GEM: ULF Wave Sigantures of the Dayside Magnetospheric Boundary

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 这个奖项的目的是建立一种方法， 通过使用ULF波作为一种 地磁场线的示踪器 利用航天器数据，波 与磁层顶有关的东西 这些数据将 然后与地面观测进行比较。

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.
