GEM: A Concept Study for a Global MHD-Based Geospace General Circulation Model

该建议将发展基于mhd的全球地球空间环流模型（GGCM）的概念。最终的产品将是一个可供科学界使用的设施。用途可以包括测试模型的变化和开发基本MHD核心之外的模块。这个项目的最终产品将是概念的定义和结构。这种概念研究的重要性在于帮助确定在协调一致的GGCM开发工作中进行的最佳实施策略，这可能在不久的将来进行。

This proposal will develop the concept for an MHD-based GGCM (Global Geospace Circulation Model). The end product would be a facility, which could be used by the science community. Use could include testing changes in the models and the development of modules for addition to the basic MHD core. The end product of this project will be the definition and structure of the concept. The importance of such a concept study is to help determine the best implementation strategy to undertake in a concerted GGCM development effort, which may be mounted in the near future.
