MATLAB-CDI is a collection of MATLAB functions that import/read GRIB and netCDF files through high-level function calls that follows an unified syntax. The package supports a subset of the full GRIB and netCDF format specification typically produced by climate models.
Wgrib2: changes since 5/2012. Operational wgrib2 on NCEP’s WCOSS is 5/2012 version. Grb1to2.pl grib1 to grib2 converter, perl script that. Calls wgrib and wgrib2. Easy to build? Grib2 using these routines. Modifications were painless. Grb1to2.pl - grib1 to grib2 converter Grb1to2.pl converts grib1 files to grib2. This perl script uses wgrib, wgrib2 and a few minor programs that are included with the wgrib2 package (gmerge, smallest_grib2).
Technically speaking, MATLAB-CDI consists of mex-interfaces to the CDI library that read GRIB/netCDF. CDI is the basic library underlying the famous CDO (Climate Data Operators) developed by Max-Planck Institut für Meteorologie in Hamburg. The MATLAB-CDI interface package has been developed by The MathWorks Consulting on behalf of the Rossby Centre, SMHI.

MATLAB-CDI has been compiled and tested under Linux and Windows. The Linux installation is straightforward, while the Windows installation in the worst case requires experience of how to compile and install programs in a Linux-like environment such as cygwin or MinGW. (Actually, it's not the MATLAB-CDI package that causes the problems, it's the netCDF and CDI libraries that need to be compiled under Windows, nothing for the faint-of-heart.)

I know there is software like wgrib2 that will convert files in grib and grib2 format to NetCDF files, but I need to go the other way: from NetCDF to grib2, because the local weather offices here can only consume gridded data in grib2 format.
It appears that one solution could be in Python, using the NetCDF4-Python library (or other) to read the NetCDF files and using pygrib to write grib2.

Is there a better way?

After some more research, I ended up using the British Met Office 'Iris' package (http://scitools.org.uk/iris/docs/latest/index.html) which can read NetCDF as well as OPeNDAP, GRIB and several other formats, and allows to save as NetCDF or GRIB.
Liquid xml studio community edition 2009 gmc. Yes, Liquid XML Studio 2009 Community Edition is still 100% FREE for commercial and non-commercial use!! We obviously believe Liquid XML Studio 2009 is the best graphical XML schema editor available, but amazingly you can still use it under the community edition license for FREE.

Basically the code looks like:
But if your netcdf file doesn't contain sufficient metadata, you may need to add it, which you can also do with Iris. Here's a full working example:
Rich SignellRich SignellOne can also use climate data operators (cdo's) for the task -https://code.zmaw.de/projects/cdo/wiki
but need to install the software with all additional libraries.

I know CDO is mentioned above, but I thought it would be useful to give the full command
