Abstract: We present a high level overview of Earth's immediate space environment, called geospace, and contemporary efforts to model it. As with the modeling of many complex, multi-scale systems one faces the challenges of limited physical understanding of the system and its processes, less-than-ideal numerical procedures, and computer limitations. In spite of these difficulties, advanced modeling of geospace is important, because geospace is the only largescale plasma physical system that is accessible to detailed in situ measurements, and because its variability, “Space Weather”, has a substantial impact on human activities in space and on the ground. As an example of state-of-the-art geospace modeling we discuss the global modeling of magnetotail turbulence.
