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.

ATM-0001678 Tsunoda，Roland PI建议进行一项为期三年的研究计划，以开发能够预测赤道扩展F（ESF）发生的短期预测能力。 SRI建议增加波恩佩雷达观测站（PRO）的传感器集群，使其具有入射后向散射（OIB）探测能力，以便PRO可以用于收集急需的电场和等离子体密度分布的同时测量结果。 PRO已经安装了一个50 MHz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的不同（但重叠）时间对赤道电场进行估计。 OIB探测器将提供两个半球等离子体密度分布的描述。 有了这套传感器，PRO将成为一个综合的ESF空间气象监测站的理想原型。 SRI设想拟议的研究是一个协同的研究，将使基于物理的模型与关键数据集一起运行，并在模型输出的帮助下正确解释数据。
