Earth's ionosphere, the final link in the solar-terrestrial connection, is fundamental to understanding conditions where solar perturbations result in damage to technological systems, such as power distribution systems, navigation aids, and communication networks. The investigators, recognizing this need, are creating a novel event-driven protocol adapting the Sondrestrom radar operational mode, data analysis, and data dissemination to the specific needs of space weather modeling and specification teams. Specifically, the Sondrestrom Radar Response System (SRRS) will enable operation during periods subsequent to detection of a coronal mass ejection, from beginning to end. Coronal mass ejections can be detected early with upstream monitors such as SOHO and WIND satellites, and their probability for terrestrial impact can then be better calculated. The design and implementation of the SRRS will greatly accelerate the development of near-real time electrodynamic specification tools for eventual integration into space weather forecasting models.

地球电离层是日地连接的最后一环，对于了解太阳扰动对诸如配电系统、导航辅助设备和通信网络等技术系统造成损害的条件至关重要。调查人员认识到这一需要，正在创建一种新的事件驱动协议，使Sondrestrom雷达的操作模式、数据分析和数据传播适应空间天气建模和规范小组的特定需求。具体地说，Sondrestrom雷达响应系统(SRRS)将自始至终在探测到日冕物质抛射后的一段时间内运行。日冕物质抛射可以通过SOHO和WIND卫星等上游监测设备及早检测到，然后可以更好地计算它们对地面影响的可能性。SRRS的设计和实施将极大地加速开发最终纳入空间天气预报模式的近乎实时的电动规范工具。
