| 摘 要： | 以MODIS/TERRA卫星为数据源,以2006~2009年黄渤海区域五个台站的实况资料和部分海测资料为依据,选取了23幅有雾天气卫星云图为样本,对卫星36个通道进行了相关性分析实验,通过该实验实现了海雾特征通道的选择。对特征值与日地关系因子进行了相关性分析实验,讨论了日地关系因子对海雾特征值的影响,提出了特征通道特征值的订正方法。在此基础上,运用阈值法进行了海雾检测,取得了理想的海雾正检率。 |

| Abstract: | In this paper,the 23 foggy weather remote sensing images based on MODIS/TERRA satellite are chosen as the data source,on the basis of the 2006-2009's real-time data of five meteorological observatories located on the Yellow Sea and Bohai and some marine meteorological data.The correlation between 36 channels of MODIS is analyzed,and then 5 characteristic channels of sea fog are filtrated.The correlation between characteristic value and solar factors is analyzed.At the same time,the correct method is achieve... |
