[ncl-talk] Getting error while converting .grib file to netcdf format.

[Guido Cioni]

The error is exactly telling what the problem is :) In order to work with grib2 files you have to configure and compile CDO (and any other command line tool) with grib2 libraries (--with-grib-api). However, I don't understand what the problem is: Dennis already provided you with a converted NETCDF file...
