摘要： 针对 MODIS 卫星数据的特点，基于 Streamer 大气辐射传输模式，通过模拟各种云类和陆地辐射雾在 MODIS 可见光、短波红外、中红外波段的光谱辐射特征，提出了一种基于归一化雾指数进行陆地辐射雾检测的特征参数，实验表明利用归一化雾指数特征参数能够较好地进行陆地辐射雾检测。

Abstract: A parameter named Normalized Difference Fog Index (NDFI) is proposed to detect land radiation fog based on analyzing the spectral character of fog and cloud in visible, short infrared and middle  infrared wave band by employing the Streamer radiative transfer model and the MODIS data. Threshold is set according to the histogram. It is demonstrated by two cases over mainland China in winter that this NDFI parameter could be applied to perform land radiance fog detection with high accuracy.
