摘要 为提高卫星反演云层光学厚度精度,提出了对渐近理论中半无限云体反射函数参数表达式进行透射率修正,得到了能够反映真实大气的反射函数理论值。使用这种方法对2004年5月12号欧空局SC IA-MACHY仪器通道4得到的氧气A带基线区域数据进行处理,尝试反演有代表性的海洋和亚热带区域云的光学厚度,得到较好的结果。证明了氧气A吸收带基线区域对于反演云光学厚度的应用具有一定的潜力。 To improve cloud optical thickness (COT) retrieval, the classic asymptotic theory was reviewed and a new modified express of transmission was used in reflection function of semi-infinite cloud, which would be more reasonable in real atmosphere. To retrieve cloud optical thickness in cloud optical oceanic and sub-tropic area the data from ESA-SCIAMACHY channel 4 (12 May 2004) was processed to get a statisfying result. The experiment proves that the oxygen A-band base line channel has potential in the future COT retrieval.
