If you use ncl_filedump on your GRIB2 file you will see that it has no time dimension. There is only a lat and a lon dimension. The script you are using is trying to read a time dimension that does not exist -- therefore the error. The simplest and most general way to convert any GRIB file to NetCDF is to use the script ncl_convert2nc, which is supplied with every NCL installation. If the 'ncl' binary is in your PATH then ncl_convert2nc will be as well, assuming you have a standard installation.

I was using slightly modified form of an example in NCL page https://www.ncl.ucar.edu/Applications/gribeff.shtml to convert grib2 file to netcdf. However, ncl cannot read the time information from input grib2 file and stops where "initial_time?" is mentioned. Grib2 file and ncl code are attached. Any help is appreciated.


 Thanks.
