The EC-Earth3 Earth system model for the Coupled Model Intercomparison Project 6

[摘要] The Earth system model EC-Earth3 for contributions toCMIP6 is documented here, with its flexible coupling framework, major modelconfigurations, a methodology for ensuring the simulations are comparableacross different high-performance computing (HPC) systems, and with the physical performance of baseconfigurations over the historical period. The variety of possibleconfigurations and sub-models reflects the broad interests in the EC-Earthcommunity. EC-Earth3 key performance metrics demonstrate physical behaviorand biases well within the frame known from recent CMIP models. Withimproved physical and dynamic features, new Earth system model (ESM) components, community tools,and largely improved physical performance compared to the CMIP5 version,EC-Earth3 represents a clear step forward for the only European communityESM. We demonstrate here that EC-Earth3 is suited for a range of tasks inCMIP6 and beyond.
