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.
