An estimation of the clear sky irradiance is a crucial part of satellite based methods because it is employed to calculate the clear sky index. Although the accuracy of the clear sky irradiance depends on the AOD (Aerosol Optical Depth) and TPW (Total Precipitable Water) mixing ratio, data are difficult to acquire in real time. The Linke turbidity factor simplifies the data as a unique parameter that describes the attenuation of solar radiation in terms of a clean and dry atmosphere. SoDa provides the Linke turbidity maps all over the world, but those maps have low spatial and temporal resolutions. To estimate the clear sky irradiance over the Korean Peninsula using satellite images, this paper presents a method to estimate the Linke turbidity factor using COMS MI, which is operated by the Korea Meteorological Administration, and the clear sky irradiance using the ESRA clear sky model. The AOD and the TPW derived from COMS MI were also used to calculate the Linke turbidity. Overall, the results show that the Linke turbidity factor calculated from COMS MI has higher accuracy than that calculated using the SoDa data.
