Storm-Time Inner Magnetosphere-Ionosphere Convection (SIMIC) Focus Group: Call for Presentations at the 2013 GEM Summer Workshop ---------------------------------------------------------------------- From: Joseph Baker Dear Colleagues, This year's GEM Summer Workshop marks the initiation of a new Focus Group to examine "Storm-Time Inner Magnetosphere-Ionosphere Convection (SIMIC)". The SIMIC Focus Group will bring together observations and modeling to examine the coupled dynamics of the inner magnetosphere and ionosphere during geomagnetic storms. Recent improvements in modeling and ground- and space-based instrumentation allow this topic to be examined with unprecedented spatial and temporal resolution and coverage. Some examples of relevant parameters of interest include: plasma distributions, magnetic topology, convection electric fields, and current systems. More details about the SIMIC Focus Group can be found at: http://aten.igpp.ucla.edu/gemwiki/index.php/FG:_Storm-Time_Inner_Magnetosphere-Ionosphere_Convection We invite short presentations that highlight one or more of the following themes: 1) Improvements in self-consistent physics-based simulations of the coupled inner magnetosphere-ionosphere system during geomagnetic storms. 2) Instrumentation which can be used to examine storm-time magnetosphere-ionosphere coupling over large spatial scales and validate the simulations (e.g. magnetometers, radars, imaging, GPS receivers, etc.) 3) Any other discussion topics relevant to articulating an appropriate scope and emphasis for this Focus Group. (Since this is the first year, we are open to any comments or suggestions about how to move forward most effectively.) The SIMIC Focus Group will hold two sessions on Thursday afternoon and Friday morning. We have deliberately scheduled the sessions for late in the week to benefit those people who aim to attend both GEM and CEDAR. If you would like to give a SIMIC presentation, please email Joseph Baker (jo.baker at vt.edu) and Stan Sazykin (sazykin at rice.edu) with a working title and short description of your talk. Here's to a great SIMIC kick-off! Joseph Baker, Stan Sazykin, Mike Ruohoniemi, Peter Chi, Mark Engebretson ---------------------------------------------------------------------- 2. GGCM Metrics and Validation Focus Group: Call for Presentations at the 2013 GEM Summer Workshop ---------------------------------------------------------------------- From: Tim Guild , Howard Singer, and Lutz Rastaetter The GGCM Metrics and Validation Focus Group solicits short contributions to three planned sessions at the upcoming GEM meeting in Snowmass, Colorado, on Thursday and Friday, June 20-21. The session descriptions are below. If you have a topic to discuss, please send us a draft title so that we can begin to put together a program; however, in the spirit of GEM, participation and brief, last-minute informal presentations are always welcome. Session 1: New Validation Results and Methods In this session we solicit short presentations focusing on all aspects of data-model comparisons. Welcomed themes could include geospace model validation using regional ground magnetometer indices, model responses to dynamic magnetopause boundaries, long-term "climatological" model validation, using multi-variate metrics to assess model performance, or any related contribution. Session 2: How Validation Studies Guide Model Improvements: In this session, we solicit short presentations on specific examples of how discrepancies between models and observations have led to a better understanding of the physics that needs to be incorporated into models. Studies, or ideas, on studies involving model sensitivity to inputs and various model parameters are welcome. The session will include a discussion on better ways to design metrics and validation studies to uncover missing physics in models. Session 3: Validation of MHD models Coupled with other modules such as the Ring Current and Polar Outflow In this session we will investigate recent advances in the development of coupled models of the magnetosphere, inner magnetosphere, the plasmasphere/polar wind, and the ionosphere/thermosphere. We solicit short presentations on methods to link models, validate the outputs and constrain coupled model systems using observations. Emphasis should be placed on new physical processes that are described by the coupled models and on effects that remain out of scope and that limit the effectiveness and stability of the coupling.
