摘要
利用CE-318太阳光度计多波段观测资料,计算广州市区2010年11月亚运期间大气气溶胶光学厚度、散射系数及散射相函数,分析了广州亚运期间大气气溶胶光学厚度、波长指数和Angstrom混浊度系数的特征,并与近年同期历史数据进行了对比分析。结果表明,亚运期间受燃放烟花影响,测量点附近一段时间内气溶胶光学厚度明显增加,光学厚度逐日起伏变化明显;受交通负荷的变化影响,是否工作日和是否实施交通单双号限行都会影响光学厚度变化。
By using CE-318 photometers data, aerosol optical depth, scattering coefficient and phase function during the Guangzhou Asian Games in November 2010 are retrieved. Property of atmospheric aerosols optical depth, turbidity coefficient and wavelength exponent are analyzed, and the results are compared with those in the same historical period in recent years. The results show that aerosol optical depth increased as the discharge of fireworks during the Games. The change of aerosol optical depth was affected by the traffic loading, which was affected by the vehicle flow in workdays and holidays, and alternate travel limit to the cars with odd and even number of license tags.
