摘要：

气溶胶光学性质对于气候、环境以及卫星遥感具有重要意义。利用CE317太阳光度计定点观测了天津近岸2014年3~5月气溶胶光学数据，分析了渤海湾近岸地区春季气溶胶光学特性。结果表明：气溶胶光学厚度（aerosol optical depth , AOD）光谱基本满足Angstrom关系；AOD日变化基本有三种变化趋势：上升型、平稳型、下降型；春季440 nm波段AOD均值为0.776，Angstrom指数α均值为1.011，浑浊度系数β均值为0.344。将该结果与黄海近岸的青岛地区进行了比较分析，表明了气溶胶光学性质的区域性。

关键词: 气溶胶光学厚度, Angstrom指数, 浑浊度系数, 天津近岸

Abstract:

Aerosol optical properties are important for climate, environment and satellite remote sensing. The aerosol optical data of Tianjin coastal area from March to May in 2014 are measured by using the CE317 Solar Photometer, and further analyzed. The results show that aerosol optical depth (AOD) spectra are basically accord with Angstrom relationship. There are three basic types of AOD daily variations, which are rising type, stationary type and declining type. The mean value of 440 nm AOD in spring is 0.776, the Angstrom exponent α is 1.011, and the Angstrom turbidity coefficient β is 0.344. The results are compared with the Qingdao area in the Yellow Sea coastland, which shows the regional characteristics of aerosol optical properties.

Key words: aerosol optical depth, Angstrom exponent, turbidity coefficient, Tianjin coastland
