Call for Presentations at 2012 GEM Summer Workshop: Ion Outflow Focus Group ---------------------------------------------------------------------- From: Dan Welling The GEM focus group on The Ionospheric Source of Magnetospheric Plasma - Measuring, Modeling and Merging Into the GEM GGCM will hold four sessions at the upcoming meeting in Snowmass. The conveners, Rick Chappell, Bob Schunk and Dan Welling would like to invite participation from the GEM community for any of the following four sessions. The sessions will begin with a summary overview talk and will be followed by contributed workshop-style talks with discussion.. The topics and times of the sessions are listed below. Please contact the session chairman for each of the four sessions to be added to the agenda for the session. We look forward to your participation in these sessions. June 20, 2012; 3:30-5:00pm - Measurements of Ion Outflow in the Ionosphere and Magnetosphere. The Earth's ionosphere has been shown to be a significant contributor of plasma to different particle populations of the magnetosphere. Through a variety of energization processes, the low energy ionospheric particles are transported from low altitudes upward into the magnetosphere where they can become more energized and can help create fundamentally important regions such as the plasma sheet and ring current. This workshop will review and discuss observations of outflow in the ionosphere and magnetosphere as a stimulus for refining existing outflow models. Session Chairman: Rick Chappell (rick.chappell at vanderbilt.edu) June 21, 2012; 8:15-10:00am - Modeling Ionospheric Outflow There is a continuous ion outflow from the Earth at high latitudes. The outflow consists of light thermal ions (H+ , He+ and O+) and energized ions (NO+, O2+, N2+, O+, N+, He+ and H+). The ion energization in the polar wind is associated with photoelectrons, hot magnetosphere electrons and ions, wave-particle interactions in the cusp and nocturnal oval at various altitudes, electromagnetic wave turbulence above the polar cap, and centrifugal acceleration. In addition, the ion outflow occurs in conjunction with magnetospheric convection, which causes the high-latitude plasma to drift into and out of the dayside ionosphere, cusp, polar cap, nocturnal auroral oval, and subauroral night-side ionosphere. Because of the complicated dynamics, various ion outflow models have been developed, including hydrodynamic (fluid), hydromagnetic, semi-kinetic, kinetic, generalized transport, and macroscopic particle-in-cell models. This workshop will identify the ionospheric outflow models that currently exist, establish the strengths and limitations of existing models, and determine the important outflow processes that need to be included in outflow models. Session Chairman: Bob Schunk (schunk at cc.usu.edu) June 21, 2012; 1:30-3:00pm - Merging Outflow and GGCM Models Geospace Generalized Circulation Models (GGCMs), invaluable tools for studying the Earth's magnetosphere, have historically neglected the ionospheric source of magnetospheric plasma. Recently, an increased recognition of the importance of this source has spurred the magnetospheric modeling community towards finding new, innovative ways to include it in the large-scale models. This workshop will examine existing merging techniques between outflow and magnetosphere models and review recent discoveries concerning the impact ionospheric outflow has on the global magnetospheric results. Session Chairman: Dan Welling (dwelling at umich.edu) June 21, 2012; 3:30-5:00pm - Outflow MMM Discussion and Planning The Ionospheric Source of Magnetospheric Plasma: Modeling, Measuring, and Merging into the GEM GGCM focus group (or simply Outflow MMM) is a focus group aimed at combining research of ionospheric outflow with Geospace General Circulation Models (GGCMs). The focus group has four major goals: refine existing outflow models through data-model comparisons, merge these models into the GGCMs and examine the impact on the magnetosphere, evaluate the coupled codes through data-model comparisons, and examine feedback from the magnetosphere to the ionospheric outflow. This session will summarize the Outflow MMM sessions that have taken place throughout the workshop and work with the GEM community to plan for the future of the 5-year focus group. Session Chairmen: Rick Chappell (rick.chappell at vanderbilt.edu) Bob Schunk (schunk at cc.usu.edu) Dan Welling (dwelling at umich.edu) We look forward to your participation in these joint sessions. ---------------------------------------------------------------------- 4. Call for Presentations at 2012 GEM Summer Workshop: Dayside FAC and Energy Deposition Focus Group ---------------------------------------------------------------------- From: Jimmy Raeder and Delores Knipp We would like to invite contributions to the Dayside FAC and Energy Deposition (FED) focus group at the upcoming GEM meeting in Snowmass. This will be the second year in which special sessions on this topic have been held. The effort focuses on explaining the relation between enhanced dayside Poynting flux and field-aligned currents, sources of field-aligned currents in the solar wind and magnetosphere and their impacts in the ionosphere-thermosphere system. The Focus Group goals and other information are at: http://aten.igpp.ucla.edu/gemwiki/index.php/FG:_Dayside_FACs_and_Energy_Deposition The FED focus group will hold a session on Thursday morning beginning at 10:30. The session will cover data, theory, and modeling aspects of the following topics: * Dayside Poynting Flux, Joule Heating and Their Relation to Field Aligned Currents * Particle Energy Deposition on the Dayside * Dissipation of Magnetospheric Energy in the Dayside Thermosphere * Thermospheric Density Enhancements and Traveling Atmo/Ionospheric * Disturbances Solar Wind Drivers for Extreme Dayside Poynting Flux Events Each speaker will be allotted time for 5 slides, in order to ensure enough time for discussion. At least one of the slides should deal with unresolved issues. If you have not already done so, please send the title(s) and session(s) of your contribution(s) to us at your earliest convenience at the email addresses listed above. Jimmy Raeder (J.Raeder at unh.edu) Delores Knipp (delores.knipp at gmail.com) ---------------------------------------------------------------------- 5. Call for Presentations at 2012 GEM Summer Workshop: Tail-Inner Magnetosphere Interactions Focus Group ---------------------------------------------------------------------- From: Pontus C. Brandt John Lyon Frank Toffoletto This is a call for contributions for the new GEM focus group FG on Tail-inner magnetosphere interactions. Part of this FG's goal is the understanding the transport and acceleration of plasma from the tail to the inner magnetosphere. An executive summary of the new focus group, can be found on the GEM wiki website (http://aten.igpp.ucla.edu/gemwiki/index.php/Main_Page). We are asking that you keep your presentation to no more than 5 minutes (~3 slides), so as to allow plenty of time for discussion. Of note, there will be 2 tutorials related to this FG, the first will be by Harry Warren: Tutorial on SADs and comparative solar/geospace system on Monday and the second by Dick Wolf on the tail on Thursday. Breakouts are scheduled for Wednesday morning and all-day Thursday. If you are interested in making a presentation, please email us with a title. We look forward to seeing you at GEM.
