-The Common Community Physics Package (CCPP), described `here <https://dtcenter.org/software-tools/common-community-physics-package-ccpp>`_, supports interoperable atmospheric physics and land surface model options. Atmospheric physics are a set of numerical methods describing small-scale processes such as clouds, turbulence, radiation, and their interactions. The most recent SRW App release (|latestr|) included six supported physics suites: FV3_GFS_v16, FV3_WoFS_v0, FV3_HRRR, FV3_HRRR_gf, RRFS_sas, and FV3_RAP. The FV3_GFS_v16 is an updated version of the physics suite used in the operational Global Forecast System (GFS) v16. A detailed list of CCPP updates made ahead of the SRW App v3.0.0 release is available :ref:`here <CCPPUpdates>`. A full scientific description of CCPP parameterizations and suites can be found in the `CCPP Scientific Documentation <https://dtcenter.ucar.edu/GMTB/UFS_SRW_App_v3.0.0/sci_doc/index.html>`_, and CCPP technical aspects are described in the :doc:`CCPP Technical Documentation <ccpp-techdoc:index>`. The model namelist has many settings beyond the physics options that can optimize various aspects of the model for use with each of the supported suites. Additional information on Stochastic Physics options is available :doc:`here <stochphys:index>`.
