ParaView

Paraview is an open-source software package for scientific visualization and data exploriation. It supports netcdf files and various other formats. The standard netCDF reader supports regular grids (e.g. ECHAM, MPI-OM). On mistral, we provide several versions with a special CDI-based reader, that supports irregular triangular meshes (e.g. ICON). We also have development versions, that support grib files, as well as grids with arbritrary numbers of vertices per cell (e.g. FESOM, IFS). Paraview comes with extensive documentation and a user forum. Below, we provide a couple examples and hints from our work with weather and climate data.

Figure 1: In-depth exploration of an ICON ocean data set in ParaView

The above example shows a complex visualization of an ICON ocean data set using ParaView. The viewport on the right displays the data, the selection made, as well as the Earth’s topography. The three viewports on the left hand side are used to specify the selection, based on a scatterplot matrix and parallel coordinates. These techniques are especially well-suited for an in-depth data analysis and exploration.

We regularly (well, COVID …) provide two-day courses on the use of paraview at DKRZ. If you are interested in such a course, please contact us via beratung@dkrz.de .
