The primary goal of this project is to determine the characteristics of the response of the ionospheric total electron content (TEC) to geomagnetic storms. The study will utilize the extensive ground-based, dual-frequency, Global Positioning System (GPS) measurements of TEC. A recent study has shown that by sorting F-region ionosonde data (NmF2) as a function of a new index of storm magnitude, a consistent repeatable picture begins to emerge in each season and latitude. The PIs will perform a similar analysis of total electron content, and compare and contrast the geophysical response with NmF2. This study will contribute to the understanding of the ionospheric response to geomagnetic storms. In the context of the National Space Weather Program, the work will provide the information to hopefully lead to an operational product for the benefit of a range of single frequency GPS users.

该项目的主要目标是确定电离层总电子含量（TEC）对地磁暴的响应特征。 该研究将利用 TEC 广泛的地面双频全球定位系统 (GPS) 测量。 最近的一项研究表明，通过根据新的风暴强度指数对 F 区电离探空仪数据 (NmF2) 进行排序，每个季节和纬度开始出现一致的可重复图像。 PI 将对总电子含量进行类似的分析，并将地球物理响应与 NmF2 进行比较和对比。 这项研究将有助于了解电离层对地磁风暴的响应。 在国家空间天气计划的背景下，这项工作将提供信息，有望开发出一种可操作的产品，使一系列单频 GPS 用户受益。
