尽管近年来取得了令人印象深刻的进展，但目前我们对有机气溶胶的组成、物理化学性质、来源和转化特征的了解仍然相当有限，其对环境的影响仍然高度不确定。本文讨论了与有机气溶胶有关的问题及其对大气过程和气候的影响，并对这些问题进行了优先排序，为该领域今后的活动提供了基础。讨论了四个主要的专题领域：1)油酸的来源；2)油酸的形成、转化和清除；3)油酸的物理、化学和混合状态；4)油酸的大气模拟。本文综述了这四个领域的关键问题和研究重点，并针对每个主题领域提出了有待进一步研究的问题。此外，还努力制定一套基本的、一致的、普遍适用的术语和定义，以便在不同的尺度和学科上连贯地描述大气办公自动化。
In spite of impressive advances in recent years, our present understanding of organic aerosol (OA) composition, physical and chemical properties, sources and transformation characteristics is still rather limited, and their environmental effects remain highly uncertain. This paper discusses and prioritizes issues related to organic aerosols and their effects on atmospheric processes and climate, providing a basis for future activities in the field. Four main topical areas are addressed: i) sources of OA; ii) formation transformation and removal of OA; iii) physical, chemical and mixing state of OA; iv) atmospheric modelling of OA. Key questions and research priorities regarding these four areas are synthesized in this paper, and outstanding issues for future research are presented for each topical area. In addition, an effort is made to formulate a basic set of consistent and universally applicable terms and definitions for coherent description of atmospheric OA across different scales and disciplines.
