Common Community Physics Package (CCPP)

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

The Global Model Test Bed (GMTB) has been tasked to develop a Common Community PhysicsPackage (CCPP) for use within operational centers and the research community. Such a framework allows for a relatively small number of supported suites of physical parameterizations to be supported and easily shared among interested groups. Operational centers can draw from this repository for operational NWP, the research community has access to the same codes for R&D, and innovations can be effectively tested and funneled back to operational centers to improve forecasts.
