[ldm-users] cnvgrib Utility Help

Hi all,

I am using NCAR's cnvgrib utility to convert grib2 RUC-Analysis data to
grib1.  An example of one of these data files is below:


When I run the command,

-g21 ruc2anl_130_20090605_2200_000.grb2 ruc2anl_130_20090605_2200_000.grb

the converting process seems to work.  I get a file with an extension of
"grb."  However, while the file type is listed as a data file, it appears
green, as an executable file.  In addition, the code I am using does not
recognize the file as a grb1 file.  (The code only recognizes grb1 files.)
 The website to which I referred to use this utility (
http://blog.nssl.noaa.gov/wdssii/) did not list any additional options to
use besides the required '-g21.'  Am I missing something?  This is my first
implementation of the cnvgrib utility, so I apologize if I have made a
naive mistake.  I appreciate any help.

Best regards,

Michelle Serino
