simulation studies of the Earth's radiation belts are important to understand the acceleration and loss of energetic electrons. The Comprehensive Inner Magnetosphere‐Ionosphere (CIMI) model considers the effects of the ring current and plasmasphere on the radiation belts to obtain plausible results.

Global Survey of Electron Precipitation due to Hiss Waves in the Earth’s Plasmasphere and Plumes

Journal of Geophysical Research: Space Physics, 2021
AbstractWe present a global survey of energetic electron precipitation from the equatorial magnetosphere due to hiss waves in the plasmasphere and plumes. Using Van Allen Probes measurements, we calculate the pitch angle diffusion coefficients at the bounce loss cone, and evaluate the energy spectrum of precipitating electron flux. Our ∼6.5‐year survey
