Collaborative Research: The Low-latitude Ionosphere and the Development of Forecasting Techniques Using the Low-latitude Ionosphere Sensor Network (LISN) Distributed Observatory

该项目将继续运行低纬度电离层传感器网络，并利用其区域测量数据调查低纬度电离层结构和动态的日常变化和形成情况。LISN是一个分布式观测站，由主要安装在南美洲西半部的全球定位系统接收器、磁通门磁力计和垂直入射脉冲电离层雷达电离层探测仪组成。根据这项赠款开展的工作将收集、存储和传播实时电离层观测数据（即即时预报），并开展专门的活动和调查，以发展南美洲低纬度电离层电动力学和稳定性的预测能力。

This project will continue operating the Low-latitude Ionosphere Sensor Network (LISN) and utilize its regional measurements to investigate the day-to-day variability and formation of structures and dynamics in the low-latitude ionosphere. LISN is a distributed observatory composed of GPS receivers, flux gate magnetometers, and Vertical Incidence Pulsed Ionospheric Radar (VIPIR) ionosondes installed principally in the western half of South America. The work carried out under this grant will collect, store, and disseminate real-time ionospheric observables - a nowcast - and to conduct dedicated campaigns and investigations leading toward developing a predictive capability - a forecast - of the electrodynamics and stability of the low- latitude ionosphere over South America.
