Electromagnetic Energy Deposition During M I T coupling
Abstract
Electromagnetic energy deposition to the coupled Magnetosphere Ionosphere Thermosphere (M I T) system takes place in the polar cap and its boundary region. In these localities, the Earth’s magnetic field lines are open and connect directly to the interplanetary magnetic field (IMF). This direct connection permits the direct access of solar wind (SW)-M plasma and electromagnetic energy to the underlying coupled I T system and results in a series of geophysical phenomena (e.g. storms-substorms, aurorae, thermospheric mass distribution-heating) adversely impacting low Earth orbiting (LEO) satellites. However, this high latitude M I T system also couples to the auroral and subauroral regions resulting in some interesting responses and feedback mechanisms adversely impacting technology. While thermospheric responses can be studied by employing high resolution CHAMP-GRACE-GOCE accelerometer measurements, their M I drivers can be investigated by Cluster-Polar magnetospheric-plasmaspheric and DMSP topside ionospheric measurements in great details.
