Software Release: Release of the Common Community Physics Package (CCPP)

A Library of Physical Parameterizations for Atmospheric Numerical Models

The DTC’s Global Model Test Bed (GMTB) is pleased to announce the public release of the Common Community Physics Package (CCPP), a library of physical parameterizations for atmospheric numerical models. It is distributed with a framework that enables its use with any host application for which an interface is written. In this release, the CCPP has been bundled with the GMTB Single Column Model (SCM) and contains all the physical parameterizations used in the current operational NOAA Global Forecast System (GFS).

For more information, and to learn how to download, build, run, and contribute to the code, please visit the CCPP release page at Questions and comments can be directed to
