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.
