摘要
利用上海市大气复合污染自动监测站的观测数据,对上海地区两次典型污染过程期间(区域性细颗粒物污染过程和沙尘输送影响过程)细颗粒物的消光特性进行了统计分析。希望为进一步提升空气质量标准提供科学的依据。
Based on the observation in Shanghai multiple atmosphere pollution monitoring station,the extinction characteristics of fine particles were analyzed on two typical pollution processes,one was regional pollution process,the other was due to the transport of dust storm.The results indicated that the atmospheric extinction mainly caused by secondary aerosol,the extinction of secondary aerosol mainly come from scattering,the very low visibility occurred during fine particle pollution episode,but not occur during dust storm episode.
