New Chorus Diffusion Coefficients for Radiation Belt Modeling
Meredith, Nigel P.; Wong, Jin-Mann; Horne, Richard B. +2 more
Whistler mode chorus is an important magnetospheric wave emission playing a major role in radiation belt dynamics, where it contributes to both the acceleration and loss of relativistic electrons. In this study we compute bounce and drift averaged chorus diffusion coefficients for 3.0 < L* < 6.0, using the TS04 external magnetic field model,…
Global Environmental Constraints on Magnetic Reconnection at the Magnetopause From In Situ Measurements
Lavraud, B.; Génot, V.; Jeandet, A. +5 more
Progress in locating the X-line on the magnetopause beyond the atypical due south interplanetary magnetic field (IMF) condition is hampered by the fact that the global plasma and field spatial distributions constraining where reconnection could develop on the magnetopause are poorly known. This work presents global maps of the magnetic shear, curr…
The global mapping of electron precipitation and ionospheric conductance from whistler-mode chorus waves
Gillespie, Dillon; Connor, Hyunju Kim; Ma, Qianli +4 more
Auroral precipitation is the second major energy source after solar irradiation that ionizes the Earth's upper atmosphere. Diffuse electron aurora caused by wave-particle interaction in the inner magnetosphere (L < 8) takes over 60% of total auroral energy flux, strongly contributing to the ionospheric conductance and thus to the ionosphere-the…
