The World Climate Research Programme(WCRP) estavlished in 2009 the Task Forxe for Regional Climate Downsaling(TFRCD), which created the CORDEX initiative to generate regional climate chage progextions for all terrestrial regions of the global withinn the timeline of the Fifth Assessment Report (AR5) and beyond.

The majar aims of the CORDEX initiative are to provide a coordinated model evaluation framework, a climate projection simulations in climate change impact, adaptation, and mitigation studies.

CORDEX-East Asia is the East-Asian branch of the CORDEX initiative and will produce ensemble climate simulations based on multiple dynamcal and statical downscaling models forced by multiple global climate models.
