Decodes GRIB spectra stored as GRIB parameter 251. The results will be saved as a NetCDF file containing spectra in selected locations provided as input. The spectra are interpolated to these locations if possible.
gribspec2nc [-x] [-d timestep_hh][-i infile] [-l speclist.inp] [-o outfile] [-t itest] [-w weightfile]
-x: compute integrated parameters
-d timestep_hh: specify temporal resolution, default is 1 h
-i infile: GRIB input, default is input_spectra
-l speclist.inp: list of spectral locations to interpolate to,
default is speclist.inp
-o outfile: NetCDF output, default is output_spectra.nc
-w weightfile: Use precomputed interpolation weights, default is no
-s: issue a warning but generate NetCDF file even if there are missing GRIB fields (default is to issue error and abort)
-t: debug reporting:
itest: 0 (no diagnostics)
itest: 1 (some diagnostics)
itest: 2 (some more diagnostics)
itest: 3 (all diagnostics)
The input file can only contain one parameter (251) obtained for all directions and frequencies in the default order. Namely, the mars request should be done with DIRECTION=1/TO/nang, and FREQUENCY=1/TO/nfre. At this time nfre=30 and nang=24 for global model and for mediterranean data.
