A review of the effects of relative humidity on aerosol scattering properties

摘要: 大气气溶胶的散射吸湿增长特性反映了相对湿度对气溶胶散射能力的影响。研究气溶胶散射吸湿增长对于评估气溶胶辐射强迫、了解气溶胶对大气能见度的影响具有重要意义。文中对气溶胶散射吸湿增长特性的研究意义、监测方法、中外研究进展、参数化拟合和模型模拟等方面进行了系统回顾和总结，并对未来发展方向做出展望。中国在该领域开展的研究数量偏少，广泛开展气溶胶散射吸湿增长特性研究十分必要。

Abstract: Enhancement factors for scattering properties reflect the influence of relative humidity (RH) on aerosol scattering properties. Studies of the dependence of aerosol scattering properties on relative humidity are essential to evaluate aerosol direct radiative forcing and atmospheric visibility. A comprehensive review about the measuring technique, observations at home and abroad, empirical equations and modeling methods is presented. Few studies concerning this field have been carried out in China. Thereby it is imperative to comprehensively investigate effects of RH on aerosol scattering properties.
