The NCEP is continuously evolving its production suite to advance its predictive skill. One of the focus areas for improvement is physical parameterizations and, to that end, the NOAA Next-Generation Global Prediction System program has funded the creation of a Common Community Physics Package (CCPP), a collection of parameterizations within a framework that supports straightforward addition of new schemes and connection to various dynamic cores. Candidate dynamical cores include WRF-ARW, MPAS, and the Finite-Volume Cubed Sphere (FV3). The CCPP can also be used with the Global Model Test Bed Single-Column Model.

The CCPP promotes an agile environment for physics development and transition of research to operations as it can support a variety of users, including those interested in downloading the code to run experiments, scientists aiming at contributing new development, and operational centers that want to use the CCPP as a pool of innovations. Supported physics suites within the CCPP are vetted through rigorous assessment, while non-supported physics schemes must only conform to the software interface requirements. In this presentation we will describe the infrastructure and governance of the CCPP and provide an update on the status of physics suites available in the CCPP.
