Space Weather: Monitoring and Forecasting Equatorial Spread-F from the Pohnpei Radar

ATM-0001678 Tsunoda，Roland The PI建议进行一项为期三年的研究计划，以发展能够预测赤道扩散F(ESF)发生的短期预报能力。SRI提议增加波恩佩雷达观测站的传感器群，使其具备斜入射后向散射探测能力，以便利用后向散射探测系统收集亟需的电场和等离子体密度分布的同时测量结果。PRO已经有一个50兆赫的后向散射雷达、一个频率捷变雷达(FAR)和一个磁力计；所有这些都能够在一天中不同的(但重叠的)时间对赤道电场做出估计。OIB探测仪将提供两个半球内等离子体密度分布的描述。有了这套传感器，PRO将成为集成的ESF空间气象监测站的理想原型。SRI设想拟议的研究将是一项协同研究，将使以物理为基础的模型能够与关键数据集一起运行，并在模型输出的协助下适当解释数据。

ATM-0001678Tsunoda, RolandThe PI proposes to conduct a three-year research program to develop a short-term forecasting capability that can predict the occurrence of equatorial spread F (ESF). SRI proposes to augment the cluster of sensors at the Pohnpei Radar Observatory (PRO) with an oblique-incidence backscatter (OIB) sounding capability so that the PRO can be used to collect the much-needed simultaneous measurements of electric field and plasma-density distribution. The PRO already houses a 50 MHz backscatter radar, a frequency-agile radar (FAR), and a magnetometer; all are capable of contributing estimates of the equatorial electric field at different (but overlapping) times of the day. The OIB sounder would provide a description of the plasma-density distribution in both hemispheres. With this set of sensors, the PRO would become an ideal prototype for an integrated, ESF space-weather monitoring station. SRI envisions the proposed research to be a synergistic one that will enable physics-based models to be run with critical data sets, and data to be properly interpreted with the assistance of model outputs.
