A new diffusion matrix for whistler mode chorus waves
Meredith, Nigel P.; Horne, Richard B.; Glauert, Sarah A. +5 more
Global models of the Van Allen radiation belts usually include resonant wave-particle interactions as a diffusion process, but there is a large uncertainty over the diffusion rates. Here we present a new diffusion matrix for whistler mode chorus waves that can be used in such models. Data from seven satellites are used to construct 3536 power spec…
Magnetic topologies of an in vivo FTE observed by Double Star/TC-1 at Earth's magnetopause
Dunlop, M.; Raeder, J.; Zhong, J. +5 more
transfer events (FTEs) are magnetic flux ropes formed at planetary magnetopauses (MPs). Although evidence suggests that FTEs form through time-dependent magnetic reconnection, details of that process and 3D structure of the flux ropes remain largely unclear. This letter presents Double Star/TC-1 data of an FTE occurred on 7 April 2004 which show t…
Multiscale studies of the three-dimensional dayside X-line
Hasegawa, H.; Fuselier, S. A.; Burch, J. L. +4 more
We review recent experience from the Cluster, Double Star, and THEMIS missions for lessons that apply to the upcoming Magnetospheric Multiscale Mission (MMS) being developed for launch in 2014. On global scales, simulation and statistical studies lead to mean configurations of dayside reconnection, implying specific relative alignments of the infl…
Generation of Pi2 pulsations by intermittent earthward propagating dipolarization fronts: An MHD case study
El-Alaoui, M.; Walker, R. J.; Goldstein, M. L. +3 more
Using a global magnetohydrodynamic (MHD) simulation of the magnetosphere during a disturbed interval on 14 September 2004, we have investigated fluctuations in plasma properties of the magnetotail in the Pi2 range and their relationship to dipolarization fronts (DFs). Results from the MHD simulation indicate that this event is a very active interv…
