Magnetospheric Modeling: State of the Art, Gaps, and Future Innovations
Session ID#: 83439
Session Description:
The holy grail of computational magnetospheric modeling is to resolve the microscopic/kinetic physics while capturing the macroscopic/large-scale behavior of the system. This is a formidable challenge, since it requires resolving physical phenomena occurring over spatial and temporal scales separated by several orders of magnitude. Thus, despite remarkable recent progress, a fully-kinetic model of the Earth’s magnetosphere remains elusive.
This session aims to bring together experts in different disciplines to assess the state of magnetospheric modeling, its limitations and the new ideas/innovations necessary to move forward.
Solicited contributions include:
1) Modeling studies: from global-MHD to local models, including those treating only specific components of the environment and its couplings (ionosphere, plasmasphere, ring current, radiation belts, waves, …), empirical models, etc.
2) Studies combining modeling and observations (including verification and validation) to expose successes and limitations of current models.
3) Numerical, data-science, high-performance-computing and information-science-and-technology techniques deemed critical to advance the field.
