Paper Abstract

Estimation of solar radiation is very important basic research which can be used in solar energy resources estimation, prediction of crop yields, resource-related decision-making and so on. Accordingly, recently diverse researches for estimating solar radiation are performing in Korea. 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 Heliosat-II method is optimized for estimating solar radiation of Europe. Basically Heliosat-II method estimate solar radiation by using Meteosat meteorological satellite imagery and statistical data which are taken around Europe. Because these data do not include Korea, Heliosat-II method must be modified for using in estimation solar radiation of Korea. So purpose of this study is Heliosat-II modification for irradiance estimation by using image of COMS-M, weather satellite of Korea. For this purpose, in this study, error if albedo was removed in ground albedo image which was made by using apparent albedo and atmosphere reflectance. And method of producing background albedo map which is used in Heliosat-II method is modified for getting more delicate one. Through the study, ground albedo correction could be successfully performed and background albedo maps could be successfully derived.
