Short summary
The Community Earth System Model Ensemble Consistency Test (CESM-ECT) suite was developed as an alternative to requiring bitwise identical output for quality assurance. We extend the CESM-ECT suite with an inexpensive and robust test for ensemble consistency that is applied to Community Atmospheric Model output after only nine model time steps. The new ultra-fast test facilitates CESM development, porting, and optimization efforts, and complements the original suite of tools.
