The SCM can be built by following the instructions described OpenIFS 48r1 GettingStarted - Build OpenIFS. As described, these instructions will build, by default, both the OpenIFS executables for a 3D global simulation and the SCM executables. This step will also run a standard test to check that the SCM will run on the chosen system

Running the SCM

Before the SCM can be run, it is necessary to obtain and extract the SCM test-case package. In a similar fashion to the OpenIFS package and the experiment data, the SCM test-case package can be download from https://sites.ecmwf.int/openifs/openifs-data/scm/48r1/scm_openifs_48r1.1.tar.gz. Please note that access to this web site is restricted to registered OpenIFS users, i.e. your personal ECMWF account must have been added to the OpenIFS user policy.

In the example below we assume that the SCM package shall be installed in the user's HOME directory, and that the wget utility is available for convenient download: 

cd $HOME
wget https://sites.ecmwf.int/openifs/openifs-data/scm/48r1/scm_openifs_48r1.1.tar.gz
tar -xvzf scm_openifs_48r1.tar.gz
