We present a statistical study of the characteristics of very large amplitudewhistler waves inside the terrestrial magnetosphere using waveform capture datafrom the Wind spacecraft as an addition of the study by Kellogg et al.,[2010b]. We observed 244(65) whistler waves using electric(magnetic) field datafrom the Wind spacecraft finding ~40%(~62%) of the waves have peak-to-peakamplitudes of >/- 50 mV/m(>/- 0.5 nT). We present an example waveform captureof the largest magnetic field amplitude (>/- 8 nT peak-to-peak) whistler waveever reported in the radiation belts. The estimated Poynting flux magnitudeassociated with this wave is >/- 300 microW/m^2, roughly four orders ofmagnitude above previous estimates. Such large Poynting flux values areconsistent with rapid energization of electrons. The majority of the largestamplitude whistlers occur during magnetically active periods (AE > 200 nT). Thewaves were observed to exhibit a broad range of propagation angles with respectto the magnetic field, 0{\deg} </- {\theta}_kB < 90{\deg}, which showed noconsistent variation with magnetic latitude. These results are inconsistentwith the idea that the whistlers are all generated at the equator, propagatingalong the magnetic field, and that the observed obliqueness is due topropagation effects. We also identified three types of electron distributionsobserved simultaneously with the whistler waves including beam-like,beam/flattop, and anisotropic distributions. The whistlers exhibited differentcharacteristics depending on the observed electron distributions. The majorityof the waveforms observed in our study have f/f_ce </- 0.5 and are observedprimarily in the radiation belts simultaneously with anisotropic electrondistributions.
