The user may define [../userint/output further quantities]. \\\\ 53 Spectra are calculated using the FFT-method defined by [../ini par#fft_method fft_method]. \\\\54 '''Attention: Computation of spectra is currently not possible with [../ini par#fft_method fft_method]''' = 'fftw'. \\\\53 Spectra are calculated using the FFT-method defined by [../initialization_parameters#fft_method fft_method]. \\\\ 54 '''Attention: Computation of spectra is currently not possible with [../initialization_parameters#fft_method fft_method]''' = 'fftw'. \\\\ 55 55 By default, spectra data are output to the local file [../iofiles#DATA_1D_SP_NETCDF DATA_1D_SP_NETCDF]. The file's format is netCDF and can be visualized by any graphic software which provides a netCDF interface (e.g. [../ncl NCL], [http://www.ferret.noaa.gov/Ferret/ ferret] or [http://meteora.ucsd.edu/~pierce/ncview_home_page.html ncview]). \\\\ 56 56 The temporal interval of the output times of profiles is assigned via the parameter [#dt_dosp dt_dosp]. \\\\ … … 59 59 Beside, '''data_output_sp''', values '''must''' be given for [#comp_spectra_level comp_spectra_level] and [#spectra_direction spectra_direction], otherwise, '''no''' output will be created! \\\\ 60 60 61 Calculation of spectra requires cyclic boundary conditions along the respective directions (see [../ini par#bc_lr bc_lr] and [../inipar#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 heights 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.).61 Calculation of spectra requires cyclic boundary conditions along the respective directions (see [../initialization_parameters#bc_lr bc_lr] and [../initialization_parameters#bc_ns bc_ns]).
