What files are what

The top level directory structure groups source code and input files as follow:

File/directory Purpose
LICENSE.md A copy of the GNU Lesser General Public License, Version 3.
README.md This file with basic pointers to more information.
AQM/ Contains air quality modeling component
CMEPS-interface/ Contains CMEPS mediator
CICE-interface/ Contains CICE sea-ice model component including CICE6 and Icepack
CDEPS-interface/ Contains CDEPS data components, including data-atmosphere (DATM) and data-ocean (DOCN) model components
FV3/ Contains FV3 atmosphere model component including FV3 dynamical core, dynamics to physics driver, physics and IO.
GOCART/ Contains GOCART aerosol model component
HYCOM-interface/ Contains HYCOM ocean model component
MOM6-interface/ Contains MOM6 ocean model component
NOAHMP-interface/ Contains Noah-MP land model component
WW3/ Contains community wave modeling framework WW3
stochastic_physics/ Contains the stochastic physics source code
cmake/ Contains compile option files on various platforms.
modulefiles/ Contains module files on various platforms.
tests/ Regression and unit testing framework scripts.
build.sh | Script to build the model executable (also used by tests/)

E.g. use of build.sh to build the coupled model with FV3_GFS_v15p2 as the CCPP suite.

$> CMAKE_FLAGS="-DAPP=S2S" CCPP_SUITES="FV3_GFS_v15p2" ./build.sh

The build system is regularly tested with Tier-1 and Tier-2 platforms. Configurations for other platforms that are available with UFS should be used with the understanding that they are not regularly tested and users will have to adapt those to make it work.
