How does the evolving global distribution of cold plasma govern the growth and propagation of waves that control energetic particle distributions & dynamics? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This session focuses on the influence of ambient plasma upon how waves are produced, and how they propagate. To be examined are the conditions for growth and propagation of various waves including EMIC, whistlers (hiss, chorus), ULF, especially the influence of ambient plasma properties (such as density, composition, and spatial structure on various scale sizes). ____MON 22 JUN____1:30 - 3:00pm PMI Breakout 1B: "Plasma Influence on Wave Particle Interactions" ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... How do ambient plasma properties such as temperature, density, and composition influence wave particle interactions? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This session focuses on how ambient plasma influences the waves-particle interactions themselves, examining how various plasma properties (such as density, composition, and spatial structure on various scale sizes) help govern the effectiveness of various waves in changing the energy or pitch angle of energetic particles. ____MON 22 JUN____3:30 - 5:00pm PMI Breakout 2: "Plume Transport, Evolution, and Influence" ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... How is eroded plasmaspheric material transported, how does it evolve and influence reconnection? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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. ____TUE 23 JUN____10:30am - 12:15pm PMI Breakout 3: "Plasma Density Structure and Evolution" ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... How do various plasma density structures originate and evolve during various phases of geomagnetic activity? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This session will focus upon outstanding questions about the dynamics of density structures in the plasmaspheric. Potential topics to be covered include, plume, fine structure & turbulence, plasma instabilities, refilling, ionosphere-thermosphere-plasmasphere interactions, and subcorotation. ____THU 25 JUN____3:30 - 5:00pm Joint PMI-CEDAR session: "Plasmasphere, Magnetosphere, Ionosphere: Overall System Response" ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... How do PMI processes influence the overall system response to storms? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This session will investigate the effects of redistribution of thermal ions (ionospheric and plasmaspheric) on the stormtime response of the overall magnetospheric system. The goal is to develop our understanding of the interaction among components of the larger system.

PET Focus Group Sessions at 2009 GEM Summer Workshop: Call for Presentations ---------------------------------------------------------------------------- From: Simon Wing Dear Colleagues, We would like to invite contributions to the PET focus group at the upcoming GEM workshop in Snowmass on June 21-26, 2009. The sessions will be held in a workshop (NOT AGU) style in which each speaker will be allotted time for a 2-3 slides, in order to ensure enough time for discussion. In order to encourage this, at least one of the slides should deal with unresolved issues. Speakers are encouraged to end the presentation with outstanding questions rather than a summary of what has/have been accomplished. It is expected that there will be three sessions: (1) Plasma entry into the Magnetosphere; (2) Plasma transport in the plasma sheet; and (3) M-I coupling and magnetotail transport. Sessions 1 and 2 have been tentatively scheduled on Jun 22 Tues afternoon while session 3 on Jun 23 Wed afternoon (See http://www.cpe.vt.edu/gem/index.html for the definitive schedule). 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 below. The following lists a brief description of these three sessions. Plasma Entry into the Magnetosphere The session invites contributions on (a) morphology (plasma properties, time scales, dawn dusk-asymmetry etc.) of plasma entry at the magnetospheric boundaries, (b) mechanisms, models, and observation specific for northward IMF, (c) mechanism and physics for southward IMF, and (d) entry rates and physics that processes the newly entering plasma (modification of distribution functions, local entropy, fluxtube entropy,..) Plasma Transport in the Plasmasheet This session focuses on the topics of (a) convective vs turbulent transport for northward and southward IMF, (b) constraints to convection (entropy, boundary conditions), (c) mapping of convection to the ionosphere, observations, ionospheric influence on convection or turbulence, (d) mechanisms and related observations for convection and turbulence in the plasma sheet (recovery phase, bursty bulk flows; steady magnetospheric convection, etc.). M-I Coupling and Magnetotail Transport The session invites contributions on (a) the morphology of ion outflow (Fluxes, outflow locations, concentrations and distribution in the plasma sheet), (b) time scales of ion outflow, (c) solar wind dependence, (d) heating of the cold ionospheric material, (e) ionospheric influence on transport in the magnetosphere.
