| 摘 要： | 根据我国渤海区域星载微波遥感ＤＭＳＰＳＳＭ／Ｉ１９９４～１９９６年的观察数据的研究，指出现有的星载微波遥感海冰的数据标定和验证ＴＢＩ和ＯＳＩ算法是不适用的。用２２和８５ＧＨｚ的散射指数ＳＩ和１９ＧＨｚ的极化指数ＰＩ，讨论了渤海区域海冰的主要辐射特征，用矢量辐射传输理论数值模拟了ＳＩ、ＰＩ与海冰覆盖及其厚度变化的定量关系，用ＳＩ－ＰＩ图规划了渤海区域性海冰的识别方法，给出了渤海海冰的空间分布及其辐射特征的时间序列变化。

| Abstract: | SSM/I data on the Bohai Sea of China from 1994 to 1996 have been studied. The sea ice algo- rithms of calibration/validation such as the brightness temperature indexAES/YORK TBI (Hollinger et al. , 1992 )] and ocean scattering index{OSI(Ferraro et al. , 1996 , The Bulletin of the American Meteorological Society. 77 (5), 891-905)]are not applicable to the detection of regional sea ice of mid-latitude Bohai Sea area. A method of the scattering index SI and polarization index PI to identify regional Bohai Sea ice is pre- sented. Numerical results of vector radiative transfer for a model a layer of sea ice over ocean simulate the re- lationship between SI/PI and sea ice depth,and others. It is employed to categorize the SI/PI indices for the detection of sea ice. |
