| 141 | PALM allows the output of instantaneous data as well as of temporally averaged masked data which is steered by the strings assigned to this parameter (see below). Up to 20 different locations for masked data can be defined. Each location can output different quantities. The locations are steered with the parameters [#mask_x mask_x], [#mask_y mask_y], [#mask_z mask_z], [#mask_x_loop mask_x_loop], [#mask_y_loop mask_y_loop] and [#mask_z_loop mask_z_loop].\\\\ |
| 142 | By default, masked data are output to local files [[../iofiles#DATA_MASK_01_NETCDF|DATA_MASK_01_NETCDF]], [[../iofiles#DATA_MASK_02_NETCDF|DATA_MASK_02_NETCDF]], [[../iofiles#DATA_MASK_20_NETCDF|DATA_MASK_20_NETCDF]]. The file's format is netCDF. Further details about processing netCDF data are given in chapter [[4.5.1]].\\\\ |
