Coordinated Regional Climate Downscaling Experiment (CORDEX)
• Why downscaling?
– IAV communities’ demand for high resolution climate information.
– GCMs are not enough to resolve local features and their extremes.

Summary
• Preliminary results from the CMIP5 experiments based on new RCP scenarios– Information on global land cover change applied– Using HadGEM2-AO (collaboration with UKMO Hadley Centre)– In general, the results is similar to the CMIP3 experiment– New information from model improvements, such as river discharge,
etc. – CORDEX regional experiment underway– Data size ~ 2 PB for global & regional data (Korea only)
• Need further analysis using multi-model ensemble from CMIP5 to assess the range of global and regional climate projection
• Need further model improvement, such as cloud, carbon cycle, dynamic vegetation, dynamic ice melting, resolution, etc., to understand the response of the global climate system under future scenario higher computing power, data storage
• Better regional climate projection for better impact and vulnerability assessment on regional/national scales
