Description
Biases in model simulations of present-day climate do not only affect confidence in the capability of the models to correctly reproduce current climate but also raise concerns about the accurate representation future climate change. In this study we investigate the performance of state-of-the-art global climate models from the sixth phase of the Coupled Model Intercomparison Project (CMIP6) by comparing simulated water vapor and cloud properties with satellite observations. A focus is the variability of water vapor on seasonal and interannual time scales. The analysis is performed with the Earth System Model Evaluation Tool (ESMValTool), a community diagnostic and performance metrics tool for the evaluation of Earth System Models.
