 There are many ways to visualize data produced by ICON-ART. In general, there are two possibilities: The output may exist on the ICON grid or it may exist on an interpolated longitude/latitude grid. This can be chosen by adaptions of the output namelist. Although it comes along with a loss in information, sometimes it is only possible to use interpolated output. By this, the visualization is much easier to handle.

	In the following sections some tools are introduced which can be used to visualize ICON output. Note, that '''only NETCDF''' is supported by ICON-ART so far. With the tool Ncview it is very easy to have a quick look into the interpolated model output. With ParaView and Met3D a nice-looking three-dimensional visualization can be created.

			=== Met3d ===

			Met3D is a visualization software that can be used on a HPC system to visualize ICON as well as ICON-ART data in 3D. An online documentation can be found [https://met3d.wavestoweather.de/met-3d.html here]. Met3D needs remapped ICON fields to Latitude-Longitude . Furthermore, it is important to have the pressure (pres - variable) as model output, as Met3D transforms model levels in pressure levels for plotting.
