This meeting is being held as part of an outreach effort by the
 +
National Academy of Science, Committee to form a Strategic Vision of
 +
NSF Investments in Antarctic Research.  Antarctica is an important
 +
platform for some areas of Space Weather related research. Our purpose
 +
is to engage the Space Physics community to determine the most
 +
important research questions that are ripe for major advances in
 +
understanding that require or utilize Antarctic infrastructure that
 +
could feasibly be achieved in the coming decade.  The reason for this
 +
is NSF Polar Programs has asked for guidance in setting priority for
 +
funding Antarctic Research due to constrained budgets.  We are
 +
specifically also looking to determine technological, infrastructure
 +
or data sharing developments that can enable the proposed high
 +
priority research, opportunities in international cooperation that
 +
might help advance high priority research or other innovative
 +
arrangements. Please come to offer your ideas and join a lively
 +
discussion about research directions and priorities.

We will present a variety of data analysis scenarios, focused mostly on THEMIS data, but touching on some of the other multi-mission capabilities. The formal presentation will be followed by an open Q&A, help session, and installation clinic.

'''Model Uncertainty: Dealing with uncertain physical processes and boundary conditions'''
 +
 +
In this session we solicit contributions discussing how model uncertainties and uncertain boundary conditions affect model results and validation.  Specifically solicited are strategies to accommodate uncertainty in modeled physical processes (e.g. uncertain radiation belt diffusion coefficients), uncertainty in boundary conditions (e.g. upstream solar wind), or the validation of models at their boundaries (such as ground-based magnetometers).
 +
 +
We will introduce a challenge based on previously run magnetopause standoff simulations that compared model results to magnetopause crossings of geo-synchronous satellites. The few crossings observed during strong events revealed significant discrepancies between the major magnetospheric MHD models. We plan to revisit the challenge on the basis of selected events with steady and changing solar wind conditions and observations near the nose of the magnetosphere. The role of boundary conditions applied at the inner boundary (e.g., ionospheric conductance and convection, plasma density and temperature, magnetic field) can be tested. Some of the questions that can be addressed are:
 +
 +
* Which model is better suited to predict magnetopause position near the nose of the magnetosphere under typical conditions/storm time conditions?
 +
* What model assumptions affect the model predictions significantly and lead to differences between models?
 +
* How does the magnetopause change during extreme events
 +
* How sensitive is model performance to changes of the boundary conditions?
 +
* Can we define common settings for the inner boundary location, and the plasma density or temperature applied at this boundary?
 +
 +
We also anticipate presentations on topics such as the influence of the plasma sheet boundary conditions on ring current development and also welcome specifications of uncertainties derived from observations and lessons from data assimilation and ensemble modeling methods.

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.

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

This meeting is being held as part of an outreach effort by the National Academy of Science, Committee to form a Strategic Vision of NSF Investments in Antarctic Research. Antarctica is an important platform for some areas of Space Weather related research. Our purpose is to engage the Space Physics community to determine the most important research questions that are ripe for major advances in understanding that require or utilize Antarctic infrastructure that could feasibly be achieved in the coming decade. The reason for this is NSF Polar Programs has asked for guidance in setting priority for funding Antarctic Research due to constrained budgets. We are specifically also looking to determine technological, infrastructure or data sharing developments that can enable the proposed high priority research, opportunities in international cooperation that might help advance high priority research or other innovative arrangements. Please come to offer your ideas and join a lively discussion about research directions and priorities.

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

Model Uncertainty: Dealing with uncertain physical processes and boundary conditions

In this session we solicit contributions discussing how model uncertainties and uncertain boundary conditions affect model results and validation. Specifically solicited are strategies to accommodate uncertainty in modeled physical processes (e.g. uncertain radiation belt diffusion coefficients), uncertainty in boundary conditions (e.g. upstream solar wind), or the validation of models at their boundaries (such as ground-based magnetometers).

We will introduce a challenge based on previously run magnetopause standoff simulations that compared model results to magnetopause crossings of geo-synchronous satellites. The few crossings observed during strong events revealed significant discrepancies between the major magnetospheric MHD models. We plan to revisit the challenge on the basis of selected events with steady and changing solar wind conditions and observations near the nose of the magnetosphere. The role of boundary conditions applied at the inner boundary (e.g., ionospheric conductance and convection, plasma density and temperature, magnetic field) can be tested. Some of the questions that can be addressed are:

  • Which model is better suited to predict magnetopause position near the nose of the magnetosphere under typical conditions/storm time conditions?
  • What model assumptions affect the model predictions significantly and lead to differences between models?
  • How does the magnetopause change during extreme events
  • How sensitive is model performance to changes of the boundary conditions?
  • Can we define common settings for the inner boundary location, and the plasma density or temperature applied at this boundary?

We also anticipate presentations on topics such as the influence of the plasma sheet boundary conditions on ring current development and also welcome specifications of uncertainties derived from observations and lessons from data assimilation and ensemble modeling methods.

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.
