(Un)Explained EMIC Waves: Understanding Quiet Time EMIC Wave Drivers

Journal of Geophysical Research: Space Physics
Abstract Electromagnetic ion cyclotron (EMIC) waves are known to be generated through cyclotron resonance with the local ion particle population and grow when there is a large enough temperature anisotropy. In general, these temperature anisotropies necessary for wave growth are found to be associated with either solar wind pressure ...

Spatial Distribution and Wave Property of Dual‐Frequency EMIC Waves: Swarm Observations

Journal of Geophysical Research: Space Physics
Abstract The spatial distributions of single‐frequency and dual‐frequency Electromagnetic ion cyclotron (EMIC) waves in the subauroral ionosphere are investigated under varying geomagnetic activities, using high‐resolution magnetic field data from dual Swarm satellites spanning from 2015 to 2017.

Quasi‐Periodic EMIC Waves and Pulsating Ionospheric Perturbations Related to ULF Waves

Journal of Geophysical Research: Space Physics
Abstract Pulsating proton auroras are often attributed to periodic proton precipitation. However, how the proton precipitation is periodically generated in the magnetosphere remains an open issue. Utilizing multi‐point space‐borne and ground‐based observations, this study proposed a potential mechanism responsible for pulsating proton

EMIC waves around the plasma-pause region

Planetary and Space Science, 2008
Abstract Electromagnetic ion-cyclotron (EMIC) instability has been studied using the general loss-cone distribution function by investigating the trajectories of charged particles and using the method of particle aspect analysis. A low β (ratio of plasma pressure to magnetic pressure) plasma consisting of resonant and non-resonant particles has ...

Statistical Dependence of EMIC Wave Scattering on Wave and Plasma Parameters

Journal of Geophysical Research: Space Physics, 2020
AbstractA recent statistical study (Qin et al., 2018, https://doi.org/10.1029/2018JA025419) has suggested that not all electromagnetic ion cyclotron (EMIC) waves can scatter relativistic electrons. However, knowledge of the factors that influence the EMIC wave scattering efficiency is still limited in observations.

Sub‐MeV Electron Precipitation Driven by EMIC Waves in Plasmaspheric Plumes at High L Shells

Journal of Geophysical Research: Space Physics
Electromagnetic ion cyclotron (EMIC) waves are known to be efficient for precipitating >1 MeV electrons from the magnetosphere into the upper atmosphere. Despite considerable evidence showing that EMIC‐driven electron precipitation can extend down to sub‐
