• Global model of lower band and upper band chorus from multiple satellite observations (2012, background): “In contrast, upper band chorus is largely confined to within about 6 of the magnetic equator at all local times due to stronger Landau damping at higher frequencies [Bortnik et al., 2007].”

• The Electric and Magnetic Field Instrument Suite and Integrated Science (EMFISIS) on RBSP (2013, background): “Nightside chorus is strongest inside L = 8, and is also confined to latitudes below 15◦, due to strong Landau damping of oblique waves during their propagation towards higher latitude from the equatorial source region (Bortnik et al. 2007).”
• Dynamic evolution of energetic outer zone electrons due to wave‐particle interactions during storms (2007, background): “Our assumption of field-aligned propagation is probably realistic for nightside chorus, since Landau damping rapidly removes waves with propagation vectors inclined at more than 30 to the ambient magnetic field [ Bortnik et al., 2007a ] and confines such waves to latitudes within about 15 of the equ”

• Helium, Oxygen, Proton, and Electron (HOPE) Mass Spectrometer for the Radiation Belt Storm Probes Mission (2013, background): “Their wave normal angle controls the direction of propagation, but the suprathermal plasma distributions control the Landau damping of the waves and therefore how far off the equator they will propagate (Bortnik et al. 2007) as illustrated in Fig.”
• Statistical properties of plasmaspheric hiss derived from Van Allen Probes data and their effects on radiation belt electron dynamics (2015, background): “…because during active times, suprathermal electron fluxes are larger on the nightside, which causes stronger Landau damping of whistler mode waves [Bortnik et al., 2007; Li et al., 2010] and thus limits the ability of chorus waves to propagate into the plasmasphere and evolve into plasmaspheric…”
