PURPOSE: A method for selecting the location of a wind farm is provided to calculate/reflect the optical thickness, property, and amount of atmospheric aerosols, thereby selecting the location in which the effects of air pollutants and yellow dust included in the atmospheric aerosols are minimized. CONSTITUTION: An aerosol model as an atmospheric model is set, and the atmospheric radiance data of a candidate area observed in an artificial satellite is received (S1100). Atmospheric reflectance is calculated from the atmospheric radiance data by using a radiative transfer equation, and the aerosol optical thickness of the candidate area is calculated by comparing the atmospheric reflectance with the aerosol model (S1200). By using the aerosol optical thickness and an extinction coefficient, the distribution of the air pollutants of the candidate area is calculated (S1400).
