Physical mechanisms of compressional EMIC wave growth [PDF]
Journal of Geophysical Research: Space Physics, 2010 On 29 June 2007, electromagnetic ion cyclotron (EMIC) waves were observed on the ground by the Canadian Array for Realtime Investigations of Magnetic Activity (CARISMA) network of magnetometers between L = 4 and L = 6 in response to a significant magnetospheric compression.

Association Between EMIC Wave Occurrence and Enhanced Convection Periods During Ion Injections
Geophysical Research Letters, 2020 Electromagnetic ion cyclotron (EMIC) waves tend to occur during geomagnetic storms and solar wind pressure pulses. However, they have also been regularly observed even in the absence of these two drivers.

Frontiers in Astronomy and Space Sciences, 2021 The cold plasmaspheric plasma, the ring current and the radiation belts constitute three important populations of the inner magnetosphere. The overlap region between these populations gives rise to wave-particle interactions between different plasma ...

Ionospheric Modulation by EMIC Wave‐Driven Proton Precipitation: Observations and Simulations
Journal of Geophysical Research: Space Physics, 2023 AbstractProtons of tens of keV can be resonantly scattered by electromagnetic ion cyclotron (EMIC) waves excited in the magnetosphere, resulting in proton precipitation down to the upper atmosphere. In this study, we report for the first time the ionospheric height‐dependent ionization in response to EMIC‐associated isolated proton aurora (IPA) using ...

The modulation of electromagnetic ion cyclotron waves by Pc 5 ULF waves [PDF]
Annales Geophysicae, 2009 The modulation of electromagnetic ion cyclotron (EMIC) waves by longer-period ULF waves has been proposed as a method for producing pearl structured Pc 1–2 EMIC waves.

Journal of Geophysical Research: Space PhysicsAbstractElectromagnetic ion cyclotron (EMIC) waves are believed to cause the loss of relativistic electrons from the outer radiation belt into the atmosphere due to pitch angle scattering. However, it is still unclear whether all EMIC waves can scatter relativistic electrons or which conditions are favorable for pitch angle scattering by EMIC waves. In
