基于MODIS的黄海海雾研究——海雾特征量反演

The Research on Yellow Sea Sea Fog Based on MODIS Data:Sea Fog Properties Retrieval and Spatial-Temporal Distribution

基于MODIS卫星数据,运用卫星遥感基本理论,提取了海雾、晴空海面、高云等不同类型信息进行统计研究,结合前人经验,确定了雾区反演和特征量反演的方法。对2007年5月4日上午一次黄海海雾过程的进行了反演,得到了定量的光学厚度、液态水路径、有效半径、雾顶高度和能见度等特征量,并用沿海观测站的探空数据以及船舶资料,对用卫星资料反演的雾顶高度和能见度进行了验证,效果比较理想。

Retrieval of the sea fog at Yellow sea in 4th May 2007 which is based on the EOS/MODIS data is presented.According to this calculation,the optical thickness,liquid water path,effective radius,height of fog top,and visibility are obtained.The sounding observations from stations and ship are matched up to this calculation.
