| 摘 要： | 在天空亮度分布中，大气散射方向指数占有非常重要的地位，以往的研究忽 大气混浊度因子对散射方向指数的影响。本文在散射方向指数中考虑大气混浊度因子的影响，。提出了新的大气散射方向指数函数，对不同的混浊度因子，此函数与已 知的晴天，部分云天和似阴天空有较好的近似，并更全面地考虑了分子散射，对进一步研究中间天空亮度分布具有理论意义。

| Abstract: | Atmospheric scattering directional exponetional function is very important to study of the distribution of skies luminance.The influence of air turbidity factor to atmospheric scattering directional exponetional function was neglected previously.In this paper,influence of air turbidity factor on atmospheric scattering was considered and a scattering function,which proximates clear,cloudy and pseud-overcast by varied turbidity factors,was presented.The atmospheric scattering for varied air condition was considered and molecular scattering was included in the function.Hence it provides a path for further theoretical study on sky luminance distribution. |
