[Special] Strategic Priorities for Funding in the NSF Antarctic Program (Ports Ballroom IV-V)

NSF has requested that the National Academy of Science develop a consensus recommendation on the most compelling research that can be supported in the coming decade and outline steps forward to implement this research. This meeting is to engage the space science community to participate in the development of this consensus recommendation. The Antarctic can be a platform for measurements and investigation of space weather phenomena and several measurement programs are presently active. How should funding priorities be set for this research during the coming decade? Please help to establish these priorities. Very broad key scientific questions have been identified in the 2011 NRC report “Future Science Opportunities in the Antarctic and Southern Ocean”. The relevant question for our community is “What can the Antarctic platform reveal about the interactions between the Earth and the space environment”. The results from the NAS committee established to develop funding priorities will have an important impact on funding decisions at NSF and our research community needs to be strongly represented.

[GGCM] Metrics and Validation (Ports Ballroom VI-VIII)

Validating Models Under Extreme Geomagnetic Conditions.

Extreme events in the geospace environment are among the most interesting scientifically as well as important for their space weather consequences. The goals for this session are: to show model results for extreme events in the magnetosphere, to share information about the range of conditions where models have been validated, to assess methods for validating model performance with limited observations (such as for early historical events), and to assess the reliability of a model outside the range in which it has been validated. These results will guide our understanding of the magnetosphere under extreme conditions, and provide insight into what physics needs to be incorporated into models so that they perform better during extreme events. Contributions to these and related issues are welcome.
