CCPP SciDoc  v6.0.0
Common Community Physics Package Developed at DTC

Welcome to the scientific documentation for the parameterizations available in the Common Community Physics Package (CCPP) v6.0.0 and the suites that can be configured using them.

The CCPP-Physics (available through is envisioned to contain parameterizations used in the Unified Forecast System (UFS) applications for weather through seasonal prediction timescales, encompassing the current operational GFS schemes, as well as developmental schemes under consideration for upcoming operational implementations. The UFS can be configured for multiple applications, including the UFS Short-Range Weather (SRW) Application (available through, which targets predictions of atmospheric behavior on a limited spatial domain and on time scales from less than an hour out to several days, and the UFS Medium-Range Weather (MRW) Application (available through, which targets predictions of global atmospheric behavior out to about two weeks.

The CCPP parameterizations are aggregated in suites by the host models. In this release, the CCPP Single Column Model (SCM), developed by the Development Testbed Center (DTC), supports suites:

while the UFS Short-Range Weather Application 2.0 supports suites GFS_v16 Suite, HRRR Suite, RRFS_v1beta Suite and WoFS_v0 Suite.

New schemes and capability highlights in this release:

In this website you will find documentation on various aspects of each parameterization, including a high-level overview of its function, the input/output argument list, and a description of the algorithm. More details about this and other CCPP releases may be found on the CCPP website hosted by DTC.
