Large amplitude (>100 mV/m) whistler mode waves have been reported in Earth's Van Allen radiation belt [Cattell et al., Geophys. Res. Lett. 35, L01105, 2008]. These earlier observations were limited in their ability to fully characterize the properties of the waves due to their spacecraft trajectories and measurement abilities, resulting in an ongoing debate on the exact characteristics and importance of these waves in energizing the particles of the radiation belt. The Electric and Magnetic Field Instrument Suite and Integrated Science (EMFISIS) investigation on the twin Van Allen Probes spacecraft launched in August 2012 includes the plasma wave instruments (Waves) that simultaneously measure three orthogonal components of the wave magnetic field and the three orthogonal components of the wave electric field from ~10 Hz to 12 kHz at very high time resolution. This increased capability provides an opportunity to investigate these large amplitude waves in greater detail than previous missions. The characteristics of the largest amplitude waves detected by the EMFISIS search coil magnetometers, including their wave propagation characteristics and fine structure will be discussed and compared to previous observations by other spacecraft.
