1. Grib1 To Grib2 Converter Youtube Full

Hi, is there an option that I can use XyGrib to convert a grib2 file into a grib 1 file? Or does anyone know a tool for this?

1. It is described in the WMO GRIB2 Document FM92-X11 GRIB. (see: NCEP WMO GRIB2 Documentation, provided by the National Centers for Environmental Prediction (NCEP), it has complete tables, but is missing the notes and regulations.) The problem, when the NDFD first came out, was that the only way to decode a GRIB2 message was to use the GRIB2 library.
2. Some reanalysis data comes in grib format but I have a personal preference for NetCdf data because it is usually easier to load into your favourite programming or scripting language. An easy solution is to convert grib to netcdf. The following bash script uses NCL in a loop to convert every grib files in a given folder into netcdf files.

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.

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:

One 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

ECMWF has a command line based tool to do just this: https://software.ecmwf.int/wiki/display/GRIB/grib_to_netcdf
