v361 v362 263 263 '''data_output''' = '' 'u', 'theta_xz_av', 'w_xy', 'u_av' ''. 264 264 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]]).\\\\ 265 The user is allowed to extend the above list of quantities by defining his own output quantities (see the user-parameter [[../user par#data_output_user|data_output_user]]).\\\\265 The user is allowed to extend the above list of quantities by defining his own output quantities (see the user-parameter [[../user_parameters#data_output_user|data_output_user]]).\\\\ 266 266 The time interval of the output times is determined via [#dt_data_output 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_do3d], [#dt_do2d_xy dt_do2d_xy], [#dt_do2d_xz dt_do2d_xz], and [#dt_do2d_yz dt_do2d_yz].\\\\ 267 267 Also, an individual time interval for output of temporally averaged data can be assigned using parameter [#dt_data_output_av dt_data_output_av]. This applies to both 3d volume and cross section data. The length of the averaging interval is controlled via parameter [#averaging_interval averaging_interval].\\\\ … … 270 270 Cross sections extend through the total model domain. In the two horizontal directions all grid points with 0 <= i <= [[../initialization_parameters#nx|nx]]+1 and 0 <= j <= [[../initialization_parameters#ny|ny]]+1 are output so that in case of cyclic boundary conditions the complete total domain is represented. The location(s) of the cross sections can be defined with parameters [#section_xy section_xy], [#section_xz section_xz], and [#section_yz section_yz]. Assigning '''section_...''' = ''-1'' causes the output data to be averaged along the direction normal to the respective section.\\\\ 271 271 '''Output of user-defined quantities:'''\\\\ 272 Besides the standard quantities from the above list, the user can output any other quantities. These have to be defined and calculated within the user-defined code (see [[../userint/output|User-defined output quantities]]). They can be selected for output with the user-parameter [[../user par#data_output_user|data_output_user]] for which the same rules apply as for '''data_output'''. Output of the user-defined quantities (time interval, averaging, selection of cross sections, etc.) is controlled by the parameters listed above and data are written to the same file(s) as the standard quantities.\\\\272 Besides the standard quantities from the above list, the user can output any other quantities.

After PALM has finished, the contents of these individual files are sampled into one final file using the program {{{combine_plot_fields.x}}} (automatically called by '''palmrun''').\\\\ … … 335 335 '''Mask 3''': Instantaneous data of potential temperature, u-, v- and w-velocity component (by default on file 336 336 [[../iofiles#DATA_MASK_02_NETCDF|DATA_MASK_03_NETCDF]])\\\\ 337 The user is allowed to extend the above list of quantities by defining his own output quantities (see the user-parameter [[../user par#data_output_masks_user|data_output_masks_user]]).\\\\337 The user is allowed to extend the above list of quantities by defining his own output quantities (see the user-parameter [[../user_parameters#data_output_masks_user|data_output_masks_user]]).\\\\ 338 338 The time intervals of the output times for each mask are determined via [#dt_domask dt_domask].\\ 339 339 Individual time interval for output of temporally averaged data can be assigned using the parameter [#dt_data_output_av dt_data_output_av]. The length of the averaging interval is controlled via parameter [#averaging_interval averaging_interval]. No particular parameters are existent for steering the time-averaged output of each separate mask.\\\\ … … 465 465 Profile names preceded by a hash automatically imply that profiles for these variables are also output at later times. It is not necessary and not allowed to specify the same profile name with and without hash simultaneously(this would lead to a netCDF error).\\\\ 466 466 These initial profiles have been either set by the user or have been calculated by a 1d-model prerun.\\\\ 467 The user is allowed to extend the above list of quantities by defining his own output quantities (see the user-parameter [[../user par#data_output_pr_user|data_output_pr_user]]).467 The user is allowed to extend the above list of quantities by defining his own output quantities (see the user-parameter [[../user_parameters#data_output_pr_user|data_output_pr_user]]). 468 468 }}} 469 469 |----------------
