南京市北郊工业区大气能见度消光因子研究
Research on the extinction factors of visibility in the north suburb of Nanjing industrial zone
摘要
Abstract
Based on the aerosol scattering coefficient observed by the integrating Nephelometer in the north suburb of Nanjing in four seasons 2009 -201 1,combined with data of NO 2 mass concentration,visibility,the contribution of extinction factors were.calculated.According to data of PM2.5 mass concentration,the relationship of PM2.5 ,relative humidity (RH )and visibility were analyzed,regression equations of PM2.5 ,visibility relative humidity and temperature were calculated.Results show that aerosol scattering accounted for the most of extinction factors,andβsa varied seasonally from the peak in winter to the bottom in summer.The concentration of PM2.5 between 1 50 μg· m-3 and 200 μg·m-3 ,haze has the highest incidence,reaching 97.7%.The extinction factors of visibility is different as the diffierentof relative humidity and PM2.5 mass concentration.关键词
