摘要
针对近年来利用卫星可见和红外波段遥感数据反演云顶高度的算法,对国内外研究进展和存在的问题进行综述。首先,主要介绍以红外窗区和CO_2吸收技术为主的红外波段反演算法;在此基础上,进一步介绍目前相关国家和地区的业务算法,对这些方法在实际应用中的优缺点予以评述,提出针对中国地区云顶高度反演的解决方案。将来,有发展前途的方法为基于红外分裂窗的查算表法,利用静止卫星的分裂窗数据及极轨卫星云廓线雷达数据,建立基于分裂窗亮温差和11μm通道亮温的云顶高度查算表,根据分裂窗亮温差和11μm亮温查表得到云顶高度。
According to recent years cloud top-height inversion algorithms using satellite visible and infrared remote sensing data,domestic and foreign algorithm research progress and problems are summarized.Through th analysis of large number of related literatures,the inversion algorithms of the infrared window methods and CO2absorption technique are mainly introduced.On the basis of these algorithms,the current business algorithms in countries and regions are expressed.Then the advantages and disadvantages of these methods in application are reviewed,and the cloud top-height inversion solution for regions in China is present.In the future,the method of cloud top-height lookup tables based on infrared split-window is prospective.In application and research,lookup tables based on brightness temperature difference and11μm channel brightness temperature are constructed using split-window data of stationary satellite and cloud profile radar data of polar orbit satellite,and cloud top-height can be acquired by checking lookup tables by split-window brightness temperature difference and11μm channel brightness temperature in application.
