We invite you to submit an abstract to our AGU session titled “SM008: Field-aligned Currents, Poynting Flux, Auroral Precipitation and Their Role in Magnetosphere – Ionosphere – Thermosphere Coupling.”
Session description: During geomagnetic storms, the magnetosphere transmits significant energy and momentum into the upper atmosphere via field-aligned currents, Poynting flux, and auroral precipitation. In response, the ionospheric electric potentials and conductances increase, the thermosphere heats and expands, and the global atmospheric circulation changes. The ionosphere – thermosphere feedback, in turn, can influence magnetospheric dynamics. The heated thermosphere enhances ionospheric outflows. The modified global circulation redistributes plasmas and neutrals, alters the ionospheric conductance and electric field, and thus changes the magnetospheric convection and reconnection. In recent years, advanced physics-based models (e.g. OpenGGCM, LFM, BATSRUS, CTIPe, TIEGCM, and GTIM) and extensive datasets (e.g. AMPERE, SWARM, e-POP, and DMSP) are available to unveil the complex coupling processes of the magnetosphere-ionosphere-thermosphere(MIT) system. Therefore, it is timely to gather these recent research efforts. This session solicits papers on observations, simulations, and theoretical investigations that address magnetospheric energy/momentum inputs and their impact on the coupled MIT system.
