• Timescales for radiation belt electron acceleration and loss due to resonant wave-particle interactions: 1. Theory (2007, methodology): “Energy diffusion due to cyclotron resonance with chorus waves is a viable mechanism for generating relativistic electrons (>1 MeV) in the outer zone during storms [Summers et al., 1998, 2002, 2004a, 2004b; Roth et al., 1999; Summers and Ma, 2000; Horne et al., 2005a; Thorne et al., 2005a; Varotsou ”
• 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): “MeV electron precipitation loss due to chorus scattering could therefore be important during the main phase of a storm when densities are low [Thorne et al., 2005b].”
• Global distribution of whistler‐mode chorus waves observed on the THEMIS spacecraft (2009, background): “…and Thorne, 1998, 2003; Summers et al., 1998, 2002, 2007; Lorentzen et al., 2001; Meredith et al., 2002, 2003; O’Brien et al., 2004; Horne et al., 2005; Shprits et al., 2006; Thorne et al., 2005, 2007; Li et al., 2007], but better information is required on the global distribution of chorus waves.”
• Parameterization of radiation belt electron loss timescales due to interactions with chorus waves (2007, methodology): “[5] In this study we consider only lower band chorus in the region of 0600–1500 MLT, which is dominant in producing microburst scattering [Thorne et al., 2005b; Shprits et al., 2006b].”
• Dependence of the quasi‐linear scattering rates on the wave normal distribution of chorus waves (2009, background): “Pitch angle and energy diffusion codes accounting for mixed diffusion [Albert and Young, 2005; Tao et al., 2008 ], convective codes including pitch angle and/or energy diffusion [Jordanova et al., 2003; Jordanova and Miyoshi, 2005; Miyoshi et al., 2006; Fok et al., 2008], and three-dimensional diff”
• Observation of two distinct, rapid loss mechanisms during the 20 November 2003 radiation belt dropout event (2006, background): “[5] Quasi-linear estimates of the pitch angle scattering rates shows that whistler mode chorus waves could provide losses of the relativistic electrons on the timescale of a day [Albert, 2005; Horne et al., 2005b; Thorne et al., 2005].”
• Origin of energetic electron precipitation >30 keV into the atmosphere (2010, background): “during geomagnetic storms [Blake et al., 1996; Lorentzen et al., 2001a, 2001b; O’Brien and McPherron, 2003; O’Brien et al., 2004; Thorne et al., 2005].”
• Radiation belt dynamics: The importance of wave‐particle interactions (2010, background): “…controlled by scattering rates near the edge of the loss cone [Shprits et al., 2006c, 2006d], range from values near the minimum lifetime associated with strong diffusion (∼an hour) at energies below 10 keV [Ni et al., 2008] to values comparable to a day at MeV energies [Thorne et al., 2005].”
• The Electric and Magnetic Field Instrument Suite and Integrated Science (EMFISIS) on RBSP (2013, background): “Pitch-angle Scattering and Loss to the Atmosphere Energetic radiation belt electrons can be scattered into the loss cone and lost by collisions in the atmosphere during resonant interactions with whistler-mode chorus emissions (Thorne et al. 2005), plasmaspheric hiss (Lyons et al.”
• Space Weather Effects in the Earth’s Radiation Belts (2018, background): “The mechanisms that cause injections of the lower energy electrons into and through the slot region (see Russell and Thorne 1970) have been investigated by Thorne et al. (2005), Zhao and Li (2013), and Turner et al. (2015, 2016).”
• Energetic Particle Influence on the Earth’s Atmosphere (2015, background): “Microbursts form an important fraction of the precipitation and are able to deplete the radiation belt during days (Thorne et al. 2005).”
• Energetic outer zone electron loss timescalesduring low geomagnetic activity (2006, background): “[45] Loss by chorus waves, known as microburst precipitation, generally occurs outside the plasmapause in regions of lower density [Thorne et al., 2005a, 2005b; O’Brien et al., 2004].”
