Geospace System

2009-08-14T15:04:51Z

Wiltbemj: /* '''Geospace System''' */

Geospace System is a potential new focus group for the GEM community. In this space we can developed the focus group proposal which will be considered by the Steering Community as part of its process in selecting new focus groups.

As a starting point here is the initial announcement from the GEM messenger describing the discussion session held at the 2009 GEM Meeting.

== Prospectus for a GEM Focus Group on the "Geospace System" ==

Session Organizers Bill Lotko and George Siscoe

We would like to initiate a discussion among the magnetospheric and aeronomy
communities (portions, at least) on the prospect of undertaking a global,
system-dynamics study of the coupled solar
wind-magnetosphere-ionosphere-thermosphere system, which we identify simply
as the geospace system. The suggestion responds to two circumstances:
first, 50 years of magnetospheric research have shown the geospace system to
be interactively coupled in multiple ways from the solar wind to the
thermosphere, and second, as GEM moves in its long-range program from the
'divide-and-conquer' stage to the more challenging synthesis stage, a focus
group devoted to problems of the coupled system will leverage scientific
progress in each GEM research area. The magnitude of the task to comprehend
the global system in its coupled complexity is almost certainly too great
for a single, scientist-centered research team and probably too great for
the multiple teams of a single institution. Instead it would seem to require
a sustained collaborative effort by experts of manifold specialties
distributed among many institutions. It might even take the combined
collaboration of the GEM community and a sizable portion of the CEDAR
community.

The priorities of such a focus group clearly must be enlightened by
community interest. To begin the conversation we can suggest among many
possible directions several problems, each global in scope and of
considerable current interest . We have asked some GEM participants to help
initiate the discussion with a few slides on each problem. They include: 1)
the dayside reconnection potential, its relationship to the polar cap
potential, and the saturation of both at large IMF; 2) global resonance,
periodicity of the magnetospheric response, and sawtooth phenomena; 3)
ionospheric-magnetospheric plasma circulation, including ionospheric
outflows, and its effects on plasmasheet and inner magnetospheric dynamics;
and 4) prompt penetration electric fields and their relationship to the
dayside ionospheric superfountain, storm enhanced density, and plasmaspheric
plumes. While some aspects of these global problems can be treated as
regional phenomena, differentiated by distinct physical processes, their
dynamics seem to evolve as an integrated whole during extreme solar wind
conditions. The geospace system thus behaves coherently across a broad
spatiotemporal range, making it difficult to unravel its causal behavior by
considering the response in terms of isolated elements or processes.
Integration of global problems of this type into a system-dynamics picture
spans the expertise of all five GEM research areas and several CEDAR working
groups. We invite participation from the GEM community in deciding whether
the time is right for this focus group, and, if so, how best to structure
its direction.
