摘要
在分析雾、云、地表、水体等目标物红外辐射特性的基础上,针对MODIS数据提出了夜间雾监测算法。试验表明,该算法能够将低云大雾与中高云、水体和地表区分开。
Based on the analysis of the infrared radiation characteristics of different objects, the paper proposes the detection algorithm of nighttime fog on MODIS data, and the algorithm has been tested and analyzed. The result shows that the algorithm can distinguish preferably the nighttime fog from cloud, water and surface.
