基于MODIS卫星数据的平流雾检测研究

Fog Detection Based on EOS MODIS Data

  • 摘要: 利用MODIS卫星数据,对雾与目标物(水、云、雪、地物)分别进行采样,得到光谱曲线并进行光谱分 析,提出了有利于白天和夜间平流雾检测的波段,利用该波段选择结果,采用阈值法对平流雾进行检测并得到 地面数据验证。结果表明,MODIS数据在雾检测方面具有很大的潜力。

     

    Abstract: Based on spectral profiles sampling from EOS MODIS data, the spectral characteristics of water, cloud, snow, surface features and fog are analyzed; Channels suitable for fog detection are discovered. On the basis of this, the advection fog, which occurred at 13:21 on Jan.5, 2004 and at 01:27 on Jan.6, 2004, in Liaoning Province and Liaodong Gulf, is detected. Validated from ground truth data, the result shows that MODIS data has great potential in fog detection.
