The Common Community Physics Package: Recent Updates and New Frontiers

In the last year, the Common Community Physics Package (CCPP) saw its first transition to operations, as part of the NOAA Hurricane Analysis and Forecast System (HAFS) v1. This is an important landmark for the CCPP, which has been adopted as a cornerstone of the Unified Forecast System (UFS) and is on track to be used in all the upcoming implementations of NOAA global and limited-area Earth System prediction models. Reaching this level of maturity has been possible due to numerous community contributions to enhance the parameterizations in the CCPP Physics and due to stable and efficient computational performance of the CCPP Framework. These contributions have been facilitated by the use of the CCPP Single-Column Model for hierarchical experimentation and testing.

In this presentation we will cover the updates made to the CCPP in the last year, review the ongoing development, and discuss the outcomes of the CCPP Visioning Workshop in August 2023. The latter was a multi-institutional event intended to inform the community about the CCPP and to gather input on a range of subjects. Topics covered include code management, releases, documentation, support, and best practices for interoperability to foster collaborative development. Plans for chemistry and atmospheric composition interfaces, and their relationship to the CCPP, were also discussed.
