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. The goal of this award is to establis a method of identifying the location of the cusp by using ULF waves as a tracer of geomagnetic field lines. Using spacecraft data, wave pertinent to the magnetopause will be identified. This data will then be compared to ground-based observations.

由多个机构组成的美国全球变化研究计划(我们的地球变化研究计划，1991年成立的地球科学委员会)的一个组成部分是理解地球空间环境并对其进行建模。作为对美国全球变化研究计划的贡献的一部分，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)，目的是支持对地球空间动力学和结构属性的基础研究，从而构建具有预测能力的全球地球空间模型。第一次GEM运动的主题是磁层边界、其外的磁鞘以及从边界通过磁层到电离层的连接。该奖项的目标是建立一种通过使用ULF波作为地磁力线的跟踪器来识别尖点位置的方法。利用航天器的数据，将识别与磁层顶有关的波。然后将这些数据与地面观测进行比较。
