    This paper reports measurements collected by satellites near the Earth and another spacecraft placed beyond the magnetosphere to measure the inputs entering the ionosphere-magnetosphere (IM) system. Our goal is to relate the energy inputs observed far from the Earth to the ionospheric measurements gathered by thousands of GPS receivers on the American continent during intense magnetic storms. We have analyzed data corresponding to 12 magnetic storms between 2011 and 2013. The amount of energy deposited in the northern and southern hemispheres was found to control the appearance and asymmetry of neutral and ionized density perturbations that propagate from the poles to the equatorial lines. These perturbations are known as large-scale traveling ionospheric disturbances (LSTID) and can produce significant errors in over-the-horizon radars.

    Keywords: Large scale traveling atmospheric Disturbance, Large Scale Traveling ionospheric disturbance, Poynting flux measurements, IMF Bz component, GOCE neutral density
