Session ID#: 32177
Session Description:
Geomagnetic storms and substorms have dramatic consequences for the coupled Magnetosphere-Ionosphere-Thermosphere (M-I-T) system that test our system-level understanding. The Sub-Auroral Polarization Stream (SAPS) is one such consequence, understood as a latitudinally narrow band of enhanced poleward-directed (ionosphere) / radially directed (magnetosphere) electric field that has a width of one to several degrees and extends across many hours of magnetic local time towards the evening sector. SAPS are present in regions equatorward of the auroral electron precipitation boundary. We welcome presentations that address ionospheric and thermospheric dynamics resulting from M-I-T coupling with specific focus on the cross-domain connections to magnetospheric drivers. Experimental, theoretical and model-based estimates of the location, extent and intensity of currents, electric fields and composition and density structures are of interest. Interpreted simulation results of the coupled system are sought. We welcome comprehensive analyses of events selected in the CEDAR-GEM SAPS challenge.
