v48 v49 53 53 PALM allows the output of instantaneous data as well as of temporally averaged data which is steered by the strings assigned to this parameter (see below).\\\\ 54 54 By default, cross section data are output (depending on the selected cross sections(s), see below) to local files [[../iofiles#DATA_2D_XY_NETCDF|DATA_2D_XY_NETCDF]], [[../iofiles#DATA_2D_XZ_NETCDF|DATA_2D_XZ_NETCDF]] and/or [[../iofiles#DATA_2D_YZ_NETCDF|DATA_2D_YZ_NETCDF]]. Volume data are output to file [[../iofiles#DATA_3D_NETCDF|DATA_2D_YZ_NETCDF]]. If the user has switched on the output of temporally averaged data, these are written seperately to local files [[../iofiles#DATA_2D_XY_AV_NETCDF|DATA_2D_XY_AV_NETCDF]], [[../iofiles#DATA_2D_XZ_AV_NETCDF|DATA_2D_XZ_AV_NETCDF]], [[../iofiles#DATA_2D_YZ_AV_NETCDF|DATA_2D_YZ_AV_NETCDF]], and [[../iofiles#DATA_3D_AV_NETCDF|DATA_2D_YZ_AV_NETCDF]], respectively.\\\\ 55 The filenames already suggest that all files have netCDF format. Informations about the file content (kind of quantities, array dimensions and grid coordinates) are part of the self describing netCDF format and can be extracted from the netCDF files using the command "ncdump -c <filename>". See [[../iofiles|netCDF data ]] about processing the PALM netCDF data.\\\\55 The filenames already suggest that all files have netCDF format.

See [[../iofiles|netCDF data 4.5.1]] about processing the PALM netCDF data.\\\\ 56 56 The following quantities are available for output by default (quantity names ending with '*' are only allowed for the output of horizontal cross sections):\\\\ 57 57 ||='''quantity name''' =||='''meaning''' =||='''unit''' =||='''remarks''' =|| … … 87 87 Example:\\\\ 88 88 '''data_output''' = '' 'u', 'pt_xz_av', 'w_xy', 'u_av' ''.\\\\ 89 This example will create the following output: instantaneous 3d volume data of u-velocity component (by default on file [[ DATA_3D_NETCDF]]), temporally averaged 3d volume data of u-velocity component (by default on file [[DATA_3D_AV_NETCDF]]), instantaneous horizontal cross section data of w-velocity component (by default on file [[DATA_2D_XY_NETCDF]]), and temporally averaged vertical cross section data of potential temperature (by default on file [[DATA_2D_XZ_AV_NETCDF]]).\\\\89 This example will create the following output: instantaneous 3d volume data of u-velocity component (by default on file [[../iofiles#DATA_3D_NETCDF|DATA_3D_NETCDF]]), temporally averaged 3d volume data of u-velocity component (by default on file [[../iofiles#DATA_3D_AV_NETCDF|DATA_3D_AV_NETCDF]]), instantaneous horizontal cross section data of w-velocity component (by default on file [[../iofiles#DATA_2D_XY_NETCDF|DATA_2D_XY_NETCDF]]), and temporally averaged vertical cross section data of potential temperature (by default on file [[../iofiles#DATA_2D_XZ_AV_NETCDF|DATA_2D_XZ_AV_NETCDF]]).\\\\ 90 90 The user is allowed to extend the above list of quantities by defining his own output quantities (see the user-parameter [[../userpar#data_output_user|data_output_user]]).\\\\ 91 91 The time interval of the output times is determined via [[dt_data_output]]. This is valid for all types of output quantities by default. Individual time intervals for instantaneous(!) 3d and section data can be declared using [[dt_do3d]], [[dt_do2d_xy]], [[dt_do2d_xz]], and [[dt_do2d_yz]].\\\\
