 The general output format of PALM data is determined by the runtime-parameter [wiki:doc/app/d3par#data_output_format data_output_format] (data_output_format = 'netcdf', by default). For historical reasons, some alternative formats can be selected. The accuracy of the netCDF output data can be set with parameter [wiki:doc/app/d3par#netcdf_precision netcdf_precision]. By default, data have single (4 byte) precision. Runtime-parameter [wiki:doc/app/d3par#data_output_format data_output_format] can be used to choose between the different netCDF file formats (classic, 64-bit offset, netCDF4/HDF5). The 64-bit offset format allows creating large files (file size only limited by the underlying file system), but each output variable (array) is still limited to 2GB. In netCDF4 format, there is no limit for the size of variables, and it also allows parallel I/O into one output file. However, some (graphic) software still does not support netCDF4 format. 
 
-PALM allows the output of various data (e.g. cross sections, vertical profiles, timeseries, etc.) into different files. The following table gives an overview about the different kind of netCDF output data offered by PALM. Beside the local names of the files, the table also lists the minimum parameter settings which are necessary to switch on the output, as well as the parameters to be used to control the output.
