| 摘 要： | 提出了一种利用中分辨率成像光谱仪热红外窗区通道数据进行云、晴空分离的新方法。该云检测算法从热红外窗区通道亮温出发，并结合水汽廓线，运用水汽规度法计算规度因子的值，利用规度因子的数值状态实现分离云和晴空，从而达到云检测的目的。经过大量的实验，并将结果与中分辨率成像光谱仪官方云检测产品作对比分析，结果表明准确率为91％，算法具有可行性。

| Abstract: | This paper presents a new method to discriminate cloud from clear scene utilizing MODIS infrared bands data. Integrating Water vapor profiles and infrared brightness temperature, the water-vapor scaling factor values have been calculated using the Water Vapor Scaling （WVS） method. Cloud processing result was found out to cloud from clear-sky based on the state of computational scaling factor values. Compared with the MODIS cloud mask product, the same probability is 91%, which indicates that the proposed algorithm is able to provide an accurate estimation of cloud detection from MODIS data. |
