摘要

Abstract: The Chinese Meridian Project (CMP) is a major national science and technology infrastructure constructed in two steps. The first phase of the CMP has been operating for more than a solar cycle. From 2022 to 2023, utilizing the monitoring data collected by the CMP, scientists made major breakthroughs in fields of ionosphere, middle and upper atmosphere, and coupling between layers. The construction of the second phase of the CMP is nearly finished, and the project is expected to operate as a whole in 2025 after national acceptance of the second phase. The whole project was built in an architecture of so-called “One Chain, Three Networks and Four Focuses”. It is promising to make a three-dimensional observation of the whole solar-terrestrial space. The science community is looking forward to the great contribution of the CMP to space weather and space physics research.
