GEM: CUSP Currents and Magnetopause Models

多机构美国全球变化战略的一个组成部分 研究计划（我们不断变化的星球，”地球委员会 Sciences，1991）正在理解和模拟地球空间 环境 作为其对美国全球贡献的一部分， 美国国家科学基金会的变化研究计划 大气科学部建立了一个新的研究 地球空间环境建模倡议，目标是 支持基础研究的动力和结构 地球空间的性质，导致全球建设 具有预测能力的地理空间模型。 第一次创业板运动的主题是 磁层边界，磁鞘超出它，和 从边界到磁层的连接 电离层 这笔赠款是为了实施一项全面的， 系统的计划，以测试已经提出的想法， 尖点流系统的整体结构和动力学， 它与区域1电流的关系。 该计划需要 开发和利用一系列定量的 尖点和极线模型。

An integral component of the multi-agency U.S. Global Change Research Program (Our Changing Planet," Committee on Earth Sciences, 1991) is understanding and modeling the geospace environment. As part of its contribution to the U.S. Global Change Research Program, the National Science Foundation's Division of Atmospheric Sciences has established a new research initiative, Geospace Environment Modeling (GEM), with the goal of supporting basic research into the dynamical and structural properties of geospace, leading to the construction of a global geospace model with predictive capability. The subjects of the first GEM campaign are the magnetospheric boundary, the magnetosheath beyond it, and the connection from the boundary through the magnetosphere to the ionosphere. This grant is to implement a comprehensive, systematic program to test ideas that have been suggested for the global structure and dynamics of the cusp current system and its relation to region 1 currents. The program entails developing and exploiting a hierarchial series of quantitative cusp and polar models.
