| 摘 要： | 该文简要介绍了遥感气溶胶光学厚度的宽带消光法, 重点比较与分析了2001～2002年间北京地区宽带消光法和全球气溶胶探测网(AERONET)气溶胶光学厚度的探测结果.对比结果表明, 两类探测结果在无云晴天的条件下具有很好的吻合, 二者的相关系数达到90%以上.另外, 作者还针对宽带消光法反演月平均气溶胶光学厚度问题, 提出了一个减小云对反演结果影响的方法, 即月平均光学厚度约束法, 并与全球气溶胶探测网探测结果做对比分析.二者结果的一致性表明该约束方法的有效性.

| Abstract: | The broadband extinction method for retrieving aerosol optical depth is introduced. Aerosol optical depths derived from the broadband extinction method and aerosol robotic network observation during 20012002 are compared and analyzed. The comparison results show that two kinds of detection are in good agreement in fine days and the relative coefficients exceed 90%. Furthermore, in order to solve the problem of cloud contamination in retrieving monthly-average aerosol optical depth from broadband extinction method, a method to minimize the cloud effects known as monthly-average aerosol optical depth restriction method is proposed, and the comparison with aerosol robotic network observation shows the feasibility of this method. |
