CTOnews.com, November 17, according to CCTV News, the first Earth system numerical Simulation Science Conference was held in Beijing on November 17. At the meeting, the Institute of Atmospheric Physics of the Chinese Academy of Sciences released China's first "complete" earth system numerical model with independent intellectual property rights, and announced the release of its source code, indicating that the development of China's earth system model opens a new paradigm of collaborative development and win-win cooperation.

It is reported that the model includes a complete climate system and ecological environment system, which integrates eight subsystem models, including atmospheric circulation, ocean circulation, land surface processes, sea ice, aerosol and atmospheric chemistry, vegetation dynamics, terrestrial biogeochemistry and marine biogeochemistry, and uses couplers to realize the exchange of matter and energy between the earth's layers.

Based on the systematic "numerical simulation" of this model, it can be used to explore and understand the evolution law of climate and environment, study the mechanism of multi-layer interaction, and predict the changes of the earth system in the future. to provide decision-making basis and scientific and technological support for major national strategic needs such as disaster prevention and mitigation and dealing with future climate change.

The model is jointly developed by top domestic teams in related fields, brings together multi-disciplinary research forces such as geoscience, mathematics, computational science, and so on, and is a model of interdisciplinary integration. It is also the core software of the "Earth system numerical Simulation device" of the national major scientific and technological infrastructure, with a total of about 2.7 million lines of program code, known as the "Earth Laboratory".

Since 2020, the model has participated in the sixth International coupled Model comparison Program (CMIP6) numerical simulation experiment, and its simulation performance for tropical wind field, AMOC (Atlantic Meridional overturning Circulation) and ENSO (El Nino-Southern Oscillation) is among the highest in the world.

CTOnews.com learned from the Institute of Atmospheric Physics of the Chinese Academy of Sciences that the numerical simulation of the earth system is recognized as one of the frontier fields of geoscience development in the world. It is the deep intersection and integration of atmospheric science, marine science, geography, ecology, environmental science and mathematics, computational science and other disciplines. It is applied to deeply understand the basic laws of the evolution of the earth system and scientifically predict the disasters and evolution of the earth system. It also provides a scientific basis for related management and serves the sustainable development of social economy.

The Institute of Atmospheric Physics of the Chinese Academy of Sciences originated from the Institute of Meteorology of the National Academia Sinica founded by the famous meteorologist Zhu Kezhen in 1928. In January 1950, the Chinese Academy of Sciences merged some scientific research institutions such as meteorology, geomagnetism and earthquake to form the Institute of Geophysics of the Chinese Academy of Sciences. In January 1966, according to the needs of the development of meteorological cause in China, the Chinese Academy of Sciences decided to separate the meteorological research office from the Institute of Geophysics and formally established the Institute of Atmospheric Physics of the Chinese Academy of Sciences. The Atmospheric Institute is the first highest academic institution to study meteorological science in modern Chinese history. At present, it has developed into a comprehensive research institution of atmospheric science covering all branches of atmospheric science.
