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. []. The Atmospheric component of the model is now available for use on Raijin.
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 ...
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
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`
