| 摘 要： | 根据云雾及下垫面在可见光、长波红外和中红外波段的反射及辐射特性差异，结合MODIS资料，得出不同的波谱廓线并进行波谱分析。利用分析结果给出多通道综合阈值法监测大雾的流程，并用此方法进行了个例分析。结果表明：MODIS资料在雾监测方面有很好的应用潜力；中红外通道在雾监测上有独特的优势。

| Abstract: | According to the differences of the reflection and radiation characteristics of cloud/fog and underlying surface in VIS and IR,various spectral profiles from MODIS data are analyzed.Based on the analysis results,a flow chart of fog-monitoring using the multi-spectral synthesis method is given and the fogs which occurred at 13:30 on December 13,2004 in North China Plain as well as at 14:15 on December 14,2004 in Sichuan Basin are detected.The result shows that MODIS data has great potential in fog detection,especially the mid-infrared band has great predominance in fog-monitoring. |
