*************************** ** THE GEM MESSENGER ** *************************** Volume 15, Number 15 April 30, 2005 -------------------------------------------------------------------------- Call for Participation: Inner Magnetosphere/Storms Campaign IM/S Assessment Challenge Data and Modeling Presentations At the Joint CEDAR/GEM 2005 Workshop, Santa Fe, NM, June 27 - July 1 -------------------------------------------------------------------------- From: Mike Liemohn The Inner Magnetosphere/Storms (IM/S) Campaign will continue the IM/S Assessment Challenge (IMSAC) at the Joint CEDAR-GEM Workshop this summer (June 27-July 1). All interested data analysts and modelers are welcome to participate in the discussions of the plasmasphere, ring current, and electron radiation belts for the selected storms. Several sessions will be devoted to the presentation of IMSAC results. Please begin planning your contributions to these sessions. The IMSAC is the climax of the IM/S Campaign of the NSF's Geospace Environment Modeling (GEM) program. The purpose of the IMSAC is two-fold: (1) assess our current ability to simulate the inner magnetosphere during a magnetic storm, and (2) assess our current understanding of the physics of the inner magnetosphere. Principal outcomes of this effort are the consolidation of what is known about the inner magnetosphere and the identification the critical, unresolved issues. A few magnetic storms were carefully selected for intensive data analysis and modeling efforts among the plasmasphere, ring current, and radiation belt communities. For the plasmasphere and ring current, the selected events are April 21, 2001 and October 21-23, 2001. For the radiation belts, the selected events are October 21-23, 2001 and September 4-9, 2002. A special feature of the IMSAC is that several measurements were selected as a core data set for each plasma population, and modelers are asked to compare against this core data set for each simulation result they submit to the challenge. A special issue of JGR-Space has been proposed for the consolidated publication of IMSAC results. The manuscript deadline is tentatively scheduled for November 30, 2005. There is a website for the IMSAC with more information about the challenge: http://csem.engin.umich.edu/GEM_IMS/ There is also an ftp site for IMSAC, where one can find the relevant data for the plasmasphere, ring current, and radiation belt components of the challenge: ftp://ftp.nsstc.org/gem/ More data could become available here in the near future.
