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.

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

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.

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.

Abrupt Disappearance of Plasmaspheric Hiss Inside the Magnetic Dip
Geophysical Research LettersPlasmaspheric hiss plays an important role in radiation belt electron dynamics, and its excitation and propagation have long attracted attention. During a substorm, Van Allen Probe B observed the disappearance of plasmaspheric hiss at the magnetic dip ...

The Relationship of Exohiss Waves With Plasmaspheric Hiss Distribution and Solar Wind Parameters
Journal of Geophysical Research: Space Physics, 2023 AbstractExohiss waves below 0.1 electron cyclotron frequency (fce) are structureless whistler‐mode emissions typically observed in the plasmatrough. Plasmaspheric hiss may possibly propagate from the plasmasphere into the plasmatrough and evolve into exohiss waves.

Competition between outer zone electron scattering by plasmaspheric hiss and magnetosonic waves [PDF]
Geophysical Research Letters, 2017 AbstractWe quantify the electron scattering effects of simultaneous plasmaspheric hiss and magnetosonic waves that occurred in two neighboring time intervals but with distinct wave intensity profiles on 21 August 2013. Their combined scattering is found capable of causing electron distribution variations largely distinguishable from the consequences of

Variation in Plasmaspheric Hiss Wave Power With Plasma Density
Geophysical Research Letters, 2018 AbstractPlasmaspheric hiss waves are commonly observed in the inner magnetosphere. These waves efficiently scatter electrons, facilitating their precipitation into the atmosphere. Predictive inner magnetosphere simulations often model hiss waves using parameterized empirical maps of observed hiss power. These maps nearly always include parameterization
