Abstract

The Coupled Thermosphere Ionosphere Plasmasphere electrodynamics (CTIPe) model is a global physics-based model that will be used to explore the ionosphere-thermosphere system response to the onset of 2015 St. Patrick day storm. This storm, which was one of the strongest geomagnetic storms of the solar cycle 24, was generated by a magnetic cloud followed by a coronal mass ejection (CME) impact. The ionospheric disturbances are identified to be caused by superposition of many effects, like prompt penetration electric fields, neutral winds, thermal expansion and composition changes. Over Europe, measurements like ionosonde observations and Total Electron Content (TEC) maps derived from Global Navigation Satellite System (GNSS) indicate four storm phases (compression, the start of the main phase, partial recovery and second substorm) during 17th March 2015. CTIPe reproduces well the positive ionospheric storm phases, the compression of the ionosphere to a thin shell and the surges excited in the Auroral region. Furthermore, it reproduces well the changes in the neutral mass density measured by the SWARM satellites. Finally, CTIPe exhibits a coherent storm response for the thermospheric winds, temperature, composition and electron densities during the storm. These model results will be used to support the interpretation of the storms driving mechanisms.
