Abstract | The duration (τ) and chirping rate (Γ) of whistler mode chorus waves are two of the most important properties to understand chorus generation mechanism and to quantify effects of nonlinear wave particle interactions on radiation belt electron acceleration. In this study, we perform the first statistical analysis of the duration and chirping rate of falling tone chorus elements using Van Allen Probes data. We found that τ increases and Γ decreases with increasing L-shell, although the dependence is weak. The duration from dawnside and dayside have similar distributions, which is a bit longer than those from duskside and nightside. However, Γ has little dependence on MLT. The relation between τ and Γ shows that τ scales with Γ as (Formula presented.), supporting one of the previous theoretical models of rising tone chorus in Teng et al. (2017). Our results should provide important insights to deepen our understanding of falling tone chorus excitation. |
