Call for Presentations at 2011 Joint CEDAR-GEM Workshop: "Magnetosheath Studies" Focus Group Sessions ---------------------------------------------------------------------- From: Steven Petrinec and Katariina Nykyri The Magnetosheath Focus Group will hold a 2-hour session on Tuesday, June 28 of the 2001 Joint CEDAR-GEM Workshop at the Santa Fe Convention Center. In addition to our pre-scheduled invited speakers (Michael Schulz and Hui Zhang) we invite participants to provide short presentations related to any of the magnetosheath focus group topics listed below. We also encourage both ionospheric and magnetospheric modelers and people using observations to participate in the development of the "GEM Magnetosheath Challenge", where the impact of specific magnetosheath conditions on magnetospheric and ionospheric dynamics is studied. Please send the title of your presentation to us by June 16th. The Primary Objectives and Expected Activities of the FG: 1. To produce more comprehensive models of large scale magnetosheath flow and field patterns, and geometry of the magnetosheath region 2. To improve understanding of magnetosheath plasma instabilities and wave particle interactions: Spatial distribution and characteristics 3. To develop a better understanding of the effects on magnetospheric dynamics due to processes occurring in the magnetosheath and due to characteristic magnetosheath properties. The focus group proposal with specific science questions can be found at http://aten.igpp.ucla.edu/gem/pdf/GEM_FG_MSheath_proposal.pdf . We especially encourage data-analysts utilizing in-situ spacecraft measurements from Themis and Cluster missions, theoretical modelers, global and local modelers to participate in this session. We will also entertain presentations of studies of magnetosheaths of other solar system bodies, as they relate to the terrestrial magnetosheath. ---------------------------------------------------------------------- 2. Call for Presentations at 2011 Joint CEDAR-GEM Workshop: "Substrom Expansion Onset: First 10 Minutes" (GEM FG 12) Sessions ---------------------------------------------------------------------- From: Vassilis Angelopoulos , Shin Ohtani , Kazuo Shiokawa , Andrei Runov We would like to invite contributions to the Substrom Expansion Onset: First 10 Minutes focus group session at the upcoming GEM-CEDAR workshop in Santa Fe, NM on June 27-July 1, 2011. We will have four sub-sessions to discuss the following topics 1. Onset timing 2. Onset signatures propagation in the magnetotail and to the ground 3. Ground-Space Mapping of Physical Processes 4. Substorm processes near transition between stretched and dipole field lines The workshop agenda and other information are available at http://www.cpe.vt.edu/gem/ Contributions based on data analysis, theory and modeling addressing the Focus Group topics are welcome. One of the goal of this focus group is to complete a matrix showing correspondence of each observation/model result to various substorm-onset physical models whether it gives positive or negative supports of the models. The current version of the matrix is available at the GEM Wiki page (http://www- ssc.igpp.ucla.edu/gemwiki/index.php/FG12._Substorm_Expansion_Onset:_Th e_First_10_Minutes). We would encourage a workshop presentation style with allotted time for maximum 3 slides in order to ensure enough time for discussions. Please provide us with the title(s) of your contribution(s) and the topic(s) to be addressed at your earliest convenience. ---------------------------------------------------------------------- 3. Call for Presentations at 2011 Joint CEDAR-GEM Workshop: "Space Radiation Climatology" Focus Group Sessions ---------------------------------------------------------------------- From: Paul O'Brien and Geoff Reeves The Space Radiation Climatology Focus Group will hold 2 2-hour sessions at the upcoming GEM-CEDAR Joint Workshop: 10-Noon and 1:30- 3:30 on Wednesday, June 29th. This is the final year of the focus group. The sessions will be organized around a few invited talks summarizing work over the life of the focus group, as well as open time for contributed talks on recent progress and plans for future investigations. The group co-chairs invite interested parties to contribute talks on climatological studies, data assimilation, long-term data sets, and related topics in the inner magnetosphere. A focus group wiki/agenda will be maintained at http://virbo.org/GEM_FG9_2011. Also, post your favorite recent and all-time climatology papers to the wiki! Please contact Paul O'Brien (paul.obrien at aero.org) or Geoff Reeves (reeves at lanl.gov) to schedule your contribution. The main wiki for the focus group can be found at http://virbo.org/GEMFG9 ---------------------------------------------------------------------- 4. "Nonlinear Plasma Effects in Auroral/Subauroral Plasmas" Sessions at 2011 Joint CEDAR-GEM Workshop ---------------------------------------------------------------------- From: Evgeny Mishin and Anatoly Streltsov We would like to announce a tentative Program of the "Nonlinear Plasma Effects in Auroral/Subauroral Plasmas" workshop at the upcoming GEM- CEDAR workshop in Santa Fe on June 27-July 1, 2011. The objective of this workshop is to make an assessment of the contribution of nonlinear plasma processes to the dynamics of the magnetosphere-ionosphere system with the emphasis on their effects on the energy transport and release in the ionosphere and magnetosphere at auroral and subauroral latitudes.
