The Conformal Cubic Atmospheric Model (CCAM) is a global stretched grid climate model used for weather and climate research. CCAM is typically used for downscaling General Circulation Models for regional projections and tailored weather forecasting. CCAM's variable resolution grid can be multiply nested for downscaling without lateral boundaries. The model also supports various Earth system components including an implicitly coupled ocean model, prognostic aerosols and terrestial carbon cycle.

CCAM requires the NetCDF and Message Passing Interface (MPI) libraries. Although CCAM is written in fortran, it links with the NetCDF C library.
To build CCAM with the Intel (default), Nvidia, GNU or Cray fortran compiler use the corresponding build option below
make
make NVIDIA=yes
make GFORTRAN=yes
make CRAY=yes
CCAM also has limited support for GPUs, which can be enabled with
make GPU=yes
Debugging is also enabled with
make TEST=yes
