The Common Community Physics Package (CCPP) Framework v6

A primary goal for this effort is to facilitate research and development of physical parameterizations and experimentation with physics-dynamics coupling methods while simultaneously offering capabilities for use in numerical weather prediction (NWP) operations.

The CCPP Framework supports configurations ranging from process studies to operational NWP as it enables host models to assemble the parameterizations in flexible suites. Framework capabilities include variability in scheme call order; ability to group parameterizations for calls in different parts of the host model, allowing intervening computation or coupling to additional components; options to call some parameterizations more often than others; and automatic variable transformations.
