Vertical variations in the N_2 mass mixing ratio during a thermospheric storm that have been simulated using a coupled magnetosphere-ionosphere-thermosphere model

摘要

The Center for Integrated Space Weather Modeling's (CISM) suite of models was run together to simulate the passage of an idealized coronal mass ejection (CME) from the Sun's corona to geospace. The resulting interplanetary magnetic field (IMF) pattern included a period during which B_z was southward. The effects of this CME were then propagated through the Lyon-Fedder-Mobarry (LFM) model of the magnetosphere to study its influence on the Earth's ionosphere and thermosphere. The effect of these changes on the thermosphere ionosphere nested grid (TING) model was to drive a large ionospheric and thermospheric storm.
