根据光的多次散射理论——离散纵标法，利用我国国家一级辐射测站的大气廓线，计算出晴空大气观测波段不同高度上的太阳直接辐射和向下散射辐射。将模式输出的地面辐射值与地面辐射观测资料进行比较，对不同高度的太阳直接辐射和向下散射辐射以及日变化进行了讨论。最终目的是直接由MODTRAN 3计算我国辐射空白站的地面辐射值，以弥补我国辐射站稀少，时空分布短缺的不足。

Direct and defuse solar radiations at different heights for clear sky over China have been computed from atmospheric profiles with discrete-ordinate method based on the multiple scattering theory. The computed solar radiation at ground are compared with the ground observations obtained at a few national stations of first class. Computed results at heights and the daily variations are also discussed. The purpose of this research is to show that the software,MODTRAN 3,can be directly used to estimate solar radiation parameters for the places short of direct observations.
