提出了一种利用直接和漫射太阳辐照度以及光环通过改进的模拟退火来估计气溶胶的折射率和尺寸分布的方法。所提出的方法基于模拟退火，并通过使用逐渐减小的退火温度振荡函数来加速学习过程。利用Gauss Seidel模型，通过实验数据的经验方法，生成太阳直射辐照度和漫射太阳辐照度的模拟数据以及估计的光环。 P. Romanov 等人提出的现有方法的比较。等人。基于线性化反演方法提出了该方法。结果表明，气溶胶尺寸分布和折射率的估计精度提高了一倍和三倍。
An estimation method for refractive index and size distribution of aerosol using direct and diffuse solar irradiance as well as aureole by means of a modified simulated annealing is proposed. The proposed method is based on simulated annealing modified to acceralate a learning process by using a gradually decreasing oscillation function of temperature of annealing. By using Gauss Seidel model, simulation data of direct and diffuse solar irradiance are generated together with estimated aureole by means of empirical method with experimental data. A comparison between the existing method proposed by P. Romanov et. al. based on linearized inversion method and the proposed method is made. The results show double and tripple improvement of the estimation accuracy for both of aerosol size distribution and refractive index.
