空气质量模型CMAQ的国内外研究现状

Application Status of Models-3/CMAQ in Environmental Management

空气质量模型是支撑环境管理与决策的重要工具。文章系统地回顾了空气质量模型的发展历程,重点介绍了多尺度空气质量模型CMAQ(Community Multiscale Air Quality Modeling System)在模拟预测臭氧、氮氧化物、硫氧化物和颗粒物等方面的国内外应用研究现状,同时指出CMAQ模型存在的问题、在我国环境管理中的应用以及未来空气质量模型的发展方向。研究表明,国内外对CMAQ模型的应用研究主要体现在3个方面:评价模型的模拟性能、模拟预测空气中污染物浓度以及研究各污染物的来源、产生机理及传输扩散过程。

Air quality model is an important tool to support environmental management and decision-making.The development of air quality model is introduced,especially the application and research at home and abroad of CMAQ in simulation and prediction of ozone,nitrogen oxides,sulfur oxides and particulate matter,also some disadvantages and application in en vironmental management of China as well as future development direction of air quality model are pointed out.It shows in that study that CMAQ model are mainly reflected in three aspects at home and abroad.
