| 摘 要： | 在可见光谱区 ,云的反射函数主要依赖于云的光学厚度 ;在近红外和中红外光谱区 ,云的反射函数主要依赖于云滴有效半径。根据上述原理 ,我们开发了一个利用NOAA AVHRR观测资料同时反演云的光学厚度和云滴有效半径的迭代方案。将该方案用于分析中国东海上空冬季层积云的辐射特性 ,取得了较为合理的结果。 |
| 关 键 词： | 云的光学厚度 云滴有效半径 卫星遥感 |

| Abstract: | In the visible spectral region, cloud reflection function depends mainly on the cloud optical thickness. In the near infrared and middle infrared spectral region, the cloud reflection function depends mainly on the cloud particle effective radius. Based on this consideration, we developed an iterative algorithm for the retrieval of cloud properties from NOAA-AVHRR imagery. The algorithm was applied to analyze the radiative properties of stratocumulus over East China Sea. The results indicated that the iterative algorithm has a reasonable accuracy. |
| Keywords: | cloud optical thickness effective radius satellite remote sensing |
