Some parameters have no "shortName" defined in eccodes, or only as local extension. For instance, "ccc" (convective cloud cover) is OK in GRIB1 but not in GRIB2, unless the originating centre is ECMWF. "wt" for vertical velocity in m/s is only recognized for a few originating centres. For others, it is not recognized.
Currently, read_grib depends heavily on the shortName for finding parameters. Usually that is fine (and edition-independent), but it should be possible to allow for different keys. Of course, parameterNumber etc. are no longer independent of the grib edition number.
