Dataset
Summary
The data used in this contest is part of a larger simulation ans shows the weather over central Europe for April 26, 2013. The simulation uses COSMO reanalysis forcing data from exactly this day. Internally, the simulation was computed on the original ICON grid, but was additionally resampled to a rectilinear lat/lon grid for easier data access. The visualization tasks, however, also include visualizations of the data on the original ICON grid.
The data is organized as netCDF data files. Almost all visualization applications can read and visualize regular lon/lat netCDF data, while some are also able to read and render ICON data on it original unstructured grid. One of which is ParaView, which is also part of our regular workflow.

Variables
The data files include the labeled 2D or 3D variables, as well as the lon/lat grid description, or the ICON grid description. The temporal resolution for 3D variables is 1 minute, for the 2D variables 10 seconds. The variable Z_IFC is only available for the lon/lat grid, but as all data is georeferenced, it can also easily be combined and used with the ICON data too. You can check the variables and the dimensions of a netCDF file using the command 'ncdump -h dataset.nc". Some of the variables also feature missing values, which means that at those positions a data value is not defined. Within a netCDF data file, this is shown using a missing_values or a _FillValues attribute. The following variables are available in the netCDF files:

3D Grid:
HUS - specific humidity (measured in kg/kg)
CLW - specific cloud water content (measured in kg/kg)
CLI - specific cloud ice content (measured in kg/kg)
QR - rain mixing ratio (measured in kg/kg)
UA - zonal wind (measured in m/s)
VA - meridional wind (measured in m/s)
WA - vertical wind (measured in m/s)
TA - air temperature (measured in K)
PRES - air pressure (measured in Pa)

2D Grid:
Z_IFC - half grid levels i.e. height above sea level (measured in m)
CLT - total cloud cover (measured in %)
CCT - cloud top pressure (measured in Pa)
CCB - cloud base pressure (measured in Pa)
T_CTOP - cloud top temperature (measured in K)
T_CBASE - cloud base temperature (measured in K)
U_10 - zonal wind at 10m height (measured in m/s)
V_10 - meridional wind at 10m height (measured in m/s)
RUNOFF_S - weighted surface water runoff (measured in kg/m²)

Files
The full size data is available for 240 minutes, while the two smaller data sets have 20 minutes or 1 minute respectively. The flight trajectories are provided as MATLAB table with a description of the table layout. The 2D/3D data showing the three different domains is only available as ICON data with 2D data only containing the cloud but not the surface variables.
