Abstract & Keywords
Abstract: TheGround-based Space Environment Monitoring Network (Meridian Project for short) is a ground-based monitoring network system for the near-earth space environment. Geomagnetic (electrical) monitoring instruments, conventional radio monitoring instruments, large-scale radio monitoring instruments, cosmic ray monitoring instruments, optical monitoring equipment and interplanetary monitoring instruments have been deployed in 15 stations along 120ºE and 30ºN to continuously monitor the middle and upper atmosphere, ionosphere and magnetosphere from 20–30 km above the Earth’s surface to hundreds of kilometers above the Earth’s surface, as well as the interplanetary space that is a dozen Earth radii away from the Earth’s surface. Space environment data such as wind field, density, temperature, and composition of the middle and upper atmosphere, and the bulk speed in the ionosphere, magnetosphere, and interplanetary solar wind have been collected from 2010 to today, and a total of 163 datasets have been obtained. The data of the Meridian Project provides significant support for the studies on the characteristics of the space environment over China, the propagation of space weather events along the meridian chain, and the coupling between different domains of geospace environment, promotes the development of various existing geospatial models, and provides a large amount of business data for manned spaceflight and lunar exploration missions in China.
