• EMIC wave activity during geomagnetic storm and nonstorm periods: CRRES results (2010, result): “The majority of the EMIC waves observed during storms were found in the main phase, which is consistent with previous Freja [Braysy et al., 1998], GOES [Fraser et al., 2010], and other satellite study results [Blum et al., 2009; Horne et al., 2009; Spasojevic and Fuselier, 2009] as well as with mode”
• Origin of energetic electron precipitation >30 keV into the atmosphere (2010, background): “On the other hand, electromagnetic ion cyclotron waves generally resonate with >500 keV electrons which appears too high in energy [Horne and Thorne, 1998; Summers and Thorne, 2003; Jordanova et al., 2008; Miyoshi et al., 2008].”
• Van Allen probes, NOAA, GOES, and ground observations of an intense EMIC wave event extending over 12 h in magnetic local time (2015, background): “Most theoretical studies have focused on the effectiveness of storm time dusk sector EMICwaves in high-density regions for pitch angle scattering relativistic electrons [e.g., Summers and Thorne, 2003; Summers et al., 2007a, 2007b; Jordanova et al., 2008; Chen et al., 2011].”

• Global characteristics of electromagnetic ion cyclotron waves: Occurrence rate and its storm dependence (2013, background): “[3] EMIC waves can interact with radiation belt electrons via Doppler-shifted cyclotron resonance and cause the pitch angle scattering of the electrons and their loss into the atmosphere [e.g., Thorne and Kennel, 1971; Lyons and Thorne, 1972; Horne and Thorne, 1998; Summers et al., 1998; Friedel et ”
