The Model for Prediction Across Scales (MPAS) is a collaborative project for developing atmosphere, ocean and other earth-system simulation components for use in climate, regional climate and weather studies. http://mpas-dev.github.io/. The Atmospheric component of the model is now available for use on Raijin.

Building


Pre-built Module

A pre-built version of MPAS is available in the ACCESS modules:
module use ~access/modules
module load mpas/5.0

Once the module is loaded the data files are located in the directory $MPAS_DATA:
$ ls $MPAS_DATA
CAM_ABS_DATA.DBL
CAM_AEROPT_DATA.DBL
GENPARM.TBL
LANDUSE.TBL
...

Building MPAS

ARCCSS CMS maintains a branch of MPAS at https://github.com/coecms/MPAS-Release. This branch has some minor changes required to build the model on Raijin. To set up the build environment:
$ git clone https://github.com/coecms/MPAS-Release
$ cd MPAS-Release
$ source environment.raijin

You can then build individual cores with e.g. make ifort CORE=atmosphere, see the User's Guide for full details

Running


See the User's Guide for details on how to run the model. A number of idealised test cases as well as meshes for different resolutions are available from the MPAS download site. The $MPAS_DATA directory has all of the TBL, DBL and namelist files required to run MPAS
cp $MPAS_DATA myrun
cd myrun
# Edit configuration then qsub `run-atmosphere.pbs`
