This is a proposal to develop a storm-time correction map that will improve the ability of existing models to specify the variations in ionospheric density associated with magnetic storms. During a geomagnetic storm, the ionosphere can be severely altered causing disruptions to communication and navigation systems. This project takes advantage of the new understanding of the response of the upper atmosphere to geomagnetic storms to develop a correction map for the mid and high latitude ionosphere. Two approaches are planned. The first involves the use of a physically-based Coupled Thermosphere Ionopshere Model, the second involves capturing the essential physics in an empirical description. The study will determine the most successful prescription for magnetospheric forcing of the upper atmosphere and will develop a measure of accuracy of prediction.

这是一项制定风暴时间校正图的提议，将提高现有模型的能力，以确定与磁暴有关的电离层密度变化。 在地磁暴期间，电离层可能会发生严重变化，导致通信和导航系统中断。 该项目利用对高层大气对地磁暴反应的新认识，绘制中高纬度电离层校正图。 计划采取两种办法。 第一个涉及到一个物理为基础的耦合热层电离层模型的使用，第二个涉及到捕获的经验描述的基本物理。 这项研究将确定高层大气磁层作用力的最成功的方法，并将制定预测准确性的衡量标准。
