*************************** ** THE GEM MESSENGER ** *************************** Volume 18, Number 13 May 5, 2008 ---------------------------------------------------------------------------- Sessions for New GEM Focus Group "Plasmasphere-Magnetosphere Interactions" ---------------------------------------------------------------------------- From: Jerry Goldstein and Joe Borovsky The 2008 GEM workshop will feature three sessions for the new Focus Group "Plasmasphere-Magnetosphere Interactions" (PMI). This focus group seeks to improve our understanding of the two-way coupling between the plasmasphere and magnetosphere. The Focus Group proposal is available at http://enarc.space.swri.edu/PAPERS/FTP/GEM/PMI-FG-Proposal_v2.doc or http://tinyurl.com/6d56vj The three (3) PMI sessions to be held at the upcoming 2008 GEM: ............................................................... Tue, 24 June, 10:30 a.m. - 12:15 p.m. PMI 1 (morning): "Waves in the Plasmasphere-Magnetosphere System" ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This session will examine the conditions for growth and propagation of various waves including EMIC, whistlers (hiss, chorus), ULF, and their importance to energetic particle dynamics. Emphasis will be placed upon the origin and influence of ambient plasma properties (such as density, composition, and spatial structure on various scale sizes). ............................................................... Tue, 24 June, 1:30 - 3:00 p.m. PMI 2 (afternoon): "Dynamics and Recirculation of Plasmaspheric Plumes" ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This session will examine the formation, dynamics, and fate of plasmaspheric plume plasma. Specific topics to be addressed include (but are not limited to): observation or modeling of cold, dense plasma mixed with magnetospheric plasma, plume plasma at reconnection sites or on open field lines, recirculation or redistribution of cold, dense plasma into the cusp and plasmasheet. ............................................................... Wed, 25 June, 3:30 - 5:00 p.m. PMI Planning: "Focus Group Planning Session (Open Discussion)" ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ In this session, we invite the GEM community to participate in an open forum to plan the PMI Focus Group. A strawman schedule will be presented for free-form discussion, but any interested parties are welcome to make brief (5-minute) presentations (including science) if they are relevant to planning this focus group. ...............................................................
