子午工程，立体监测日地空间天气（迈向“十五五”的创新图景）

Core Insights - The "Ziwuyuan Project" has significantly improved China's capabilities in space weather monitoring and research, directly impacting the safety of spacecraft and high-tech systems [2][5]. Group 1: Project Overview - The Ziwuyuan Project aims to monitor changes in the solar-terrestrial space environment, providing support for space weather research and real-time forecasting [4][5]. - The project consists of a comprehensive monitoring network with 31 stations and 282 monitoring devices, making it the most extensive and capable ground-based monitoring network internationally [5]. Group 2: Technological Innovations - The project has developed a unique monitoring architecture characterized by a complete observation chain from the sun's surface to the Earth's surface, and a "three-network" layout for electromagnetic, middle and upper atmosphere, and ionosphere monitoring [2][3]. - Innovations include the use of a large aperture laser radar system to monitor the upper atmosphere, which was optimized through team collaboration and experimentation [3]. Group 3: Future Plans - The project will continue to implement the International Ziwuyuan Grand Science Plan, aiming to establish a comprehensive monitoring chain from 120°E to 60°W, facilitating all-weather observations of the solar-terrestrial environment [6]. - The goal is to enhance global responses to space weather disasters and promote peaceful utilization of outer space [6].
