Running an Experiment

The examples in the CCLM starter package are built in a way that everything will be stored under the directory tree starting with $SPDIR and therefore will be on the same file system. This is often not convenient, it might be better to put scripts and I/O to different more appropriate file systems. This could be done by setting the main directory settings (see table) in the job_settings script accordingly. 

Before you run your own experiment it is recommended to run the test cases sp001 and sp002 as described in the Install section.

Downscaling simulation with GCM data (gcm2icon)

Make a copy of the template sp001 as starting point for your experiment (this is named exp001 in the following, but you can use a name by yourself).

cp -R $SPDIR/chain/gcm2icon/sp001 yourpath/exp001

Change into the yourpath/exp001 directory and perform your changes in the job_settings file and the other scripts. Then perform a clean to get rid of any unnecessary files that may have transferred during the copying of sp001.

cd yourpath/exp001
./subchain clean

Now you are ready to start your experiment

./subchain start

If the simulation is successful you can find the output data under the directories $ARCHIVE_OUTDIR and as post-processed time series under $WORKDIR/exp001/post.

Nested simulation (icon2icon)

Make a copy of the template sp002 as starting point for your experiment (this is named exp002 in the following, but you can use a name by yourself).

cp -R $SPDIR/chain/gcm2icon/sp002 yourpath/exp002

Change into the yourpath/exp002 directory and perform your changes in the job_settings file and the other scripts. Then perform a clean to get rid of any unnecessary files that may have transferred during the copying of sp002.

cd yourpath/exp002
./subchain clean

Now you are ready to start your experiment

./subchain start

If the simulation is successful you can find the output data under the directories $ARCHIVE_OUTDIR and as post-processed time series under $WORKDIR/exp001/post.
