Call for Presentations at 2010 GEM Summer Workshop: Dayside FACs and Energy Deposition--Dayside FED ---------------------------------------------------------------------- From: Delores Knipp, Stefan Eriksson, Geoff Crowley, Ramon Lopez We would like to invite contributions to the Dayside FAC and Energy Deposition (FED) focus group at the upcoming GEM workshop in Snowmass on June 21-25, 2010. This new focus group is organizing to explain the relation between enhanced dayside Poynting flux and field-aligned currents, sources of field-aligned currents in the solar wind and magnetosphere and their impacts in the ionosphere-thermosphere system. The GF goals and other information are at: http://aten.igpp.ucla.edu/gemwiki/index.php/FG:_Dayside_FACs_and_Energy_Deposition The FED focus group will hold two sessions at the upcoming GEM Workshop (June 20-25) in Snowmass, covering data, theory, modeling aspects of the following topics: - Dayside Poynting Flux, Joule Heating and Their Relation to Field Aligned Currents - Particle Energy Deposition on the Dayside - Dissipation of Magnetospheric Energy in the Dayside Thermosphere - Thermospheric Density Enhancements and Traveling Atmo/Iono- spheric Disturbances - Solar Wind Drivers for Extreme Dayside Poynting Flux Events We will discuss the types of NSF GEM investigations to bring this forward toward a conclusion by 2012. The sessions will be held in a workshop (NOT AGU) style in which each speaker will be allotted time for a 3-4 slides, in order to ensure enough time for discussion. At least one of the slides should deal with unresolved issues. Speakers are encouraged to end their presentation with outstanding questions that could provide a basis for a session at next year's joint GEM-CEDAR meeting. Both sessions have been tentatively scheduled on Monday Jun 21 (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.

Space Radiation Climatology at the 2010 GEM Summer Workshop ---------------------------------------------------------------------- From: Paul O'Brien (paul.obrien-at-aero.org), Geoff Reeves (reeves-at-lanl.gov), Bob Weigel (rweigel-at-gmu.edu), and Reiner Friedel (friedel-at-lanl.gov) It's almost time for the GEM Summer Workshop, joint with CEDAR. The Space Radiation Climatology Focus Group (FG9) will meet for three breakout sessions: two on Thursday June 24th: 1:30-3:30 and 3:30-5, and one on Friday, the 25th, 10:30-12:15. We will be discussing the past year's results in reanalysis, data assimilation, climatology models, and long-term data/analysis. One of our sessions (the first one) will be joint with the new radiation belt focus group. We already have a number of exciting talks lined up, but there's plenty of room for more. We encourage interested parties to send talk ideas to Paul O'Brien, Bob Weigel, and/or Reiner Friedel (Geoff will not be able to attend this year). If you are presenting an FG9-related poster, please sign up for the **Thursday** Poster Session and advertise on the Wiki. http://www.virbo.org/GEM_FG9_2010 To view the FG9 email archive or to join the email group, go to http://groups.google.com/group/gem-2007-space-radiation-climatology- fg9 ---------------------------------------------------------------------- 3. JASTP "Modes of Magnetospheric Response" Special Issue ---------------------------------------------------------------------- From: Larry Kepko and Bob McPherron Dear colleagues, In response to our call for presentations, The Journal of Atmospheric and Solar-Terrestrial Physics (JASTP) has approached the "Modes of Magnetospheric Response" focus group about developing a special issue from the results of the 2010 Workshop. Bob McPherron and I both agree that this is a wonderful opportunity to highlight not just the work of the group but the GEM program as well. For example, the Reconnection Challenge provided much positive visibility for GEM, and we would like to reproduce that kind of exposure here. Special issues such as these often provide more value than just the science content of the papers themselves. As a first step, please let us know if you are interested in contributing a paper to this special issue. Note that we are not at this time looking for a firm commitment -- we just need a show of hands. At the GEM workshop, we will again poll the community to see if there is enough interest to proceed. Only after this second round of polling will we provide JASTP a definitive answer on whether we will move forward. As a reminder, I am reproducing the 2010 call for presentations below, but papers need not be limited to these particular topics. Please contact either Bob Mcpherron or myself if you are interested. Best regards, Larry Kepko and Bob McPherron (Below is the call for presentations at the 2010 GEM Summer Workshop: "The Modes of Magnetospheric Response" Focus Group) The Modes of Magnetospheric Response focus group will hold three sessions at the upcoming GEM Workshop (June 20-25) in Snowmass, CO, covering the following topics: 1. Dayside observations during sawtooth events, the role of polar cap saturation, and implications for the magnetospheric response. Specifically, are particle injections on the dayside dispersionless or dispersive? Can sawtooth observations be understood as substorms that penetrate deep into the inner magnetosphere, or do sawtooth represent a fundamentally different state of the magnetosphere? We particularly encourage participants to bring data that addresses the issue of dayside injection and/or dipolarization. 2. Non-linear coupling and the role of pre-conditioning in determining the response mode. Example topics and questions include: Systematic errors in activity indices; Seasonal effects on coupling functions; mass-loading effects on convection; The storm/substorm/SMC relationship. 3. Magnetospheric response and solar wind energy transfer during the extreme solar minimum. This focus group has as its aim the improvement of knowledge of the physical mechanisms that provide different dynamical modes of response of the magnetotail to the solar wind. These include substorms, steady magnetospheric convection, sawtooth injection events, pseudo breakups, and poleward boundary intensifications.

Few more scholarships available for Ph.D in Engineering Physics at Embry-Riddle Aeronautical University ---------------------------------------------------------------------- From: Katariina Nykyri (nykyrik@erau.edu) We still have couple of scholarships available for students with M.S degree in physics, engineering physics, space physics or related field fields to start our Ph.D program in Fall 2010. The scholarship covers a full tuition and 20,000 USD annual stipend. The first year consists of taking the core courses after which students will find an advisor to do their thesis research with. Please see formal program requirements and more information at: http://www.erau.edu/db/degrees/phd-engineeringphysics.html Please send your application package and/or contact Dr. John Olivero (oliveroj@erau.edu) or Dr. Mahmut Reyhanoglu (reyhanom@erau.edu) for more details. +-------------------------------------------------------------------+ |To subscribe GEM Messengers, send an e-mail to | | | | with the following command in the body of your e-mail message: | | subscribe gem | |To remove yourself from the mailing list, the command is: | | unsubscribe gem | | | |To broadcast a message to the GEM community, please contact | | Peter Chi at | | | |Please use plain text as the format of your submission. | | | |URL of GEM Home Page: http://aten.igpp.ucla.edu/GemWiki | |Workshop Information: http://www.cpe.vt.edu/gem/index.html | +-------------------------------------------------------------------+
