-Information about surface properties as well as the actual physical conditions at horizontal and vertical surfaces can be visualized with Paraview via VTK-files which allows the input of unstructured data. 
-With revision -r 3421 PALM allows the output of instantaneous and time-averaged unstructured surface data, i.e. from horizontally and vertically orientated surfaces (building walls and roofs, Earth surface). These data can be further processed into Paraview readable VTK files, in order to visualize surface properties such as surface temperature or radiation balance, etc..
-Output is written into binary files [[../iofiles#SURFACE_DATA_BIN|SURFACE_DATA_BIN]] and  [[../iofiles#SURFACE_DATA_AV_BIN|SURFACE_DATA_AV_BIN]], respectively. Please note, for the moment, each MPI-process writes into a single file. This may be revised later. 
+Information about surface properties as well as the actual physical conditions at horizontal and vertical surfaces can be output in NetCDF format (parallel NetCDF4 installation required) or in binary format. The binary output can be further processed and visualized with Paraview via VTK-files which allows the input of unstructured data. 
+The binary data can be further processed into Paraview readable VTK files using the script [[../../../../browser/palm/trunk/UTIL/surface_output_processing|surface_data_to_vtk]], in order to visualize surface properties such as surface temperature or radiation balance, etc..

 Please note, in order to visualize surface data with Paraview, the PALM output data needs to be further converted into the VTK file format in the post-processing. A suitable post-processing tool is provided under {{{/trunk/UTIL/surface_output_processing/surface_output_to_vtk.f90}}}. This tool comes with an additional namelist file {{{surface_output_parin}}}, where output specific information such as cycle number, path to the output data, etc. needs to be defined.
