The Ionsopheric Source of Magnetospheric Plasma Focus Group: Call For Participation at the 2013 GEM Summer Workshop ---------------------------------------------------------------------- From: Rick Chappell , Bob Schunk and Dan Welling We would like to invite your participation in an area of research that is directed toward creating a unified model that incorporates the outflow of plasma from the ionosphere into the creation and dynamics of the important plasma regions of the magnetosphere. This GEM focus group has as its goal to improve the understanding of the role of the ionospheric outflow source by (1) refining outflow modeling through comparison with measurements, (2) adjusting the outflow modeling to become a compatible input to magnetospheric Geospace Global Circulation Models (GGCM), (3) comparing magnetospheric modeling results with satellite measurements and (4) examining ways in which the dynamic magnetosphere can couple back to influence the original ionospheric outflow. We have planned the following four sessions for the upcoming GEM Snowmass meeting and would like for you to suggest topics that you would like to present in the sessions. Session 1—Observational and Modeling Mysteries—June 19, 10:30am This session will be an opportunity for both modelers and experimentalists to present areas of unanswered questions in their work concerning outflow and its effects. The goal will be to solicit discussion from the GEM Ion Outflow-MMM community regarding approaches to solving the outstanding mysteries and to initiate new collaborative research in these areas. Session 2—The Magnetosphere-Ionosphere System With and Without Outflow-June 19, 1:30pm This session will compare and contrast the characteristics of periods of strong outflow with periods of weak outflow in both the observational and modeling results. A focal point of this session will be to work toward a self-consistent coupling in the merging of the ionosphere and magnetosphere models considering effects such as precipitation, currents and electric fields. Session 3—General Contributions in Measurements, Modeling and Merging— June 19, 3:30pm This session will cover a variety of topics related to measuring and modeling the ionospheric outflow and its effects on the magnetosphere as well as merging the ionospheric and magnetospheric models. Session 4—Planning Session—June 20, 10:30am This will be an open discussion on the status of the focus group accomplishments in order to identify areas of research that are needed and approaches that can be initiated to drive new modeling, measurements and GGCM results. Please send your topics and suggestions to Rick Chappell at rick.chappell@vanderbilt.edu. We look forward to seeing you at the GEM meeting in June. +-------------------------------------------------------------------+ | To subscribe GEM Messengers, send an e-mail to | | | | with the following command in the body of your e-mail message: | | subscribe gem | | To remove yourself from the mailing list, the command is: | | unsubscribe gem | | | | To broadcast a message to the GEM community, please contact | | Peter Chi at | | | | Please use plain text as the format of your submission. | | | | GEM Messenger is also posted online via newsfeed at | | http://heliophysics.blogspot.com and | | http://www.facebook.com/heliophysics | | | | Back issues are available at ftp://igpp.ucla.edu/scratch/gem/ | | | | URL of GEM Home Page: http://aten.igpp.ucla.edu/gemwiki | | Workshop Information: http://www.cpe.vt.edu/gem/index.html | +-------------------------------------------------------------------+
