*************************** ** THE GEM MESSENGER ** *************************** Volume 19, Number 4 April 23, 2009 ---------------------------------------------------------------------------- GEM 2008/2009 MODELING CHALLENGE: Preparation for the GEM 2009 Summer Workshop ---------------------------------------------------------------------------- From: Masha Kuznetsova Aaron Ridley GGCM Metrics and Validation Focus Group is organizing modeling Challenge focusing on the inner magnetospheric dynamics and ground magnetic field perturbations. The goal of the Challenge is to evaluate the current state of the space physics modeling capability and to address the differences between various modeling approaches. Community Coordinating Modeling Center (CCMC) is supporting the Challenge. Lists of events and physical parameters for the metrics studies were selected at the GEM 2008 Workshop at Zermatt. Model output can be submitted to CCMC via Challenge web interface located at http://ccmc.gsfc.nasa.gov support/GEM_metrics_08/. CCMC will perform model/data comparisons for all submissions. Initial results based on early submissions were discussed at the GEM mini- workshop at the 2008 Fall AGU. Preliminary reports on analyses of geosynchronous parameters and ground magnetic field perturbations are available at the Challenge website (see address above). The Challenge results will be presented and discussed at the GEM 2009 Summer Workshop in Snowmass (http://www.cpe.vt.edu/gem/index.html). Joint publication by all participants and/or a series of back-to-back publications on the Challenge results are planned. Possible joint publications and future plans will be discussed at the GGCM Metrics and Validation Session at the GEM 2009 Workshop. To participate in the Challenge please submit your model results using the web interface prior to May 15, 2009. For more details, go to the Challenge web interface. Please send questions, comments and suggestions to: Masha Kuznetsova (Maria.M.Kuznetsova@nasa.gov) and Aaron Ridley (ridley@umich.edu). +-------------------------------------------------------------------------+ |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 | +-------------------------------------------------------------------------+
