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 for support to deploy an array of magnetometers at cusp/cleft latitudes in a joint effort with Augsburg College. The purpose of the array is to study ionospheric waves associated with the magnetospheric cusp and neighboring regions. In association with the radar system that will be operating in the same area, this magnetometer array will provide high time resolution, two-dimensional data in the electrodynamics of cusp convection.

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。这笔拨款用于支持与奥格斯堡学院共同努力，在尖端/裂缝纬度部署磁力计阵列。该阵列的目的是研究与磁层尖端和邻近区域相关的电离层波。与将在同一地区运行的雷达系统相结合，该磁力计阵列将提供尖端对流电动力学的高时间分辨率二维数据。
