Example of a PALM netCDF data set

The netCDF dataset described here contains data of instantaneous horizontal cross sections and has been created using the settings of the example parameter file (see the explanation), i.e. it contains section data of the w-velocity-component and of the potential temperature for vertical grid levels with index k = 2 and k = 10, selected by the respective parameter settings data_output = 'w_xy', 'pt_xy', and section_xy = 2, 10. Output has been created after every 900 s (dt_data_output = 900.0). Because of end_time = 3600.0, the file contains data of 4 time levels (t = 900, 1800, 2700, 3600 s). Supposed that the name of the netCDF dataset is example_cbl_xy.nc, an analysis of the file contents using the command

ncdump -c example_cbl_xy.nc

will create the following output. The original ncdump output is displayed using monospace, additional explanations are given in italian.
