Mean Climate

Mean state results from the PCMDI Metrics Package (PMP) are used to produce “quick-look” summary diagrams for the CMIP multi-model ensemble. The focus is on the “Historical” (coupled) and “AMIP” (atmospheric only) simulations which are well-suited for comparing with observations. We update these summaries regularly as new simulations are contributed to CMIP6, quality-control and presentation are improved, and observational datasets are updated. We provide two methods to interactively explore these quick-look results, one as absolute errors and another as relative errors:
