Abstract

We describe the first effort within the Coordinated Regional Climate Downscaling Experiment-Coordinated Output for Regional Evaluation, or CORDEX-CORE EXP-I. It consists of a set of twenty-first-century projections with two regional climate models (RCMs) downscaling three global climate model (GCM) simulations from the CMIP5 program, for two greenhouse gas concentration pathways (RCP8.5 and RCP2.6), over nine CORDEX domains at ~25-km grid spacing. Illustrative examples from the initial analysis of this ensemble are presented, covering a wide range of topics, such as added value of RCM nesting, extreme indices, tropical and extratropical storms, monsoons, ENSO, severe storm environments, emergence of change signals, and energy production. They show that the CORDEX-CORE EXP-I ensemble can provide downscaled information of unprecedented comprehensiveness to increase understanding of processes relevant for regional climate change and impacts, and to assess the added value of RCMs. The CORDEX-CORE EXP-I dataset, which will be incrementally augmented with new simulations, is intended to be a public resource available to the scientific and end-user communities for application to process studies, impacts on different socioeconomic sectors, and climate service activities. The future of the CORDEX-CORE initiative is also discussed.

The CORDEX-CORE data used in this work can be found at the Earth System Grid Federation (ESGF) databanks following the CORDEX output specifications. The CMIP5 data can be found at http://cmip- pcmdi.llnl.gov/cmip5/data_portal.html (CMIP5). The CORDEX-CORE ICTP simulations were carried out at the CINECA supercomputing center in Bologna, while the REMO simulations were performed under the GERICS/hereon share at the German Climate Computing Centre in Hamburg (DKRZ). We acknowledge DKRZ in Hamburg and CINECA in Bologna for providing the high-computing capacity, and the Earth System Grid Federation (ESGF) for hosting the CORDEX-CORE projections. We also acknowledge the World Climate Research Program Working Group on Coupled Modelling and all the modeling groups for computing and providing the CMIP5 simulations that were used as boundary forcing for the CORDEX-CORE experiments. Jason Evans was supported through funding from the Earth Systems and Climate Change Hub of the Australian Government's National Environmental Science Program. The authors also thank three reviewers for their useful comments, which helped to improve the quality of this paper.
