! ---------------------------------------------
! This file is part of an effort to replace most uses of preprocessor CPP keys by fortran variables,
! to improve readability, compilation coverage, and linting.
! CPP keys used here should ONLY be used here (unless specified explicitely),
! and imported through USE ..., ONLY: ... elsewhere
! CPP keys supported (key -> fortran variables associated):
!      NC_DOUBLE -> nf90_format
!      CPP_PHYS  -> CPPKEY_PHYS
!      INCA      -> CPPKEY_INCA
!      CPP_StratAer-> CPPKEY_STRATAER
!      CPP_DUST  -> CPPKEY_DUST
