Abstract
Geospace is a system of systems comprised of interconnected physical domains: the magnetosphere, including all of its regions; the ionosphere; and the upper atmosphere in which the ionosphere is embedded. During geomagnetic storms, all of these domains become active and engage in complex, non-linear, cross-domain interactions that profoundly alter the entire system. Understanding and ultimately predicting these events requires modeling geospace as whole. At the same time, recent work has demonstrated the importance of cross-scale coupling in mediating the complex storm-time interactions, therefore requiring that such holistic models possess both sufficient resolving power and a representation of subgrid physics to capture the relevant processes across a broad range of scales. In this presentation, I will describe recent work on the development of such a high-resolution holistic model of the geospace system, the Multiscale Atmosphere-Geospace Environment (MAGE) model. MAGE is being developed by the Center for Geospace Storms (CGS), one of the three NASA DRIVE Science Centers that was recently selected for Phase II implementation. I will present the scientific objectives of the center, highlight some recent results from the MAGE model, and discuss ways in which the Center can promote synergies with MMS and other missions of the NASA HSO fleet.
