Abstract

The Earth system model EC-Earth3 for contribu- tions to CMIP6 is documented here, with its flexible coupling framework, major model configurations, a methodology for ensuring the simulations are comparable across different high-performance computing (HPC) systems, and with the physical performance of base configurations over the histor- ical period. The variety of possible configurations and sub- models reflects the broad interests in the EC-Earth commu- nity. EC-Earth3 key performance metrics demonstrate phys- ical behavior and biases well within the frame known from recent CMIP models. With improved physical and dynamic features, new Earth system model (ESM) components, com- munity tools, and largely improved physical performance compared to the CMIP5 version, EC-Earth3 represents a clear step forward for the only European community ESM. We demonstrate here that EC-Earth3 is suited for a range of tasks in CMIP6 and beyond.
