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

Determining Plasmaspheric Densities from Observations of Plasmaspheric Hiss [PDF]

Journal of Geophysical Research: Space Physics, 2018
AbstractA new method of inferring electron plasma densities inside of the plasmasphere is presented. Utilizing observations of the electric and magnetic field wave power associated with plasmaspheric hiss, coupled with the cold plasma dispersion relation, permits calculation of the plasma density.

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.

Frequency‐Dependent Responses of Plasmaspheric Hiss to the Impact of an Interplanetary Shock

Geophysical Research Letters, 2021
Plasmaspheric hiss waves are essential for the pitch‐angle scattering and precipitation of energetic electrons and interplanetary shocks may affect these waves.

Deep learning model of hiss waves in the plasmasphere and plumes and their effects on radiation belt electrons

Frontiers in Astronomy and Space Sciences, 2023
Hiss waves play an important role in removing energetic electrons from Earth’s radiation belts by precipitating them into the upper atmosphere. Compared to plasmaspheric hiss that has been studied extensively, the evolution and effects of plume hiss are ...

Plasmaspheric hiss properties: Observations from Polar [PDF]

Journal of Geophysical Research: Space Physics, 2015
AbstractIn the region between L = 2 to 7 at all Magnetic Local Time (MLTs) plasmaspheric hiss was detected 32% of the time. In the limited region of L = 3 to 6 and 15 to 21 MLT (dusk sector), the wave percentage detection was the highest (51%). The latter plasmaspheric hiss is most likely due to energetic ~10–100 keV electrons drifting into the dusk ...

Generation of unusually low frequency plasmaspheric hiss [PDF]

2014 XXXIth URSI General Assembly and Scientific Symposium (URSI GASS), 2014
Plasmaspheric hiss is an incoherent, broadband electromagnetic whistler-mode emission, preferentially and steadily observed inside high-density plasmasphere and storm-time plasmaspheric plume [1-2]. The frequency of plasmaspheric hiss typically ranges between ∼200 Hz and 2 kHz, with peak wave power in a few 100s Hz.

Hot plasma effects on the dispersion properties of plasmaspheric hiss and its electron diffusion

地球与行星物理论评, 2023
Electron diffusion caused by plasmaspheric hiss is an important mechanism for the loss of electrons in Earth's inner magnetosphere; it has also been considered responsible for the formation of the slot region between inner and outer radiation belts.

Variability of Quasilinear Diffusion Coefficients for Plasmaspheric Hiss [PDF]

Journal of Geophysical Research: Space Physics, 2019
AbstractIn the outer radiation belt, the acceleration and loss of high‐energy electrons is largely controlled by wave‐particle interactions. Quasilinear diffusion coefficients are an efficient way to capture the small‐scale physics of wave‐particle interactions due to magnetospheric wave modes such as plasmaspheric hiss.

Van Allen Probes observation of plasmaspheric hiss modulated by injected energetic electrons [PDF]

Annales Geophysicae, 2018
Plasmaspheric hiss was observed by Van Allen Probe B in association with energetic electron injections in the outer plasmasphere. The energy of injected electrons coincides with the minimum resonant energy calculated for the observed hiss wave ...
