Journal ArticleDOI
Solar wind driving of magnetospheric ULF waves: Pulsations driven by velocity shear at the magnetopause
TL;DR: In this paper, global, three-dimensional magnetohydrodynamic (MHD) simulations of the solar wind/magnetosphere interaction are used to study ultra low frequency (ULF) pulsations in the Earth's magnetosphere driven by shear instabilities at the flanks of the magnetopause.
Journal ArticleDOI
Radial diffusion and MHD particle simulations of relativistic electron transport by ULF waves in the september 1998 storm
TL;DR: In this article, a radial diffusion equation with ULF wave diffusion coefficients and a time-dependent outer boundary condition is solved, and the results are compared with the phase space density of the MHD particle simulation.
Journal ArticleDOI
Community-wide validation of geospace model ground magnetic field perturbation predictions to support model transition to operations
Antti Pulkkinen,Antti Pulkkinen,Lutz Rastätter,Masha Kuznetsova,Howard J. Singer,Christopher C. Balch,Daniel R. Weimer,Gabor Toth,Aaron J. Ridley,Tamas I. Gombosi,Michael Wiltberger,Joachim Raeder,Robert S. Weigel +12 more
TL;DR: This work focuses on studying the models' capability to reproduce observed ground magnetic field fluctuations, which are closely related to geomagnetically induced current phenomenon and supports NOAA SWPC in their selection of the next numerical model that will be transitioned into operations.
Journal ArticleDOI
Initial results from the coupled magnetosphere ionosphere thermosphere model: magnetospheric and ionospheric responses
Michael Wiltberger,Wenbin Wang,Alan G. Burns,Stanley C. Solomon,John G. Lyon,Charles C. Goodrich +5 more
TL;DR: The Coupled Magnetosphere Ionosphere Thermosphere (CMIT) model as discussed by the authors combines the Lyon-Fedder-Mobarry global magnetohydrodynamic (MHD) magnetospheric (LFM) model with the thermodynamic energy equations for the global thermosphere and ionosphere.
Journal ArticleDOI
Observations and simulations of the ionospheric and thermospheric response to the December 2006 geomagnetic storm : Initial phase
Jiuhou Lei,Wenbin Wang,Alan G. Burns,Stanley C. Solomon,Arthur D. Richmond,Michael Wiltberger,Larisa Petrovna Goncharenko,Anthea J. Coster,Bodo W. Reinisch +8 more
TL;DR: In this paper, a Coupled Magnetosphere Ionosphere Thermosphere (CMIT) 20 model was used to simulate the ionospheric response to the 14-15 December 2006 geomagnetic storm.
