From: Phil Erickson <pje at haystack.mit.edu>.
Call for Participation:
*Session I: (Mon 27 Jun, 4 - 6 pm)
*Session II: (Tue 28 Jun, 10 - 12 am)
*Session III: "M-I Coupling within Plasmasphere Boundary Layer"
JOINT WITH CEDAR. (Tue 28 Jun, 1:30-3:30p)

Phil Erickson <pje at haystack.mit.edu>
GENERAL CALL:
The GEM PMI focus group would like to invite presentation and participation in
three sessions at this year's GEM/CEDAR joint workshop. The three sessions take
place on Monday and Tuesday, as listed above. Session III is devoted especially
to joint GEM/CEDAR topics. We also invite active participation and
presentations of new results by members of the LSW FST on the Plasmasphere.
Please e-mail us for a speaking slot as soon as possible.
SCIENCE TOPICS:
1) Modeling plasmaspheric density: formation, evolution, morphology.
Observations in support of models, and model-data comparisons. What are the
radial, MLT, and field-aligned structures? What evidence is there for
interhemispheric asymmetries?
2) The inner magnetospheric electric field: global modeling, observations, and
impact.
3) Plasmaspheric plume density distribution. How well do plasmaspheric drainage
plumes map to ionospheric SED plumes moving westward? What is the altitude and
temporal signature as we move from low to mid to high latitudes? What creates
the "lumpy" structure within plumes, and how does this structure evolve? Is the
plasma inside late-storm plumes from the magnetosphere, or outflow from a
hot-ionosphere high-latitude source? Where are the gaps in understanding?
4) PBL electric field variability. What is the altitude dependence of the
variability and what implications does this have for field-aligned currents and
the scaling of the magnetic field mapping function / electric field structuring?
Do we have enough empirical evidence to make a statement and can data-guided
models help?
5) Plasmapause location and structure. How do ionospheric and magnetospheric
people locate the plasmapause / PBL? Are these compatible? What forms the
structure seen on the PBL inner edge?
6) Wave/particle interactions and macroscale instabilities in the PBL. Where
are these located (in plasmasphere, in ducts, on plasmapause, within plume, ..)?
Where do they have an impact on particle trajectories through scattering or
anomalous heating?
7) Conductivity control of PBL electrodynamics. How is the coupled electric
field on PBL field lines affected by ionospheric conductivity in either or both
hemispheres?

Invitation to Participate:Please come and participate in a multi-disciplinary
discussion of the response of geospace and
the atmosphere to high speed streams, both in general and as observed during the
recent unusual
solar minimum. All are welcome!
* Speakers (listed below) have been invited to introduce new findings, the
questions they raise, and possible consequences in other geospace regions.
* We are very interested in information about additional features in geospace
during high-speed streams. Please let the conveners know if you have 1-2 slides
to present that raise new issues.
* We are hoping to take advantage of the unique environment that the joint
CEDAR-GEM meeting provides to identify the signatures of related processes in
different regions.
Please come and add your expertise to the mix in the joint workshop. Workshop
Description:This workshop addresses the impacts of high speed streams on the
development of auroral activity,
radiation belt enhancements, inner magnetosphere-subauroral response, and
atmospheric
perturbations. A particular sub-focus is to explore the changes in the
geospace-atmosphere
response in the recent unusual solar minimum interval due to the combination of
strong and
long-lasting high speed streams, the lowest average IMF and solar wind densities
ever recorded
at 1 AU, and the lowest solar EUV fluxes in three solar cycles, placing system
responses into a
backdrop of tenuous ionospheric densities and low conductivities.

We would like to invite presentations and participation in this session at the
GEM-CEDAR joint workshop. The session description and a list of science
questions are given below. The format of the presentations is informal with
several slides and we would like to encourage science discussions.
If you are interested to give a talk in the session, please let us know.
<b>Session Description:</b>
In the last decade, there have been many new development in understanding the
electrodynamic coupling of the inner magnetosphere with the middle and low
latitude I-T system. One of the great achievements was the identification and
explanation of common magnetic-storm processes in plasmaspheric and ionospheric
data and images, and the realization that disturbance dynamo and prompt
penetration electric fields are not independent but interact with each other
non-linearly. New developments continue to highlight the coupled nature of the
system during quiet times as well as in response to magnetic storms. Significant
gaps in our understanding still exist and lie in the need to quantify the
various sources of electrodynamic variability at mid and low latitudes and the
interactions and feedback between them. For instance, during quiet times,
fluctuating winds in the thermosphere from sources in the lower atmosphere are
likely to compete with fluctuation of magnetospheric sources, both in terms of
driving winds and in imposing modest penetration electric fields. These sources
of quiet-time fluctuations in the fields, render it extremely difficult to
separate storm from quiet, since the background from one day to the next can be
50% of the signal. During storms the magnetospheric sources tends to dominate
but lack of knowledge in the uncertainty in the quiet background can confuse
interpretation of the storm response. This workshop is designed to bring
together the CEDAR and GEM experts in the sources of mid and low latitude
electrodynamics from the inner magnetosphere, thermospheric wind dynamo, and
forcing from the lower atmosphere.
New science questions to lead discussions:
1) Response of low and mid-latitude ionosphere to penetrating magnetospheric
fields vs. disturbance dynamo.
During a storm, the effects of both penetrating magnetospheric fields and
disturbance dynamo fields drive changes in the ionosphere. What's typical,
what's not? Does the F-layer go up or down, at what local times and for how long
after storm onset? During disturbances, can the effects be reasonably separated
or predicted? Do the responses depend on solar flux conditions?
2) Contribution of magnetospheric sources to quiet-time variability at low and
mid latitudes.
During periods of low geomagnetic activity, the ionosphere continues to exhibit
large variability. Is this due only to sources such as tropospheric forcing, or
is the ionosphere more susceptible to forcing from magnetospheric sources, owing
to the low ionospheric/magnetospheric densities of recent solar minimum conditions?
3) Storm-time wind dynamo electric fields in the inner magnetosphere.
The thermospheric winds that develop during geomagnetic storms drive electric
fields that have a profound effect on the ionosphere. This disturbance dynamo
develops after storm onset and persists for many hours after storm drivers
lessen. These storm-time fields develop on magnetic L-shells that are usually
occupied by cold plasma, but stripped of that during storms. What do the storm
time dynamo electric fields look like from the point of view of the inner
magnetosphere? Are these important for post-storm plasmaspheric dynamics?
