Re: error reading WRF grib2 files

Hi Fernando,
First of all, note these are just warnings. They do not impact the data, only the attributes describing it.

Our centers table is a bit out-of-date and entry 250 has not been added yet.
This entry should read "COnsortium for Small scale MOdelling (COSMO)".
You could fix this yourself if you have write access to /opt/ncl_ncarg/lib/ncarg/grib2_codetables/centers.table.
Just add the line
250:250:COnsortium for Small scale MOdelling (COSMO)
near the end of the file just before
254:254:EUMETSAT Operation Centre

If you don't have write access you can copy the whole /opt/ncl_ncarg/lib/ncarg/grib2_codetables/ directory tree to a location of your choosing and point to it using the environment variable NIO_GRIB2_CODETABLES.

As far as the other message is concerned, neither NCEP nor ECMWF currently defines a parameter 221 in 4.2.0.192.table (ECMWF does not even have this table yet). I can tell you that this table as a whole contains parameters that
belong to the discipline "Meteorological products" and the category "Covariance". Note, however, that parameters in the range 192-254 are, according to the GRIB2 documentation, "reserved for local use". That would mean someone at a COSMO site has a definition for this parameter. If this is documented anywhere, I don't know where that is. If you have any contact with the originator of your GRIB data, perhaps you can find out. If you do find a table listing their local parameters we could possibly see about incorporating it in our tables. By the way, this variable is in your file with the name: VAR_0_192_221_P0_L1_GME0.
