• Observation of two distinct, rapid loss mechanisms during the 20 November 2003 radiation belt dropout event (2006, background): “…density, such as the plasmapause or plasmaspheric drainage plumes, they become highly unstable to EMIC wave growth, resulting in EMIC waves that scatter relativistic electrons (Figure 7b) and protons into the bounce and drift loss cones [e.g., Jordanova et al., 2003; Lorentzen et al., 2000].”
• Substorm dependence of plasmaspheric hiss (2004, background): “Recent theoretical and experimental work has shown that EMIC waves may indeed play an important role in the loss of relativistic electrons during enhanced geomagnetic activity [Lorentzen et al., 2000; Albert, 2003; Meredith et al., 2003b; Summers and Thorne, 2003].”
• Outward radial diffusion driven by losses at magnetopause (2006, background): “…traverse the dusk side region of intense EMIC waves, but may produce very rapid precipitation events which are strongly localized in MLT. Precipitation due to EMIC waves may be also related to the bursts of hard X rays seen by balloon-borne instruments [Lorentzen et al., 2000; Millan et al., 2002].”
• Testing loss mechanisms capable of rapidly depleting relativistic electron flux in the Earth's outer radiation belt (2004, background): “Also, what mechanism caused the electrons to be scattered and precipitated into the atmosphere? Several mechanisms have been suggested which could explain the observed precipitation, including scattering due to increased field line curvature and interaction with waves such as electron cyclotron harm”
• Quantification of relativistic electron microburst losses during the GEM storms (2004, background): “…under consideration are much shorter than the longer (minutes to hours) precipitation phenomena that have been tentatively associated with electromagnetic ion-cyclotron (EMIC) waves [Lorentzen et al., 2000; Millan et al., 2002], but which may also play a substantial role in electron losses.”
• Origin of energetic electron precipitation >30 keV into the atmosphere (2010, methodology): “istic precipitation associated with scattering by EMIC waves has been observed using X‐ray observations from balloons [Foat et al., 1998; Lorentzen et al., 2000; Millan et al., 2002] and using SAMPEX [e.”
• Electron scattering by whistler-mode ELF hiss in (2008, background): “Scattering by EMIC waves along the duskside plasmasphere can induce precipitation loss of MeV electrons on timescales of several hours to a day [Lorentzen et al., 2000; Summers and Thorne, 2003; Meredith et al., 2003b; Summers et al., 2007b].”
• Dynamics of the Earth’s Particle Radiation Environment (2009, background): “Moreover, scattering of relativistic electrons by EMIC waves can also drive the X-ray bursts in the ionosphere (Lorentzen et al. 2000; Millan et al. 2002, 2007).”
• Dynamic evolution of energetic outer zone electrons due to wave‐particle interactions during storms (2007, background): “In addition, recent studies [ Lorentzen et al., 2000, 2001; Millan et al., 2002; Thorne et al., 2005b] have shown that losses can occur on timescales comparable to or even shorter than those associated with acceleration processes.”
• Precipitation of radiation belt electrons by EMIC waves, observed from ground and space (2008, background): “It is predicted that precipitation of relativistic electrons takes place near the dusk-side plasmapause, where EMIC waves are typically generated by ions with energies of tens of keV [Cornwall et al., 1970; Erlandson and Ukhorskiy, 2001; Meredith et al., 2003; Jordanova et al., 2008], and observatio”
