Software Release: GMTB public release of CCPP v2.0

The DTC’s Global Model Test Bed (GMTB) is pleased to announce the public release of the Common Community Physics Package (CCPP) v2.0, containing a library of physical parameterizations (CCPP-Physics), and the framework that connects it to host models (CCPP-Framework). In this release, the CCPP has been bundled with the GMTB Single Column Model (SCM) v2.1, and contains updated physical parameterizations of the GFS suite plus the GFDL microphysics scheme.

The CCPP has also been integrated with the experimental version of NCEPs’ Global Forecast System (GFS) that employs the Finite-Volume in the Cubed-Sphere dynamical core (FV3). This capability is under review and is not supported as part of the public release. Interested developers should contact GMTB for access.
