Simulation of the outer radiation belt electrons near geosynchronous orbit including both radial diffusion and resonant interaction with Whistler‐mode chorus waves (2005, methodology): “This parameterization was found from a best fit of the sum of DLL M and DLL E - as given by equations (2) and (3)- to the DLL coefficients calculated by introducing the CRRES high-energy electron (MEA) data in a simplified version of Salammbô where only radial diffusion and friction were included.”
The dual role of ELF/VLF chorus waves in the acceleration and precipitation of radiation belt electrons (2007, background): “Similar association of acceleration periods with chorus have been observed from space (Meredith et al., 2002a, b; Miyoshi et al., 2003; Meredith et al., 2003b ).”
Resonant scattering of plasma sheet electrons leading to diffuse auroral precipitation: 2. Evaluation for whistler mode chorus waves (2011, methodology): “Typically, chorus amplitudes lie in the range 1–100 pT [Burtis and Helliwell, 1975; Meredith et al., 2003; Li et al., 2009a], however, amplitudes of ∼1 nT or above have been reported during intense geomagnetic activity [Parrot and Gaye, 1994; Cattell et al., 2008; Cully et al., 2008].”
Statistical analysis of relativistic electron energies for cyclotron resonance with EMIC waves observed on CRRES (2003, unknown): “…Li et al. , 1997; Elkington et al. , 1999; Summers and Ma , 2000a, 2000b; Hudson et al. , 2001; Li and Temerin , 2001; Mathie and Mann , 2001; Meredith et al. , 2001, 2002a, 2002b, 2003; O’Brien et al. , 2001; Friedel et al. , 2002; Summers et al. , 2002; Horne et al. , 2003; Miyoshi et al.…”
Corotating solar wind streams and recurrent geomagnetic activity: A review (2006, background): “…chorus is typically detected primarily close to the magnetic equator during substorms [Tsurutani and Smith, 1974], the sensitive wide band receiver and multichannel analyzers [Kimura et al., 1990] detected chorus during a magnetic storm in the off-equatorial regions as well [Miyoshi et al., 2003].”
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): “Various observational studies [e.g., Meredith et al., 2002a, 2002b, 2003b; Miyoshi et al., 2003; Smith et al., 2004; Iles et al., 2006] provide evidence for chorus-driven electron acceleration to relativistic energies in regions outside the plasmasphere during geomagnetically disturbed periods.”
A microscopic and nanoscopic view of storm‐time chorus on 31 March 2001 (2004, background): “waves, in turn, can accelerate the electrons in the Earth’s outer radiation belt to relativistic energies [Meredith et al., 2003] causing radiation damage to Earth orbiting spacecraft.”
THEMIS observations of long‐lived regions of large‐amplitude whistler waves in the inner magnetosphere (2008, methodology): “resonant interactions with whistler-mode waves [Horne and Thorne, 2003; Meredith et al., 2003].”
Time dependent radial diffusion modeling of relativistic electrons with realistic loss rates (2004, background): “Since the outer zone maximum is typically observed near L = 5 under quiet conditions [e.g., Meredith et al., 2003b ], an outer zone quiet-time lifetime between 1–10 days would seem to be most appropriate.”
Radiation Belt Environment model: Application to space weather nowcasting (2008, background): “Several studies have shown an association between relativistic electron flux enhancements and prolonged periods of enhanced chorus amplitudes lasting for the order of several days [ Meredith et al., 2002, 2003a; Miyoshi et al., 2003].”
Energization of relativistic electrons in the presence of ULF power and mev microbursts: Evidence for dual ULF and VLF acceleration (2003, background): “Later, the solar connection was refined when Paulikas and Blake [1979] established that solar wind velocity was well correlated with trapped energetic electron fluxes.”
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 ”
Energetic outer zone electron loss timescalesduring low geomagnetic activity (2006, background): “However, electron minimum resonant energies are only observed to fall below 2 MeV in the region L > 4.5 when fpe/fce > 10 and largely occur on the duskside [Meredith et al., 2003c].”
