Description

<p>To evaluate impacts of climate change on water environment and ecosystem services, Global Climate Models (GCMs) are used in the previous studies. However, it is necessary to apply bias correction to GCM with long-term observation data (e.g. over 20 years) to evaluate impacts of climate change since GCMs has biases between the observation data. In generally, reanalysis data has been used in a data scarce area. However, despite reanalysis data has been applied data assimilation method based on observation data, reanalysis data does not match the real weather characteristics (e.g. precipitation) in a local scale since it is targeted at a global scale. In previous studies, statistical correction method for precipitation of reanalysis data has been developed. However, the method has not been developed for hydro-meteorological data except for precipitation (e.g. temperature, air-pressure, windspeed). Therefore, this study aims to develop and apply the statistical correction method for hydro-meteorological data of re-analysis data.</p>
