*************************** ** THE GEM MESSENGER ** *************************** Volume 12, Number 12 May 17, 2002 ---------------------------------------------------------------- 2002 GEM Workshop IM/S Working Group 2 (Radiation Belts) Session Descriptions and Call for Papers ---------------------------------------------------------------- From: Geoff Reeves (reeves at lanl.gov) Richard Thorne (rmt at atmos.ucla.edu) Please find below descriptions for the Working Group 2 (Radiation Belts) sessions of the Inner Magnetosphere/Storms Campaign at this summer's GEM Workshop, plus information about the IM/S tutorials. 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. MONDAY Mon 9:15-10:00: IMS Tutorial: Dick Wolf Inner Magnetosphere Electric Fields Chair: Tom Hill Mon 10:30-12:00: Joint WG1, WG2 Inner Magnetosphere Magnetic and Electric Fields Co-chairs: A. Chan (aac at rice.edu), M. Liemohn (liemohn at umich.edu) 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. Mon 1:30-3:00: WG2 Recent Theory and Modeling of Radiation Belt Acceleration There are a variety of processes that have been suggested for the acceleration of radiation belt ions and electrons during storm conditions. This session will be devoted to recent theoretical work on the subject and how one might distinguish between the different mechanisms. Titles of potential contributions to this session should be forwarded to one of the following co-chairs R. Thorne (rmt at atmos.ucla.edu), A. Chan (aac at rice.edu) Mon 3:30-5:30: WG2 Radiation Belt Electron Loss Processes Loss of energetic from the outer radiation belts places severe constraints on the mechanisms for stormtime acceleration. Papers dealing with both theory and observation of loss processes during active conditions are solicited. Titles of potential contributions to this session should be forwarded to one of the following co-chairs R. Thorne (rmt at atmos.ucla.edu), K. Lorentzen (kirsten.r.lorentzen at aero.org) TUESDAY Tue 8:30-9:15 IMS Tutorial: Richard Horne Electron Acceleration and Loss in Earth's Radiation Belts: The Contribution of Wave-Particle Interactions Chair: R. Thorne Tue 10:30-12:00: WG2 Observations of Radiation Belt Dynamics During Storm and Non-storm Times The Earth's radiation belts exhibit their most dramatic changes during geomagnetic storms yet the precise relationship between geomagnetic storm activity and radiation belt dynamics remains unclear. We will examine the relationship between the processes that lead to enhanced geomagnetic activity and those that lead to enhanced radiation belt acceleration and loss. We will discuss to what extent storm time processes are necessary for or contribute to changes in the radiation belts. Titles of potential contributions to this session should be forwarded to one of the following co-chairs G. Reeves (reeves at lanl.gov), T. O'Brien (Thomas.P.OBrien at notes.aero.org) Tue 1:30-3:00: WG2: Solar Wind Drivers of Radiation Belt Events Radiation belt acceleration has been associated with changes in the solar wind. This session will be devoted to a discussion of the mechanism responsible for this connection. Titles of potential contributions to this session should be forwarded to one of the following co-chairs X. Li (lix at kitron.colorado.edu) G. Reeves (reeves at lanl.gov) Tue 3:30-5:30 WG2: End-to-End Models and Scenarios for Radiation Belt Events A variety of physical processes have been proposed as important for acceleration, transport, and loss in the radiation belts and many of the connections to associated geomagnetic activity and solar wind driving conditions have been established. However, there remains a need for models and descriptions of the chain of causality which couples solar wind conditions into the magnetosphere and ultimately into the radiation belts. Titles of potential contributions to this session should be forwarded to one of the following co-chairs G. Reeves (reeves at lanl.gov), M. Hudson (mary.hudson at dartmouth.edu) WEDNESDAY Wed 10:30-12:00 IMS (WG1 and WG2), GGCM: The magnetosphere under extreme conditions: Points of contact between global MHD simulations and IMS modeling and data Co-chairs: G. Siscoe, J. Kozyra Wed 1:30-3:00 WG1, WG2 Wrap-Up. Synthesis: Progress & Possibilities Co-chairs: D. Gallagher, M. Liemohn Wed 3:30-5:30 WG1, WG2: WG2 Wrap-Up. Overflow, Summary, Future Plans Co-chairs: G. Reeves, R.
