The grib2 files have the following details

center=7 (NCEP)  subcenter=7 (CPC)     for files created on Gaea
center=7 (NCEP)  subcenter=3 (NCO)     for files created on wcoss2 with NCO testing codes
center=7 (NCEP)  subcenter=3 (NCO)     for files created by NCEP Central Operations

processid = 101 (CORe)


wgrib2lib problem:
  wgrib2lib was creating legal grib files but unused level information was 
not consistent.  The newer versions set the "scale factor of the first fixed surface" 
and "scaled value of the first fixed surface" to 0xFF and 0xFFFFFF.  Older versions
set the values to 0x81 and 0x810000.  Any value is correct.  However, some programs
demand consistency.  For example, in the transition between the Gaea dn wcoss2
produced files, wgrib2lib was updated.  The wgrib2 averaging option wasn't able to
handle averaging over the transistion.

The historical grib2 files are legal grib2.  However they differ in the subcenter
and unused table entries from the operational grib2 files.  Some programs demand
constancy.  

Convert Gaea grib2 to wcoss2 grib2,  Must use wgrib2 v3.1.1+.
