NCAR CCPP-enabled Atmospheric Physics

Physics packages which are CCPP_enabled (along with supporting routines) are stored in this repository.

Physics schemes contain two files, a .F90 file which contains the routines and a .meta file which contains the CCPP metadata.
Standard names for metadata can be found here
Physics modules may contain one or more of the following routines (where XXX is the name of the module containing the physics)
- XXX_init - contains the startup/restart initialization required for the package. This is unthreaded and may contain I/O of undistibuted data (e.g. parameter tables)
- XXX_timestep_init - contains the initialization required for each timestep. This is unthreaded and may contain I/O of undistibuted data (e.g. parameter tables)
- XXX_run - the code which is run every timestep. Threading is controlled via the host model and the number of available threads will be passed into the routine. No I/O is permitted in this routine
- XXX_timestep_final - contains any post timestep handling. This is unthreaded
- XXX_final - contains any code logic which needs to be performed at the end of the run prior to the program exiting. This is unthreaded.
