    14 Averaging interval for spectra output to local file [../?#DATA_1D_SP_NETCDF DATA_1D_SP_NETCDF] and/or  [../?#PLOTSP_X_DATA PLOTSP_X_DATA] / [../?#PLOTSP_Y_DATA PLOTSP_Y_DATA] (in s). \\\\
     14Averaging interval for spectra output to local file [../iofiles#DATA_1D_SP_NETCDF DATA_1D_SP_NETCDF] (in s). \\\\
    1515If this parameter is given a non-zero value, temporally averaged spectra data are output. By default, spectra data are not subject to temporal averaging. The interval length is limited by the parameter [#dt_dosp dt_dosp]. In any case '''averaging_interval_sp <= dt_dosp''' must hold. \\\\
    16 If an interval is defined, then by default the average is calculated from the data values of all timesteps lying within this interval. The number of time levels entering into the average can be reduced with the parameter [../?#dt_averaging_input_pr dt_averaging_input_pr]. \\\\
     16If an interval is defined, then by default the average is calculated from the data values of all timesteps lying within this interval. The number of time levels entering into the average can be reduced with the parameter [../d3par#dt_averaging_input_pr dt_averaging_input_pr]. \\\\
    1717If an averaging interval can not be completed at the end of a run, it will be finished at the beginning of the next restart run. Thus for restart runs, averaging intervals do not necessarily begin at the beginning of the run.

    4444Quantities for which horizontal spectra are to be calculated and output. \\\\
    4545Allowed standard values are: '''data_output_sp''' = '' 'u', 'v', 'w', 'pt', 'q' ''. The user may define further quantities ''' !!!(see chapter 3.5.4 part 5)!!! '''. \\\\
    46 Spectra are calculated using the FFT-method defined by [../?#fft_method fft_method]. \\\\
    47 By default spectra data are output to the local file [../?#DATA_1D_SP_NETCDF DATA_1D_SP_NETCDF]. The file's format is NetCDF. Further details about processing NetCDF data are given in ''' !!!chapter 4.5.1!!! '''. \\\\
     46Spectra are calculated using the FFT-method defined by [../inipar#fft_method fft_method]. \\\\
     47By default spectra data are output to the local file [../iofiles#DATA_1D_SP_NETCDF DATA_1D_SP_NETCDF]. The file's format is NetCDF. Further details about processing netCDF data are given in ''' !!!chapter 4.5.1!!! '''. \\\\
    4848The temporal interval of the output times of profiles is assigned via the parameter [#dt_dosp dt_dosp]. \\\\
    4949The vertical levels for which spectra are to be computed and output must be given by parameter [#comp_spectra_level comp_spectra_level]. \\\\
     
    5151Beside '''data_output_sp''', values '''must''' be given for each of the parameters,  [#comp_spectra_level comp_spectra_level], and [#spectra_direction spectra_direction], otherwise '''no''' output will be created! \\\\\\

    53 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 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 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.). \\
    54 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.
