Solar wind ULF wave frequency dependence of the ionospheric response

Using the OpenGGCM global MHD simulations of the magnetosphere-ionosphere system, we study the ionosphere response dependence on the frequency of the ULF waves in the solar wind. This study extends our early study that showed that there is a frequency dependence in a deposited energy distribution at the ionosphere level. In this study we examine the range of frequencies and analyze the ionosphere response dependence in different sectors of the ionosphere. Our goal is to understand at what frequencies the excitation of the field line resonances (FLR) become important and how these results can be quantified. We also conduct event runs to compare how the results of our simulations can be applied.
