Inversion and Analysis of Atmospheric Aerosol Optical Depth in Gobi Area of Xinjiang
大气光学 气溶胶光学厚度 波长指数 反演 atmospheric optics aerosol optical depth Angstrom wavelength exponent inversion
摘要
利用CE318型太阳光度计测量气溶胶光学厚度和波长指数的反演计算方法,选择晴好天气下新疆戈壁地区的 大气气溶胶光学厚度和波长指数数据进行统计分析,给出5种典型气溶胶光学厚度日变化类型。并对日均气溶 胶光学厚度进行月季变化特性分析,6～8月气溶胶光学厚度最小,达到0.1,而4月最大均值达到了0.73。 波长指数的分布和气溶胶光学厚度存在近似的反相关性,说明该地区的气溶胶光学厚度主要受沙尘 性气溶胶的平均粒径所影响。
Abstract
The inversion calculation method about aerosol optical depth(AOD) and Angstrom wavelength exponent was given by using the sun photometer CE318. The aerosol optical depth and wavelength exponent in Gobi area of Xinjiang were statistically analyzed and five kinds of typical daily variation model about aerosol optical depth were given. The characteristics of season variation about daily average were given, the minimum AOD in June to August is 0.1, and the maximum mean in April is 0.73. There is an inverse correlation about wavelength exponent and AOD. The AOD in Gobi area is influenced by the particle diameter of sand dust.
