| 摘 要： | 2007年11月,利用CE-318太阳光度计对南京仙林地区进行了气溶胶光学特性的观测实验.详细讨论了气溶胶光学厚度反演的原理与方法,采用Langley法对CE-318进行了现场定标,利用观测数据反演了气溶胶光学厚度和Angstrom系数.分析得出了550 nm处的光学厚度平均为0.5183,浑浊度系数β平均值为0.2325,波长指数α平均值为1.3373.分析了光学厚度的日变化和逐日变化,讨论了变化的原因.对Angstrom参数的分析表明仙林地区气溶胶以中小粒子为主,这对于分析和监测南京地区大气污染、改善空气质量具有一定的积极意义.

| Abstract: | An observation experiment of aerosol optical characteristics was carried out with automatic sun tracking photometer CE-318 in November, 2007. The theory and methods of aerosol optical depth(AOD) retrieving are discussed in detail. The CE-318 was calibrated using Langley method. AOD and Angstrom parameters were retrieved based on the obtained data. The average AOD is 0.5183 at 550 nm, and the average Angstrom parameters EQUATION] and EQUATION] are 0.2325 and 1.3373, respectively. The daily variation of AOD and the cause are discussed. The results show that small particles are primary in Xianlin region, Nanjing, and it is important for analyzing and monitoring air pollution and improving air quality of Nanjing. |
