中文摘要：

在以往云检测算法的基础上,利用MOD IS传感器高光谱和高时间分辨率的特点,建立一套针对MOD IS夜间影像的,以单、多时相组合方法为基础的夜间云检测算法。通过对我国南北地震构造带（南北带）影像进行云检测试验证实,该算法对MOD IS夜间影像上的各种云类具有较好的检测效果。

英文摘要：

Based on traditional cloud detection methods, the authors developed a new algorithm for detecting night cloud according to characteristics of MODIS sensors which have high spectral resolution and time resolution. The algorithm includes the single -scene cloud detection method and the combined multi -scene cloud detection method. The test of night cloud detection on the N- S seismotectonic zone in China shows that this algorithm is effective in detecting night cloud on the MODIS image, and thus it can provide a basis for the effective application of night MODIS image.
