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.

电离层测量值（GAIM）模型的全球同化被扩展到包括不连贯散点雷达链中的电离层测量值，并包括来自各种定期运行的Fabry-Perot干涉仪位点的中性风测量。 在使用对流层建模者开创的Kalman滤波技术的数据同化后，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，物理基于物理的太阳至美洲太空天气模型的电离层/等离子体组成部分。 该模型的特殊应用将描述从高纬度到低纬度的地磁风暴效应的传播。
