Whistler Mode Wave-Driven Electron Scattering Properties From ELFIN Measurements of the Precipitation Ratio
Original language description
Whistler-mode chorus and hiss waves play an important role in Earth's radiation belt electron dynamics. Direct measurements of whistler wave-driven electron precipitation and the resultant pitch angle distribution were previously limited by the insufficient resolution of low Earth orbit satellites. In this study, we use recent measurements from the Electron Losses and Fields INvestigation CubeSats, which provide energy- and pitch angle-resolved electron distributions to statistically evaluate electron scattering properties driven by whistler waves. Our survey indicates that events with increasing precipitating-to-trapped flux ratios (evaluated at 63 keV unless otherwise specified) correlate with increasing trapped flux at energies up to similar to 750 keV. Weak precipitation events (precipitation ratio <0.2) are evenly distributed, while stronger precipitation events tend to be concentrated at L > 5 over midnight-to-noon local times during disturbed geomagnetic conditions. These results are crucial for characterizing the whistler-mode wave driven electron scattering properties and evaluating its impact on the ionosphere.
