摘　　要：1大气成分及相关特性变化观测研究1.24基于航测的云底气溶胶活化率和过饱和度估算2016年11月13日在北京地区上空存在持续稳定的层状云天气背景下,利用飞机开展了气溶胶粒径谱、化学组成、云滴谱等参量的垂直观测,研究了本次个例中云底气溶胶的活化能力。结果表明,探测期间北京地区为轻度污染天气,地面气溶胶浓度(0.11~3μm)达到了4600 cm-3。1 Observational studies of atmospheric composition and related properties 1.1 Advances in sunphotometer-measured aerosol optical properties and related topics in China:Impetus and perspectives Aerosol is a critical trace component of the atmosphere.Many processes in the Earth’s climate system are intimately related to aerosols via their direct and indirect radiative effects.Aerosol effects are not limited to these climatic aspects.
