Low Frequency ULF Waves in the Earth’s Inner Magnetosphere: Statistics During Coronal Mass Ejections and Seeding of EMIC Waves

Abstract Here we perform a statistical analysis of low frequency ultra-low-frequency (ULF) waves (mHz-Hz) in the Earth’s inner magnetosphere excluding electromagnetic ion cyclotron (EMIC) waves concurrently observed. We use the magnetic field data from the two Van Allen Probes during their first magnetic local time (MLT) revolution that cover the periods of coronal mass ejections. The major results of our analysis are as follows. (1) Spectra of both the transverse and compressional ULF waves are well approximated by the po ...

Generation of EMIC Waves Observed by Van Allen Probes at Low L Shells

Observation of linearly polarized He+-band electromagnetic ion cyclotron (EMIC) waves at low L shells is a new, and quite unexpected, result from the Van Allen Probes mission. Here we analyze the two EMIC wave events observed by Van Allen Probes at low L shells and put forward a new-generation mechanism for the low-L EMIC waves. Both events were observed at L \~ 3 but one of them has a discrete spectrum near the O+ gyrofrequency and its second harmonic, whereas the second event has a broad spectrum between the O+ gyrofrequen ...

Model of electromagnetic ion cyclotron waves in the inner magnetosphere

The evolution of He+-mode electromagnetic ion cyclotron (EMIC) waves is studied inside the geostationary orbit using our global model of ring current (RC) ions, electric field, plasmasphere, and EMIC waves. In contrast to the approach previously used by Gamayunov et al. (2009), however, we do not use the bounce-averaged wave kinetic equation but instead use a complete, nonbounce-averaged, equation to model the evolution of EMIC wave power spectral density, including off-equatorial wave dynamics. The major results of our stud ...
