摘　　要：在分析现有低云大雾识别方法的基础上,提出了利用夜间微光云图和红外云图识别低云大雾的双通道阈值法,并用美国国防气象卫星DMSP/OLS实测数据进行了验证。实验结果表明了基于DMSP/OLS数据的双通道阈值法进行夜间低云大雾监测的可行性。Based on the analysis of the existing methods of detecting low clouds and heavy fog,the multi-channel threshold algorithm for detecting the low clouds and heavy fog during nighttime was proposed by the use of a combination of VIS and IR images in this paper,and the result was further verified by using the DMSP/OLS data.The result proved the feasibility of the multi-channel threshold algorithm on the detection of low clouds and heavy fog during nighttime using DMSP/OLS data.
