The Earth System Numerical Simulation Facility (“EarthLab”) is China's first advanced simulation facility with independent intellectual property rights, integrating hardware and software and oriented towards the Earth system. It possesses the capability to simulate various spheres of the Earth, finely describe physical, chemical and biological processes, and achieve bidirectional feedback coupling simulation between regional and global scales. The facility passed the national acceptance inspection in October 2022. The project legal entity is the Institute of Atmospheric Physics, and its construction site is located in Miyun District, Beijing.
