Development of regional atmospheric environment modeling system(RegAEMS)

Numerical simulation is an important means to carry out studies related to urban atmospheric chemistry and environmental meteorology, regional air pollution and climate change. The regional atmospheric environment simulation system RegAEMS is one of the air quality models independently developed in our country. It includes mesoscale meteorological models(MM5/WRF/TAPM) and atmospheric environment model(AEM), and can be coupled with the regional climate model RegCM. It can be used for acid deposition, photochemical smog, fine particles, and heavy metal studies, including the formation mechanism, simulation prediction, management and control measures, and environmental assessment and climatic effect of air pollution. This paper mainly introduces the development history, frame structure and main performance. Most importantly, the latest improvement and simulation verification of RegAEMS was addressed. It indicated that the improvement of RegAEMS has strong ability in study and operation on regional complex air pollution simulation and control.
