摘要提出了前峰散射与太阳天顶角和单次散射反照率有关的假设。计算表明，这种假设可以提高δ-Eddington近似的精度。对于散射保守的情况，该方法可以改善薄光学深度区域的结果。对于散射非保守情况，该方法可以减小入射太阳能量最显著的小天顶角区域的反射和吸收误差。
Abstract A hypothesis that the fractional scattering into the forward peak is related to solar zenith angle and single scattering albedo is proposed. Calculations show that this assumption can increase the accuracy of the δ-Eddington approximation. For the scattering conservative case this method can improve the results in the region of thin optical depth. For the scattering nonconservative case this method can reduce the errors for reflection and absorption in the region of small solar zenith angle, where the incoming solar energy is most significant.
