In this Tutorial, the steps to simulate a Volcanic Eruption via a point source are given.
Setting up ICON-ART
The first thing to do is having a working installation of ICON-art. To check if your icon version has been built correctly, you can check if
your_icon_folder/bin/icon.exe
exists.
Setting up Directories
Now a directory structure has to be set up. Usually the following directories are used:
- Working Directory: Here the files that are needed for an individual run are saved. This usually includes the runscript and the relevant .xml files.
- Icon Code directory: This is where the Icon code is stored.
- External Data directory: Here external files which are needed for a run are stored. For example, to parametrize the optical properties of clouds a files like ECHAM6_CldOptProps.nc is used. These files of course can be switched out for others, however in most applications the same ones are used. A list of the used files is given in the Runscript, which then creates a link of these files in the Output directory.
- Output directory: This is where the new Simulation data will be stored. Since most of the time large amounts of data are produced, this is stored in the work or scratch partitions on most HPC Systems. The Namelists produced by the runfile are also stored here.
