2D and 3D visualization with Paraview

You can load ICON Data directly into the 3D Visualization software paraview using the CDI reader. Paraview allows for interactive visualization, and also has a python interface for scripting. It cannot handle things like lat/lon labels at the margins of your plot for publications.

On Mistral, you will need to use one of the GPU/Visualization nodes as described in https://www.dkrz.de/up/services/analysis/visualization/visualization-on-mistral

The standard paraview version on mistral expects either the lat/lon bounds to be present in the file you are opening, or a grid file matching the file you are currently opening with the name “grid.nc” in the directory of the data.
