*************************** ** THE GEM MESSENGER ** *************************** Volume 12, Number 10 May 16, 2002 ------------------------------------------------------------------------ Descriptions for the Inner Magnetosphere/Storms Campaign Working Group 1 Sessions on Ring Current and Plasmasphere at 2002 GEM Telluride Workshop ------------------------------------------------------------------------ From: Mike Liemohn (liemohn at umich.edu) Dennis Gallagher (Dennis.Gallagher at msfc.nasa.gov) Please find below descriptions for the Working Group 1 (Ring Current and Plasmasphere) sessions of the Inner Magnetosphere/Storms Campaign at this summer's GEM Workshop. We are currently soliciting presentations for any of these sessions and for the Tuesday night poster session (which includes these topics as well as presentations on all other IM/S-related issues). Requests for oral presentations should be sent directly to the session chairs, while requests for poster presentations should be submitted at the Workshop website: http://koala.rice.edu/~gem/gem2002/gem2002.html Please note the housing deadlines (May 17 for 2 hotels, June 1 for the other) and other important dates. We will try our best to accommodate everyone in their preferred session, but please keep in mind that some shifting may be necessary. Inner Magnetospheric Magnetic and Electric Fields (joint WG1/WG2) Chairs: Anthony Chan (anthony-chan at rice.edu) Mike Liemohn (liemohn at umich.edu) Time: Monday, 10:40 am to 12:10 pm Recently, there have been numerous advances in understanding the perturbed state of the inner magnetospheric magnetic and electric fields during storms. In this session, speakers will present results from a variety of techniques demonstrating the progress made thus far and highlighting the progress yet to be made. The session will primarily focus on magnetic field structure and dynamics, while most of the electric field discussion will be reserved for the afternoon session. Near-Earth Electric Fields Chairs: Jerry Goldstein (jerru at rice.edu) Mike Liemohn (liemohn at umich.edu) Time: Monday, 1:30 to 3:00 pm Electric fields develop over large and small scales throughout the inner magnetosphere. The objective of this session is to explore their sources, properties, and effects. Empirically Determined Plasmaspheric Structures Chairs: Dennis Gallagher (dennis.gallagher at msfc.nasa.gov) Richard Denton (denton at comet.dartmouth.edu) Time: Monday, 3:30 to 5:30 pm Talks will present science results relating to derived magnetospheric densities and distributions. Here the talks focus not on the techniques, but instead on results from use of the various techniques. The idea is to cleanly separate technique talks from science results, so both receive appropriate emphasis. Techniques of Detecting Magnetospheric Density Chairs: Mark Moldwin (mmoldwin at igpp.ucla.edu) Peter Chi (pchi at igpp.ucla.edu) Time: Tuesday, 10:30 am to 12:00 pm Talks in this session will detail the new and improved techniques developed in recent years to determine magnetospheric densities and distributions. The intent is to bring everyone up to speed on the capabilities, assumptions, and limitations of these techniques. While presentations on any technique are welcome, special emphasis is placed on remote-sensing of the inner magnetosphere using networks of ground-based magnetometers. Inter-System Coupling: Observations Chairs: Pontus C:son Brandt (pontus.brandt at jhuapl.edu) Dennis Gallagher (dennis.gallagher at msfc.nasa.gov) Time: Tuesday, 1:30 to 3:00 pm The ionosphere, plasmasphere, superthermal electrons, ring current, and radiation belts all exhibit interactions that mutually effect their populations. This session will focus on those observations that show evidence of interactions between these regions and populations. These are the physical properties in the inner magnetosphere for which theoretical explanations are sought. Inter-System Coupling: Modeling Chairs: Mike Liemohn (liemohn at umich.edu) Anthony Reynolds (mark.reynolds at erau.edu) Time: Tuesday, 3:30 to 5:30 pm The ionosphere, plasmasphere, superthermal electrons, ring current, and radiation belts all exhibit interactions that mutually effect their populations. This session will focus on those theories that describe the interactions between these regions and populations. Emphasis will be placed on presentations that demonstrate the results of coupling population models. How these theories can or are used to address relevant observations will be discussed. Observations that are needed to advance and test theories will also be discussed. It is in this session that we can also invite talks directed toward the storm Campaign times. The magnetosphere and ionosphere under extreme conditions: Points of contact between global MHD simulations and IMS modeling and data(joint WG1/WG2, and GGCM) Chairs: George Siscoe (siscoe at bu.edu) Janet Kozyra (jukozyra at umich.edu) Time: Wednesday, 10:30 am to 12:00 pm MHD simulations are coming up with some possibly interesting results that bear on the inner magnetosphere during storm-time conditions. For example, all codes seem to show saturation of the polar cap potential for high solar wind driving electric field. Some codes also show large parallel potentials that might draw ions out of the ionosphere and raise them to ring-current energies, thus possibly supplying the ring current. WG1 Wrap-Up: Progress and Possibilities (joint WG1/WG2) Chairs: Dennis Gallagher and Mike Liemohn Time: Wednesday, 1:30 to 3:00 pm This session is devoted to discussing the status and direction of WG1 research. An attempt will be made to quantify and compare the results from the sessions above, and comprise a list of open/unresolved questions for the community to consider as part of their future research projects. WG2 Wrap-Up. Overflow, Summary, Future Plans (joint WG1/WG2) Chairs: Geoff Reeves and Richard Thorne Time: Wednesday, 3:30 to 5:30 pm This session is devoted to discussing the status and direction of WG2 research. +-------------------------------------------------------------------------+ |To add name to the mailing list or for a message to the GEM community | | please contact: editor at igpp.ucla.edu | | | |URL of GEM Home Page: http://www-ssc.igpp.ucla.edu/gem/Welcome.html | |Please update your e-mail address. | +-------------------------------------------------------------------------+
