一个算法的伽玛加权离散纵标双流近似计算的配置文件的域平均短波辐射水平不均匀的多云大气。该算法假定云光学厚度在未分辨尺度上的频率分布可以用伽玛分布来表示，尽管它忽略了辐射的净水平输送。该算法是采用加法的早期研究中使用的算法的替代方案。目前，只允许阴天多云层。
An algorithm is developed for the gamma-weighted discrete ordinate two-stream approximation that computes profiles of domain-averaged shortwave irradiances for horizontally inhomogeneous cloudy atmospheres. The algorithm assumes that frequency distributions of cloud optical depth at unresolved scales can be represented by a gamma distribution though it neglects net horizontal transport of radiation. This algorithm is an alternative to the one used in earlier studies that adopted the adding method. At present, only overcast cloudy layers are permitted.
