Chinese Academy of Sciences takes the lead in launching the International Meridian Circle Big Science Plan to deal with space weather problems – Passionategeekz

Passionategeekz According to June 16, on June 12, at the International Large Science Plan Forum of the Second Belt and Road Science and Technology Exchange Conference hosted by the Ministry of Science and Technology, the leading unit of the International Meridian Circle Program (IMCP), the National Space Science Center of the Chinese Academy of Sciences, signed a cooperation agreement with five international organizations, research institutions and universities that have recently joined the IMCP program (International Association for Science and Technology, the Korean Polar Research Center, the Nigerian National Space Research and Development Bureau, Thailand’s Xianhuang University, and Muni University of Munich) signed a cooperation agreement.Mark the scientific community’s initiative to launch the International Meridian Circle Big Science Plan。

According to the National Space Science Center of the Chinese Academy of Sciences, Earth space is the main area for human spaceflight, communications, navigation and other high-tech activities, as well as space development and utilization, and is the fourth environment closely related to human survival and development.Affected by solar activity, the earth’s space environment will undergo sudden, frequent and drastic changes.even triggering non-traditional natural disasters, called space weather.

Space weather is a global phenomenon, affecting the entire earth space and the activities and development of mankind, and is a common challenge facing all mankind. The United Nations, the United States, the European Union and others have formulated and implemented space weather action plans.To deal with the impact of catastrophic space weather events。

To cope with the challenge of the global problem of space weather, it is urgent to work with global space weather monitoring and research forces to focus on major scientific issues that affect the basic physical processes and changing laws of space weather, and carry out joint scientific research.

In March this year, the second phase of the meridian project, the major national scientific and technological infrastructure led by the National Space Science Center of the Chinese Academy of Sciences, officially passed the national acceptance, and built the most comprehensive space weather-based regional monitoring network in the world.Provides continuous and reliable monitoring data for the detection and guarantee of space environment over my country。

Based on the meridian project, Chinese scientists took the lead in proposing to establish the most complete meridian circle on land 120° east longitude ~ 60° west longitude . The meridian circle is mainly monitored, expanding to form a globally integrated multidisciplinary and multi-factor detection network.Realize three-dimensional observations of the entire latitude, all-weather and sun-distance spatial environment; Combined with space-based detection, we will conduct in-depth research on the characteristics and changes of the earth’s space environment, reveal its mechanism driven by the dual driving of solar outbreak and earth’s activities, and build a space weather model and high-precision forecast product driven by the international meridian circle data, providing a scientific basis for responding to global space weather disasters, peaceful use of space, and promoting the construction of a community with a shared future for mankind in the field of outer space.

The International Meridian Circle Science Plan aims to “build a global monitoring chain for the sun and earth system and decode the weather processes and laws of space”.Its scientific goals are:

• Cognitive system – Earth space system;

• Clarify two effects—the top-down effects from solar activity and the bottom-up effects from the earth’s system;

• Revealing the three major problems – the multi-element, multi-time and spatial scale characteristics and changes of the global and typical regions of the space environment, the propagation and evolution of the sun’s outbreak in the sun and earth space, the relationship between space weather and global changes, and the natural disasters on the earth.

In order to achieve scientific goals, the International Meridian Circle Science Plan plans to establish the “IMCP International Organization” – to coordinate and promote the implementation of the International Meridian Circle Science Plan and complete the “Carry out innovative research, organize collaborative monitoring, share data and information, and deepen cooperation and exchanges” and other four major tasks.

The International Meridian Circle Science Plan will be implemented for at least 11 yearscomplete the detection and research of the sun-earth space environment above a solar activity cycle, and build a space weather community with extensive participation and close cooperation between scientists around the world. Using diversified observation methods and global layout, we will promote major theoretical innovations and breakthroughs in the field of space weather, provide scientific support for improving the ability to defend against global space weather disasters, and provide unique solutions and contributions to the cognition of a livable earth and the peaceful use of outer space.

Passionategeekz learned from the official introduction that the International Meridian Circle Science Plan has been with 36 international organizations and foreign scientific research institutionsThe signing of a cooperation agreement or determining the intention to cooperate, 17 units from 7 departments and other domestic departments and 17 units participated, and received strong support from the Ministry of Science and Technology, the National Natural Science Foundation of China, the National Development and Reform Commission and the Beijing Municipal Government.
