Linear modeling of ionospheric electrodynamics from the IMF and solar wind data: Application for space weather forecast

It has been demonstrated that large-scale, quasi-steady geomagnetic perturbations at high latitudes are primarily controlled by the interplanetary magnetic field and solar wind parameters. We employ the linear regression model of ionospheric electrodynamics (IZMEM) to predict convection in the northern and southern polar ionospheres on the basis of measured IMF near the Earth's orbit. This model is also capable to provide global patterns of the ionospheric electric fields and currents, magnetic perturbations, field-aligned currents, and Joule heating rate.
