Abstract
Irradiance estimation model's accuracy is sensitive to regions and climates. Especially, cloud is one of the greatest factor for ensure accuracy of solar irradiance estimation. So, cloud index which specified to particular region and imagery is important to estimation of solar irradiance over particular region. Heliosat-II method is one of the widely used model to estimate solar irradiance, and it's accuracy has been demonstrated by many other studies. But Heliosat-II method cannot be applied directly for estimate solar irradiance around korea. Because basically Heliosat-II method estimate solar irradiance by using Meteosat meteorological satellite imagery which is taken around Europe. In this study, we adjusts Heliosat-II method to the image of COMS MI, regular weather satellite of Korea, and manufactures a more delicate background map by using modified SSG method for making cloud index. As a results, we were able to make background map which is reflected current weather condition. And we were able to make cloud index image in Korea. And it will be used in completing whole heliosat-II method which is used to estimate irradiance in Korea.
