In the previous research (Lyatskaya et al. 2014, 2015, 2016), we used numerical simulation to model and study the effect of the inter-hemispheric field-aligned currents. We considered also the effect of these currents on total magnetosphere-ionospheric current system in two hemispheres, and also computed the maps of the equivalent ionospheric currents in two hemispheres for different seasons and substorm conditions. We continue studying the model outcomes, advancing some important features, developing real life applications, and comparing the simulation results to satellite and ground-based observation data.

August 2012 - July 2014
Developed a numerical model of 3D magnetosphere-ionosphere current system including interhemispheric field-aligned currents flowing between conjugate polar ionospheres; examined effects of the currents on geomagnetic activity, ionosphere, and upper atmosphere in the polar regions in both hemispheres. Developed a course for undergraduate students in scientific computing and numerical analysis of satellite data, taught how to analyze, verify and convert satellite data to scientific units; taught the intro to numerical modeling of space processes.
