Re: suppress print out from grib to netCDF scripts

Hi Naoki,

Are you aware of "ncl_convert2nc" which allows you to convert GRIB and other supported file formats (HDFEOS, HDF4, etc) to NetCDF on the UNIX command line?

   ncl_convert2nc /file/location/data.grb

For more information see:

http://www.ncl.ucar.edu/Document/Tools/ncl_convert2nc.shtml

I don't know why your script below is printing the variables, since you don't have any obvious "print" statements.

What does the output look like?
