摘要: 气溶胶与太阳辐射以及气溶胶与云之间的复杂相互作用, 使得气溶胶对气候有着重要的影响。评估气溶 胶对气候效应的影响依赖于气溶胶光学特性的准确信息。由于缺乏合适的仪器和方法, 气溶胶的光吸收一直是一 个难以准确测量的参量, 从而导致当前气溶胶对气候效应影响的评估仍带有很大的不确定性。光声光谱因其信号 只与样品的光吸收有关, 不受散射的影响, 因此非常适合气溶胶光吸收的测量, 被认为是测量气溶胶光吸收特性最 有效的方法之一。对光声光谱测量气溶胶光吸收特性的研究进展进行了综述, 并对近年来发展的新技术进行了重 点介绍和分析, 可为相关领域的研究人员提供参考。

Abstract: Because of its complex interactions with solar radiation and clouds, aerosols have an important impact on climate. Evaluating the impact of aerosols on climate effects relies on the accurate information of aerosol optical properties. Due to the lack of suitable instruments and methods, the light absorption of aerosols has always been a parameter that is very difficult to measure accurately, resulting in the great uncertainty in current assessment of the impact of aerosols on the climate. Since its signal is only related to the light absorption of the sample and is not affected by the scattering of the sample, photoacoustic spectroscopy is very suitable for measuring the light absorption of aerosols and is considered to be one of the most effective method for measuring the light absorption characteristics of aerosols. The research progress of the photoacoustic spectroscopy in measuring the light absorption characteristics of aerosols is reviewed, and the new technologies developed in recent years are introduced and analyzed, which can provide references for researchers in related fields.
