Short summary
Climate simulation codes are especially complex, and their ongoing state of development requires frequent software quality assurance to both preserve code quality and instil model confidence. To formalize and simplify this previously subjective and expensive process, we have developed a new tool for evaluating climate consistency. The tool has proven its utility in detecting errors in software and hardware environments and providing rapid feedback to model developers.
