  NAME

gpv2nc - Converts GPV files into a NetCDF file

The Converter of Grid Point Value date file made by Japan Meteorological Agency(JMA) to NetCDF file.

  SYNTAX
    % gpv2nc [-ihd] [-r arg_ranges] [-o output_file] [-s stime] [-e etime] gpv_files..

  DESCRIPTION

gpv2nc convert Grid Point Value (GPV) data made by Japan Meteorological Agency (JMA, or Kishou-cho) to NetCDF. Currently supports only the Domestic Binary format.

  OPTIONS

-o output_file:
    output file name (if omitted, determined internally)

-h: help (to show this message)

-d :
    debug mode (does extra printing)

-r :

    • to specify packing (compression) using the add_offset and
        scale_factor attributes.

    • SYNTAX (EXAMPLE): -r u,v,-200..200;temp,-150..100

    • This means that variables named u, v, and temp are packed
        into short integer to cover the ranges -200 to 200 (for u
        and v) and -150 to 100 (for temp). Other variables, if any,
        will not be packed, so they will be stored as single-precision
        float.

-s :
    start time relative to the beginning of the forecast [hours] (data before this time in each input file are excluded from the output file)

-e :
    end time relative to the beginning of the forecast [hours] (data after this time in each input file are excluded from the output file)

-i :
    shows info on the input file (does not dump a file, but creates a temporarlly file -- if you do not have a write permission of the current directory, specify one you have it by the envronmental variable TMPDIR. Example: % export TMPDIR=/tmp).
