A statistical study of EMIC waves observed by Cluster: 1. Wave properties (2014, methodology): “However, previous studies using equatorially orbiting spacecraft, which have better midnight coverage, have shown a low occurrence in this region [i.e., Anderson et al., 1992a, 1992b; Fraser and Nguyen, 2001; Loto’aniu et al., 2005; Halford et al., 2010; Min et al., 2012; Keika et al., 2013].”
Global distribution of EMIC waves derived from THEMIS observations (2012, result): “These results mostly agree to the previous results [Anderson et al., 1992a, 1992b; Fraser and Nguyen, 2001].”
Localized aurora beyond the auroral oval (2007, background): “…link between the plasmaspheric plume and the detached afternoon arc suggests that the proton precipitation may be caused by resonant interaction between energetic ring current protons and EMIC waves that are preferentially generated in regions of cold plasmaspheric plasma [Fraser and Nguyen, 2001].”
Van Allen probes, NOAA, GOES, and ground observations of an intense EMIC wave event extending over 12 h in magnetic local time (2015, methodology): “Although several major statistical studies [e.g., Anderson et al., 1992a; Fraser and Nguyen, 2001] have indicated that the occurrence rate of EMIC waves in postmidnight local times are extremely low, a more detailed look at the observations of Anderson et al.”
Resonant scattering of outer zone relativistic electrons by multiband EMIC waves and resultant electron loss time scales (2015, background): “…by the ion composition and anisotropy [e.g., Kozyra et al., 1984; Horne and Thorne, 1994] and by the location with respect to the plasmapause [Fraser and Nguyen, 2001], EMIC waves can be generated in three distinct frequency bands below the hydrogen (H+), helium (He+), and oxygen (O+) ion…”
Statistical analysis of relativistic electron energies for cyclotron resonance with EMIC waves observed on CRRES (2003, methodology): “…electron number density (n e ) profiles, in the same format as the bottom panel in Figure 2, were examined for each orbit, and a distinct plasmapause was identified if a change of n e of greater than 10 cm (cid:5) 3 occurred over a radial distance of less than 0.5 R e [ Fraser and Nguyen , 2001].”
Propagation of electromagnetic ion cyclotron wave energy in the magnetosphere (2005, methodology): “: PROPAGATION OF EMIC WAVE ENERGY 6 of 10 A07214 that the EMIC waves were generated near the equator and propagated into higher magnetic field regions, consistent with earlier studies [e.g., Kaye and Kivelson, 1979; Fraser and Nguyen, 2001; Mursula et al., 2001].”
EMIC wave activity during geomagnetic storm and nonstorm periods: CRRES results (2010, background): “Nguyen between 0 and 2 Hz [ Fraser and Nguyen, 2001 ].”
Modeling radiation belt electron dynamics during GEM challenge intervals with the DREAM3D diffusion model (2013, background): “…the plasmasphere [Lyons et al., 1972; Lyons and Thorne, 1973; Abel and Thorne, 1998; Meredith et al., 2007], and electromagnetic ion cyclotron (EMIC) waves preferentially generated near the plasmapause [Fraser and Nguyen, 2001; Albert, 2003; Summers and Thorne, 2003; Loto’aniu et al., 2006].”
Relativistic electron pitch-angle scattering by electromagnetic ion cyclotron waves during geomagnetic storms (2003, background): “, 1998], and the location relative to the plasmapause [Fraser and Nguyen, 2001].”
Observation of two distinct, rapid loss mechanisms during the 20 November 2003 radiation belt dropout event (2006, background): “Such waves occur preferentially near the dusk sector, are very intense (1–10 nT) [Erlandson and Ukhorskiy, 2001; Fraser and Nguyen, 2001], and can drive strong pitch angle diffusion [Albert, 2003; Summers and Thorne, 2003] of relativistic electrons and energetic protons.”
Timescales for radiation belt electron acceleration and loss due to resonant wave‐particle interactions: 2. Evaluation for VLF chorus, ELF hiss, and electromagnetic ion cyclotron waves (2007, background): “The particular band of EMIC waves that is excited depends on the ion composition, level of geomagnetic activity, and spatial location [Fraser and Nguyen, 2001].”

The occurrence and wave properties of H+‐, He+‐, and O+‐band EMIC waves observed by the Van Allen Probes (2015, background): “As the waves propagate to higher magnetic latitudes, the wave vector also becomes oblique [e.g., Rauch and Roux, 1982; Thorne and Horne, 1997; Fraser and Nguyen, 2001; Hu et al., 2010].”
Global morphology and spectral properties of EMIC waves derived from CRRES observations (2014, background): “In contrast, helium band EMIC waves, which are observed between the oxygen ion gyrofrequency, fcO+ and fcHe+, are observed both inside and outside the plasmapause [Fraser and Nguyen, 2001].”
