NOAA—AVHRR图像大气影响校正方法研究及软件研制第二部分:软件研制
A Researth on the Method and Computer program of Correction of Atmospheric Effects on NOAA-AVHRR Image Part 2:Programming
【摘要】 本文重点介绍平面平行大气多次散射方程的求解及Tovs资料与图像的配准等问题。对于散射方程的求解本文吸取了众多的研究成果,但由于我们已知的是大气顶的辐射,而未知的是地表反射率,因此直接利用正演方法将存在问题。为此,本文引进地面总波谱辐射与直接波谱辐射的比值作为中间变量,并提出了一种有效的解决办法。本文将重点介绍程序设计,并对一些结果进行了讨论,指出了进一步的工作。经过一年多的试运行,证明该软件运行可靠,时效较高,已达到常规运行的要求。
【Abstract】 This paper is the second part of“Correction of the effects of atmo-sphere on NOAA-AVHRR image”.In the first part,we have introduced the princi-ple and model.In this part,we will introdece the method for solving multiscatte-ring equation and the match between TOVS data and AVHRR image. About the sol-ving of multiscattering equation,we have absorbed many research result,but,becausewe have known the radiation at the top of atmosphere and the reflectance of the sur-face is unknown,so it is difficult to use the foreword calculation method.To solvethis problem,a variable of ratio between total radiance and direct radiance has beenintroduced and a efficacious method has been proposed.In chapter 3 of this paperwe will discuss the program and in chapter 4 some experiment results will be ana-lysed and some future work which may be important will be proposed.After morethan one year’s experiment,it is proved that the program is dependable and efficientand can be used routinly.
