Depiction of the concept of a Common Community Physics Package Ecosystem. Although an officially-supported version of the CCPP exists (within bold-outlined oval), the software infrastructure allows for use (largest oval) and development (second-largest oval) from within the broader community. The operational physics suite can be drawn from the supported CCPP
