As part of the Coupled Model Intercomparison Project (CMIP) organized under the auspices of the World Climate Research Programme’s (WCRP) Working Group on Coupled Modelling (WGCM) many hundreds of climate researchers, working with modeling centres around the world, will share, compare and analyze the latest outcomes of global climate models. These model products will fuel climate research for the next 5 to 10 years, while its careful analysis will form the basis for future climate assessments and negotiations. The sixth phase of CMIP (CMIP6) is now underway with the WCRP Grand Science Challenges as its scientific backdrop. The DLR Institute of Atmospheric Physics (IPA) will contribute to CMIP6 by running the ESMValTool routinely on model output submitted to the CMIP archive for a more systematic, open and rapid performance assessment of the large and diverse number of models. This will also expose whether long-standing model errors remain evident in newer models and will assist modelling groups in improving their models. The Institute of Atmospheric Physics will also participate in CMIP6 by contributing simulations with the EMAC model.
CMIP started twenty years ago as a comparison of a handful of early global coupled climate models. In response to a growing need to systematically analyze coupled ocean and atmosphere model outputs from multiple climate modeling centres, it has subsequently grown into a large program to advance model development and scientific understanding of the Earth system. To meet these new goals, CMIP has developed well-defined climate model experiment protocols, formats, standards, and distribution mechanisms to ensure model output availability to a wide research community.
