Re: Reading ECHAM grib files

These are warning messages.

NCL has multiple GRIB tables built into it. This allows
NCL to assign the appropriate meta data (long_name, units, etc).

NCL unpacks these variables correctly. It just does not
have the meta data available. You must access
the appropriate GRIB table.

If you have a sample file and the appropriate GRIB table (or
point us toward the table), it will be added to the next release
of NCL.
