              Conveners: Jerry Goldstein & Maria Spasojevic

              The Focus Group "Plasmasphere-Magnetosphere Interactions" (PMI) hosted FIVE (5) sessions at the 2009 GEM Summer Workshop:


              Monday, 22 June 2009

            • PMI Breakout 1A: 10:30am - 12:15pm........ "Wave Growth and Propagation"
                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).
            • PMI Breakout 1B: 1:30 - 3:00pm........ "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 wave-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.
            • PMI Breakout 2: 3:30 - 5:00pm........ "Plume Transport, Evolution, and Influence"
                How does eroded plasmaspheric material get transported, 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.


              Tuesday, 23 June 2009

            • PMI Breakout 3: 10:30am - 12:15pm........ "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.


              Thursday, 25 June 2009

            • Joint PMI-CEDAR session: 3:30 - 5:00pm........ "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.

            TOPIC (II): PLUME DYNAMICS & RECIRCULATION       

            •         A.         How is eroded plasmaspheric material transported throughout the magnetosphere, and how does it evolve?
            •         B.        How do plumes influence the reconnection process, and what are the implications for solar-wind-magnetosphere coupling?

            TOPIC (III): PLASMA DENSITY STRUCTURE & EVOLUTION       

            •         A.         How do density structures of various spatial and temporal scales form and evolve?
            •         B.        How does plasmaspheric filling vary spatially and on time scales from hourly to solar cycle?
