+Calculation of spectra requires cyclic boundary conditions along the respective directions (see [../?#bc_lr bc_lr] and [../?#bc_ns bc_ns]). The spectra are ordered with respect to their output times. Spectra can also be temporally averaged (see averaging_interval_sp ). Each data point of a spectrum is output in a single line (1st column: wavenumber, 2nd column: spectral coefficient). If spectra are to be calculated and output for more than one height (see comp_spectra_level), the spectral coefficients for the further heighs can be found in the subsequent columns. The order of the data in the file follows the order used in the assignment for data_output_sp (data_output_sp = 'u', 'v',… means that the file starts with the spectra of the u-component, followed by the v-component spectra, etc.). Additional to the files PLOTSP_X_DATA and PLOTSP_Y_DATA which contain the data, PALM creates NAMELIST parameter files (local name PLOTSP_X_PAR and PLOTSP_Y_PAR) which can be used as parameter input file for the plot software profil. Spectra can be directly plotted with profil using the data and the corresponding parameter file. The plot layout is steered via the parameter input file. The vertical levels for which spectra are to be plotted must be given by plot_spectra_level. Otherwise, no spectra will appear on the plot, although data are available on file. All parameter values can be changed by editing the parameter input file.
