• On the storm‐time evolution of relativistic electron phase space density in Earth's outer radiation belt (2013, background): “Since EMIC waves are often generated during magnetospheric compressions [e.g., Usanova et al., 2008; 2012, and references therein], we also considered the possibility of EMIC-related loss of MeV electrons to the atmosphere.”
• Resonant scattering of outer zone relativistic electrons by multiband EMIC waves and resultant electron loss time scales (2015, methodology): “While the intensity of EMIC waves varies with the level of geomagnetic activity and the spatial location [e.g., Usanova et al., 2012; Min et al., 2012; Meredith et al., 2014], in the present study, for simplicity, we have adopted a nominal intermediate amplitude of 1 nT for all three bands of EMIC…”
• Electron losses from the radiation belts caused by EMIC waves (2014, methodology): “[1992a] and Usanova et al. [2012]. The time-averaged intensities of the hydrogen and helium band EMIC waves as a function of L∗, MLT, and magnetic activity are shown in Figure 1.”
• Circulation of Heavy Ions and Their Dynamical Effects in the Magnetosphere: Recent Observations and Models (2014, background): “EMIC waves are excited by a ring current temperature anisotropy with characteristic amplitudes of up to 10 nT during geomagnetically active conditions (e.g., Cornwall 1965; Søraas et al. 1980; Usanova et al. 2008, 2012; McCollough et al. 2010).”
• Global characteristics of electromagnetic ion cyclotron waves: Occurrence rate and its storm dependence (2013, methodology): “The MLT gap was also found in the THEMIS data set [Min et al., 2012; Usanova et al., 2012], although theMLT extent of the gap is slightly narrower (ΔMLT ~2h).”
• The occurrence and wave properties of H+‐, He+‐, and O+‐band EMIC waves observed by the Van Allen Probes (2015, background): “Several studies [Anderson et al., 1992a; Kasahara et al., 1992; Halford et al., 2010; Min et al., 2012; Usanova et al., 2012, 2013; Keika et al., 2013; Meredith et al., 2014] have been performed that repeatedly show a peak in EMIC wave occurrence around the afternoon MLT sector, ~12:00<MLT ≤~18:00.”
• Global morphology and spectral properties of EMIC waves derived from CRRES observations (2014, methodology): “More recently, Usanova et al. [2012], using Time History of Events and Macroscale Interactions during Substorms (THEMIS) data together with an automated EMIC wave detection algorithm, found peak rates of the order 6–8% in the region 8 < L < 10 primarily in the noon and dusk sectors.”
