Aerosol Extinction Characteristics and Analysis of Haze Formation in Suzhou City

  • 摘要: 为研究气溶胶消光特性对城市灰霾特征及形成的影响机制,采用2010年1月─2013年12月4 a的苏州市逐时散射系数、能见度、颗粒物质量浓度以及风速、风向、气温、气压、相对湿度等数据,对该市气溶胶散射系数、消光特性及影响因子进行了研究. 结果表明:苏州市气溶胶散射系数为(301.1±251.3)Mm-1,日变化呈双峰型,早高峰出现在07:00─08:00,晚高峰出现在20:00─21:00;其年内变化呈夏季低、冬季高. 气溶胶散射系数与ρ(PM2.5)的相关系数为0.77,高于与ρ(PM1)和ρ(PM10)的相关性,PM2.5散射效率为6.08 m2/g. 气溶胶散射系数受风速、风向等气象要素的影响:风速<4 m/s时,气溶胶散射系数下降迅速;风速在4~6 m/s时,气溶胶散射系数随风速下降缓慢. 苏州市气溶胶单次散射反照率平均值为0.84,散射消光比平均值为0.79,说明该地区气溶胶消光以散射性气溶胶为主. 气溶胶散射消光、气溶胶吸收消光、空气分子散射消光、NO2吸收消光分别占大气消光的82.33%、13.63%、2.72%和1.32%. 研究表明,对气溶胶散射消光贡献最大的非吸收性PM2.5是苏州市能见度下降、灰霾增加的最重要原因.
