Dear Robb,
If you are working with raw GRIB data then as defined by WMO,
in GRIB section 1
Byte 4 is the code table number
Byte 5 is the centre identifier and 98 is used for ECMWF data.
Most ECMWF atmospheric data uses ECMWF local GRIB table 128 and
wave data uses ECMWF local GRIB table 140. A few ERA-40 fields
use other table as do some EPS, seasonal and monthly forecasts
fields, but the table is always in section 1.
I hope this helps.

Keith
