Polar-CORDEX (Coordinated Regional Downscaling Experiment - Arctic and Antarctic Domains) is part of the international CORDEX initiative.
CORDEX is a WCRP-sponsored program to organize an international coordinated framework to produce an improved generation of regional climate change projections for input into impact and adaptation studies. The Polar CORDEX activities are coordinated through CliC.
Currently, the core of Polar-CORDEX consists of regional climate model simulations over the Arctic, with hindcast (ERA-Interim and GCM-driven historical simulations) and scenario (GCM-driven rcp4.5, rcp8.5 simulations) simulations are conducted. For an overview of Arctic CORDEX activities go to: activities/targeted/polar-cordex/arctic. This effort is now expanding to include the Antarctic region as well.
