Agenda for joint GEM/CEDAR workshop on Saturday, June 22
--------------------------------------------------------

Dear GEM community,

   Please find attached the text describing the joint CEDAR/GEM workshop on
the Saturday bridging the regular CEDAR and GEM meetings.  This workshop
has been described previously in general terms and is fleshed out in much
more detail below.  As the meeting will be held in Boulder directly
following the CEDAR meeting, the information regarding housing and meeting
location can be found at the CEDAR WWW pages.  An especially helpful link
is:

where you can inspect "meeting plans", "daily agenda", "workshops", and
"lodging and transportation" links relevant to the joint meeting.

Best regards,  --- Harlan E. Spence

CEDAR-GEM Workshop on the National Space Weather Initiative (NSWI)


Submitted by:           J. Hughes (GEM Steering Committee Chair)
                        M. Mendillo (CEDAR Steering Committe Chair)
                        H. Spence (GEM Meetings Coordinator)


        As part of this June's CEDAR and GEM activities, a joint workshop
on Space Weather will be held. For the National Space Weather Initiative to
succeed within CEDAR and GEM, it must focus on science driven activities.
The workshop will address how NSF's contributions are unique and important.
To help achieve this, the workshop will have a balance between data/event
driven activities and the discussion of crucial science issues in the
field.  Theoretical uncertainties, modeling dilemmas, and
instrumentation/observational needs will be discussed.
        The plan decided upon was to bridge the CEDAR and GEM meetings
using a three-part, two-site format.  The all-day Saturday session is the
prime day for joint activity.  The limited Friday items are intended
primarily for GEM outreach to CEDAR and likewise, those on Wednesday are
for CEDAR outreach to GEM.


I.   Friday (21 June 1996) - Final Day of CEDAR Workshop (Boulder).
The "normal tutorial" for this day will be on a topic representative of the
magnetospheric physics community's approach to Space Weather. A  summary
will be given of how a state-of-the-art model uses solar/solar wind input
to produce magnetospheric and ionospheric effects for a "generic event." A
presentation on the RICE Convection Model will be given by R. Wolf.



II. Saturday (22 June 1996) - The joint CEDAR-GEM Workshop on NSWI will be
held in Boulder on the CU campus.

MORNING SESSION

                Speakers: G. Siscoe, R. Schunk

9:40 - 10:10    Case Study Activities: synthesis and discussion of focused
science issues that have emerged from activities to date on 11/93  period.
                Speakers: D. Knipp, M. Buonsanto

10:00 - 10:30   BREAK

10:30 - 12:00   New Frontiers: Magnetosphere/Ionosphere/Thermosphere Coupling
                Tentative Speakers:  T. Killeen, C. Russell

LUNCH BREAK

needed to solve them?  C. Russell/T. Killeen, Moderators (Tentative)

        Panel Members (Tentative):  P. Reiff, A. Rodger, H. Singer, J.
Forbes,                                    Sa. Basu, M. Kelley

             Panel:     Brief  initial presentation by each panelist
commenting on the morning presentations
       Audience:        General discussion

4:30 - 5:00             Summing Up - J. Hughes and M. Mendillo



III. Wednesday (26 June 1996) Middle Day of GEM Workshop (Snowmass)
This is the companion to Friday, an opportunity for GEM participants to
learn about the ionospheric physics community's approach to Space Weather
through invitied tutorials. The topics to be covered are non-solar wind
induced perturbations in the ionosphere, and classic, state-of-the-art
modeling of ionospheric storms driven by solar wind/magnetospheric
processes.

1)  Equatorial Spread-F:  Semi-predictable disruptions of the low latitude
ionosphere with severe effects on radio propagation;  observational and
modeling approaches.
        Speaker: M. Mendillo

2)      First-Principle Models of Ionospheric Disturbances:  A status
report on thermospheric and ionospheric storm-time effects capable of being
modeled from solar and magnetospheric input parameters.
                Speaker:  A. Richmond
