Název v původním jazyce

Multi-dimensional Analysis of Whistler-mode Waves in the Radiation Belt Region

Popis výsledku v původním jazyce

Whistler-mode waves in the Earth's inner magnetosphere are believed to transfer energy between different parts of the electron phase space distribution and thus to play a significant role not only in the acceleration of radiation belt electrons to relativistic energies, but also in the losses of electrons from the radiation belts by their precipitation into the high-latitude ionosphere. Accurate description of propagation characteristics and time-frequency structure of whistler-mode waves is therefore important for successful modeling of the dynamics of the Van Allen radiation belts. We describe different techniques for determination of wave modes, propagation directions, and time-frequency structure of electromagnetic waves based on multi-component measurements of the magnetic and electric field fluctuations. We show comprehensive examples of application of these techniques to the analysis of spacecraft observations of whistler-mode chorus. Multi-component data from the Cluster and Van Allen Probes missions are used as an input for the different analysis methods whose results are compared and discussed.
