• Energetic outer zone electron loss timescalesduring low geomagnetic activity (2006, background): “…by a combination of enhanced inward radial diffusion driven by ULF waves [e.g., Elkington et al., 1999; Liu et al., 1999; Hudson et al., 2000] and local, chorus-driven acceleration outside the plasmapause [e.g., O’Brien et al., 2003; Horne et al., 2006; Summers et al., 2005; Varotsou et al., 2005].”
• Simulation of the outer radiation belt electrons near geosynchronous orbit including both radial diffusion and resonant interaction with Whistler‐mode chorus waves (2005, background): “[21] Chorus acceleration has mostly been associated with flux increases at L 4.5 [Horne et al., 2005; O’Brien et al., 2003].”
• The dual role of ELF/VLF chorus waves in the acceleration and precipitation of radiation belt electrons (2007, background): “Follow-up studies have shown that the distribution of microbursts in MLT is similar to that of chorus, peaking in the dawn sector (O’Brien et al., 2003) in association with geomagnetic storms, and further that losses are 10–100 times greater during the main phase of the storm than during the recover”
• Timescale for radiation belt electron acceleration by whistler mode chorus waves (2005, background): “Indeed, several studies have shown that relativistic electron flux enhancements are associated with prolonged substorm activity, an elevated flux of seed electrons, and prolonged periods of enhanced chorus amplitudes lasting for the order of several days [Meredith et al., 2002a, 2003a; Miyoshi et a”
• 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): “relativistic electron flux in the outer radiation belt reported by Onsager et al. [2002], Green et al.”
• Nonlinear interaction of energetic electrons with large amplitude chorus (2008, background): “…at L = 5 since this is the region where the largest amplitude chorus waves are present [Cully et al., 2008], maximum inferred internal acceleration occurs [Green and Kivelson, 2004], and microbursts are most prevalent [e.g., O’Brien et al., 2003], all presumably due to interactions with chorus.”
• Quantification of relativistic electron microburst losses during the GEM storms (2004, background): “Of these, the latter has been closely identified with a particular variety of bursty 1 MeV precipitation observed at low altitude typically on the dawn side beyond the plasmasphere [O’Brien et al., 2003; Horne and Thorne, 2003].”
• Multidimensional quasi‐linear diffusion of radiation belt electrons (2005, background): “Radial diffusion, particularly when enhanced during storm times, is a potentially crucial source of energization [O’Brien et al., 2003] and also serves to redistribute locally accelerated particles [Green and Kivelson, 2004].”
• Differences between CME‐driven storms and CIR‐driven storms (2006, methodology): “The ULF power was provided by Paul O’Brien [O’Brien et al., 2003].”
• Time dependent radial diffusion modeling of relativistic electrons with realistic loss rates (2004, background): “indicate that both of these processes operate in different regions of the outer radiation zone [O’Brien et al., 2003].”
• Timescales for radiation belt electron acceleration and loss due to resonant wave-particle interactions: 1. Theory (2007, background): “…there is evidence that an additional local acceleration mechanism (e.g., VLF chorus diffusion) is required to explain the observed relativistic electron flux increases in the region 3 < L < 5 [e.g., O’Brien et al., 2003; Miyoshi et al., 2003, 2004; Shprits and Thorne, 2004; Iles et al., 2006].”
