Comparison of photometer and global MHD determination of the open‐closed field line boundaryournal of Geophysical Research: Space Physics, 109(A1), [ppDownload
We compare open-closed field line boundary positions from the BATS-R-US Global MHD model and CANOPUS photometer measurements of red-line emissions. We choose intervals of steady interplanetary and ionospheric conditions in order to adhere to the \"steady-state'' picture that we are trying to...
Magnetospheric field‐line resonances: Ground‐based observations and modelingournal of Geophysical Research: Space Physics, 110(A10), [ppDownload
We present theory and ground-based observations of field-line resonances (FLRs) excited in Earth's magnetosphere. Three FLR observations are reported, which correspond to large-scale standing shear Alfven wave (SAW) oscillations on nightside field lines extending from premidnight to close to...
Open‐closed field line boundary position: A parametric study using an MHD modelournal of Geophysical Research: Space Physics, 109(A5), [ppDownload
In this paper we investigate the effect of changes in the interplanetary magnetic field ( IMF), solar wind dynamic pressure, and dipole tilt angle on the position of the ionospheric projection of the open-closed field line boundary (OCB) in a magnetohydrodynamic (MHD) model. We carry out a large...
Self‐consistent electron acceleration due to inertial Alfvén wave pulsesournal of Geophysical Research: Space Physics, 110(A10), [ppDownload
We present self-consistent kinetic simulations of the electron response to finite duration shear Alfven wave pulses in a magnetized plasma. In Earth's magnetosphere, the evidence suggests that parallel electric fields in inertial scale shear Alfven waves can accelerate electrons in the...
