Storm-time variations of plasmaspheric ELF hiss
Journal of Atmospheric and Terrestrial Physics, 1982Abstract ELF and VLF observational data obtained from Intercosmos-3 (August 1970–November 1970) and Intercosmos-5 (December 1971–March 1972) satellites have been analyzed. During geomagnetic storms, the generation region of plasmaspheric hiss, which is usually located near the equatorial plane just within the plasmasphere, tends to move inwards ...

Mid-latitude and plasmaspheric hiss: A review
Planetary and Space Science, 1992Abstract A review of mid-latitude and plasmaspheric hiss-type emissions observed on ground-based stations and in the Earth's magnetosphere is presented. Different approaches to modelling of these emissions are discussed. It is pointed out that mid-latitude hiss emissions are most likely to be generated in the equatorial magnetosphere where the energy

Plasmaspheric hiss intensity variations during magnetic storms
Journal of Geophysical Research, 1974The storm time intensity variations of ELF electromagnetic emissions have been studied by using the Ogo 6 search coil magnetometer. Low-latitude signals exhibit a sharp low-frequency cutoff and are identified as plasmaspheric hiss. Such waves show pronounced intensification during the recovery phase of magnetic storms but remain close to background ...

Novel Wave Models and Diffusion Coefficients for Plasmaspheric Hiss and Low Frequency Hiss
2021 International Conference on Electromagnetics in Advanced Applications (ICEAA), 2021The 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.

A theoretical study of plasmaspheric hiss generation
Journal of Geophysical Research: Space Physics, 1983An investigation of the generation of plasmaspheric hiss by the whistler mode instability has been carried out. Using combined ray‐tracing and growth rate calculations, the path‐integrated growth rates of a large number of waves have been calculated using a distribution function of the form F ∝ E−n sinm α.

Plasmaspheric hiss overview and relation to chorus
Journal of Atmospheric and Solar-Terrestrial Physics, 2009A brief overview is given of the history of plasmaspheric hiss research, particularly in the context of the recent work by Bortnik et al. (2008) indicating that chorus could be the likely source of plasmaspheric hiss. Previous suggestions given in the literature for this theory are reviewed and then the mechanism itself is outlined, focusing on the ...

Plasmaspheric hiss observations in the evening and afternoon quadrants
Journal of Geophysical Research, 1975Data obtained with an Explorer-45 instrument for detecting the magnetic components of ELF signals propagating in the magnetosphere are examined, showing that the strongest, most persistent signals were plasmaspheric hiss from a few hundred to a few thousand Hertz. Broad-band signals of 25 milligamma were common.

On the field-aligned Poynting fluxes of plasmaspheric hiss
In this study, we investigate Poynting fluxes of plasmaspheric hiss waves using the Van Allen Probes wave observation. The hiss waves are identified based on the number density of cold plasma, wave frequency, ellipticity, wave normal angle, and planarity.Hui Zhu, Huicong Chen, Mingyue Lu
