大气化学机理的发展及应用

Development and Application of Atmospheric Chemical Mechanisms

大气化学机理是研究大气化学过程的重要手段和方法之一,也是发展空气质量模式必不可少的重要组成部分。作者综述了几种应用广泛的简化机理——碳键机理(Carbon Bond Mechanism,CBM)、加州大气污染研究中心机理(Statewide Air Pollution Research Center mechanism,SAPRC)、区域酸沉降机理(Regional Acid Deposition Mechanism,RADM)、区域大气化学机理(Regional Atmospheric Chemical Mechanism,RACM)以及详细化学机理——主要大气化学机理(Master Chemical Mechanism,MCM)和共同代表性中间体机理(Common Representative Intermediates,CRI)的发展及应用。对上述大气化学机理的产生、发展、包含的物种类型、集总方式等方面进行了对比分析,总结了采用烟雾箱数据评价大气化学机理的研究成果以及大气化学机理在模式发展方面的应用,并对大气化学机理的进一步发展与完善提出了需求。

Atmospheric chemical mechanism is one of the most important components to study photochemical processes and develop air quality models. The development and application of several atmospheric chemical mecha- nisms were summarized. The simplified chemical mechanisms include Carbon Bond Mechanism （CBM）, Statewide Air Pollution Research Center mechanism （SAPRC）, Regional Acid Deposition Mechanism （RADM）, and Regional Atmospheric Chemical Mechanism （RACM） which have been widely used in the past decades and the explicit chemi- cal mechanisms contain Master Chemical Mechanism （MCM） and Common Representative Intermediates （CRI） which were developed rapidly in the past few years. The history, species, and lump styles of these mechanisms were compared. Meanwhile, the research of the evaluation to chemical mechanism by using chamber experiment data and the application of these chemical mechanisms in model development also summarized. Besides, the further demand to the development and improvement of chemical mechanisms was put forward.
