Short summary

Future climate behavior is typically modeled using computer-based simulations, which are generated for both historical and future time periods. The trustworthiness of these models can be assessed by determining whether the simulated historical climate matches what was observed. We provide a tool that allows researchers to identify major differences between observed climate and climate model predictions, which will hopefully lead to further model refinements.
