DESCRIPTION:"Unraveling Geospace Storms with the MAGE Model: From Global Dy
 namics to Auroral Structures"\n\n \n\nPresented by Dr. Michael Wiltberger\
 , Deputy Director of the High Altitude Observatory\n\n \n\nGeomagnetic sto
 rms—also known as geospace storms—are among the most dynamic and multi
 faceted phenomena in near-Earth space. They are driven by solar wind distu
 rbances and unfold as a complex\, nonlinear interaction of plasmas and fie
 lds across a vast range of temporal and spatial scales. Understanding and 
 modeling these interactions is essential to predicting space weather impac
 ts on modern technology\, from satellites to power grids.\n\n \n\nIn this 
 seminar\, I will introduce the work of the Center for Geospace Storms (CGS
 )\, one of NASA's DRIVE Science Centers\, which is focused on advancing ou
 r understanding of storm-time geospace dynamics. Our central tool is the M
 ultiscale Atmosphere-Geospace Environment (MAGE) model—a next-generation
 \, fully coupled model system that simulates the magnetosphere\, ionospher
 e\, and thermosphere in a unified framework. MAGE is designed to address t
 hree major challenges in space weather modeling: (1) describing the global
  geospace system holistically\, (2) resolving critical mesoscale processes
  such as plasma instabilities and localized currents\, and (3) enabling tw
 o-way coupling with the lower atmosphere to investigate vertical coupling 
 pathways.\n\n \n\nI will present highlights from recent MAGE simulations o
 f the May 10\, 2024 'Gannon' Superstorm—a major space weather event that
  provided a rigorous test for the model. These results showcase MAGE’s a
 bility to reproduce large-scale storm-time dynamics as well as detailed su
 b-auroral and auroral features. Special attention will be given to the gen
 eration of giant auroral undulations\, the role of inner-magnetospheric in
 stabilities\, and the emergence of sub-auroral optical emissions associate
 d with high-energy particle injections. These phenomena not only offer vis
 ual evidence of geospace dynamics but also point to important physical pro
 cesses shaping storm-time energy deposition.\n\n \n\nFinally\, I will disc
 uss how the broader research community can access and engage with MAGE. Th
 is includes availability through NASA’s Community Coordinated Modeling C
 enter (CCMC) Runs on Request service\, the upcoming open-source release of
  the model\, and accompanying open-source Python tools for data analysis a
 nd visualization. Whether your interest lies in plasma physics\, atmospher
 ic coupling\, computational modeling\, or observational validation\, MAGE 
 offers a flexible and extensible framework for exploring the coupled Sun-E
 arth system.
