TL;DR: The Earth system model EC-Earth3 for contributions to CMIP6 is documented in this paper , 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 historical period.

TL;DR: It is demonstrated here that EC-Earth3 is suited for a range of tasks in CMIP6 and beyond, and key performance metrics demonstrate physical behaviour and biases well within the frame known from recent CMIP models.

TL;DR: The Stratosphere-troposphere Processes And their Role in Climate (SPARC) Quasi-Biennial Oscillation initiative (QBOi) aims to improve the fidelity of tropical stratospheric variability in general circulation and Earth system models by conducting coordinated numerical experiments and analysis as discussed by the authors.

TL;DR: Large-scale diagnostics of the second major release of the ESMValTool tool, a community diagnostics and performance metrics tool designed to improve comprehensive and routine evaluation of Earth system models participating in the Coupled Model Intercomparison Project (CMIP), are described.

TL;DR: In this paper, the authors compare the performance of the model simulations of the amplitudes and phases of the SAO in zonal-mean zonal wind near the stratopause with the information derived from available observations.
