AB: The Earth keeps its temperature balance by emission of energy through long-wave radiation while absorbing the shortwave radiation from the sun and getting warm. The cloud has enormous influence in radiation and heat budget. Cloud generation increases the planetary albedo of the earth , and the energy that the earth absorbs decreases. Terrestrial radiation is absorbed by the cloud, and radiated toward the surface level. The emission of energy to the space from the earth decreases, because it is replaced by lower temperature emission from the cloud. The effect of albedo is to cool the earth, and the effect of emission is to keep the earth warm. These effects have large radiative forcing with enormous influence on the energy balance of the earth. GMS-5 is a geostationary satellite enabling observations every hour. By using these observation data, high time resolution is attained in the estimation of the Earth's radiative budget. At first, the cloud optical thickness estimated from GMS-5/SVISSR data are compared with Terra/MODIS for data quality evaluation with in the APEX (Asian Atmospheric Particle Environment Change Experiment) project. And using the radiative transfer code "RSTAR5b" modified for radiative budget, we examined the influence of this error in the estimation of the radiative budget.
