摘要: 棕碳 (BrC) 是大气中一类重要的吸光性含碳气溶胶, 因其对区域乃至全球辐射强迫和气候具有显著影响而备 受关注。然而, 对大气中 BrC 吸光特性缺乏全面认识是导致其辐射强迫评估不确定性的关键因素之一。通过梳理近 年来国内外 BrC 吸光特性的相关研究, 发现 BrC 来源、发色团组成、大气过程、 pH 条件和共存金属等都是影响 BrC 吸光特性的潜在因素, 系统总结了现有研究中对 BrC 吸光特性影响因素及影响机制的认识, 并对未来 BrC 吸光特性及 影响因素相关的研究方向提出了建议与展望.

Abstract: Brown carbon (BrC) is an important class of light absorbing carbonaceous aerosols in the atmosphere, which has attracted much attention because of its significant impact on regional and even global radiative forcing and climate. However, the lack of comprehensive understanding of the optical properties of BrC in the atmosphere is one of the key factors leading to the uncertainties of its radiative forcing evaluation. Researches on light-absorbing properties of BrC at home and abroad in recent years have been reviewed. It is shown that BrC sources, chromophore composition, atmospheric process, pH conditions and coexisting metal ions are potential influencing factors of the light absorption properties of BrC. The current understanding of the influencing factors and mechanism of BrC light absorption properties are systematically summarized, and suggestions and prospects for the future research on BrC light absorption properties and associated influencing factors are also put forward.

Key words: brown carbon, light absorption properties, influencing factors, research progress, perspectives
