Research Abstract

The purpose of this research is to develop a simple yet efficient statistical downscaling (SDS) method to downscale 60-km AGCM output into 20-km resolution for the precipitation data. We has successfully developed a new technique of statistical downscaling considering the spatial correlation structure of precipitation. Here, the downscaling target is 60-km resolution of daily precipitation for 20-km resolution data, which is based on a downscaling window having (3x60-km)x(3x60-km) of area. The proposed regression model provides very effective and efficient results with a certain level of estimation error.
