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.

多机构美国全球变化研究项目（我们不断变化的星球，地球科学委员会，1991年）的一个组成部分是理解和模拟地球空间环境。作为对美国全球变化研究计划的一部分，美国国家科学基金会大气科学部建立了一项新的研究计划——地球空间环境建模（GEM），其目标是支持对地球空间动力学和结构特性的基础研究。从而构建具有预测能力的全球地球空间模型。第一个GEM活动的主题是磁层边界、磁层边界之外的磁鞘，以及从磁层边界到电离层的连接。这项拨款是为了实施一项全面、系统的计划，以测试有关尖端洋流系统的全球结构和动态及其与1区洋流的关系的想法。该计划需要开发和利用一系列定量尖端和极地模型。
