The Global Assimilation of Ionospheric Measurements (GAIM) model is extended to include ionospheric measurements from the incoherent scatter radar chain and to include neutral wind measurements from a variety of regularly operating Fabry-Perot Interferometer sites. Following data assimilation using Kalman filtering techniques pioneered by tropospheric modelers, the GAIM model is supplied to the NSF Center for Integrated Space Weather Modeling (CISM) as an ionosphere/plasmasphere component of their predictive, physics based sun-to-earth Space Weather model. A particular application of this model will describe the propagation of geomagnetic storm effects from high latitudes to low latitudes.

电离层测量的全球同化（GAIM）模型进行了扩展，包括电离层测量从非相干散射雷达链，并包括中性风测量从各种定期运行的法布里-珀罗干涉仪站点。 在使用由对流层建模者开创的卡尔曼滤波技术进行数据同化之后，GAIM模型被提供给NSF综合空间天气建模中心（CISM），作为其预测性的、基于物理学的日地空间天气模型的电离层/等离子体组成部分。 这个模型的一个特殊应用将描述地磁暴效应从高纬度向低纬度的传播。
