Rodrigo,


Your assumptions are correct, the details are in
README.perldecoders file that contains instructions included with
the release.  If you use the -v flag then the log file will contain ascii
description of the decoder variables.

Robb...


3) General operations notes:

  i) metar2nc [-v] metar.cdl [dataDir] [yymm] 
        uses station file: sfmetar_sa.tbl

 ii) buoy2nc [-v] buoy.cdl [dataDir] 

iii) ua2nc [-v] ua.cdl [dataDir] [yymm]
        uses station file: snworld.tbl

 iv) syn2nc [-v] syn.cdl [dataDir] [yymm] 
        uses station file: systns_upc.tbl


where
 
   -v        Verbose flag; logs each expanded report in log file. 
             Use for testing only; creates large log files.  

   cdl file  Required, contains all the meteorological variables; self 
             documenting.

   dataDir   Data directory; default is current directory. 
             For netCDF output files.  

   yymm      The year and month; default is current year and month.

   Decoders expect input on stdin, exit in 20 minutes if no activity.

   Decoders create files ending with 'lst' that designate the list of
   currently processed reports and the record number in the file. Each 
   decoder also creates files ending with 'Log.nc' that show the status 
   of the decoder. The data files have the following format:

             yymmddhh_{decoder name}.nc
