Abstract  A comprehensive statistical analysis on 8 years of lowerband chorus wave packets measured by the Van Allen Probes and THEMIS spacecraft is performed to examine whether, when, and where these waves are above the theoretical threshold for nonlinear resonant waveparticle interaction. We find that \~5\textendash30\% of all chorus waves interact nonlinearly with \~30 to 300keV electrons possessing equatorial pitch angles of >40\textdegree in the outer radiation belt, especially during disturbed (AE>500 nT) periods with energetic particles associated with injections from the plasma sheet. Such considerable occurrence rates of nonlinear interactions imply that the evolution of energetic electron fluxes should be dominated by nonlinear effects, rather than by quasilinear diffusion as commonly assumed. We discuss the possible consequences of such a large amount of highamplitude chorus waves and examine their characteristics that can influence the efficiency of nonlinear waveparticle interactions.
