| 摘 要： | 提出了一种新的处理漫射因子的拟合方案,通过与前人提出的方案相比,具有较高的拟合精度;然后,将该拟合方案和前人提出的方案同时放入辐射传输模式中来计算大气加热率,结果表明:新方案的结果总体上优于前人的结果,尤其是对45 km以上的中间层大气.

| Abstract: | In this paper, a new scheme, which is more precise in comparison with the previous ones in dealing with diffusivity factor is presented. The new scheme and the previous ones are applied to a radiative transfer model to calculate the atmospheric heating rate. The results show that the new scheme is generally better than previous ones, especially in the upper atmosphere al a height of more than 45 km. |
