Recent results of measurement, data analysis, theory, and simulations confirm that whistler mode waves play
an important role in the dynamical behavior of the Earth's magnetosphere. This especially concerns the outer Van Allen
radiation belts. In spite of these new advances, many questions related to the origin and effects of these waves still
remain open.
We analyze whistler-mode waves using a database of survey measurements of the Waves instruments of the
Electric and Magnetic Field Instrument Suite and Integrated Science (EMFISIS) onboard the Van Allen Probes. We use
multicomponent data to estimate wave polarization and propagation parameters and we especially pay attention to the
variability of wave amplitudes. Usual approach is to calculate average or median values as a function of position or
geomagnetic activity. These values then serve as inputs for modeling. We show the importance of using a more
elaborated statistical description.
