Thanks this was very helpful indeed.

Review of what we discussed during our testing this afternoon:

ModelId   Label     Files
---------+---------+--------------------------------------------------------------
111       NMMB      
pgrb_biasc/sref_nmb.tCCz.pgrb212.(ctl|p1|n1|p2|n2|p3|n3).grib2
112       NMM       
pgrb_biasc/sref_nmm.tCCz.pgrb212.(ctl|p1|n1|p2|n2|p3|n3).grib2
113       SREF_113  
ensprod_biasc/sref.tCCz.pgrb212.(mean|prob|spread)_3hrly.grib2
116       WRF_EM    I don't have a URI for these

I downloaded all files for 20120724_0900 today from the FTP site you referenced
above.  Using 'wgrib2' I found that the ModelID ('wgrib2 -processid') in the 
various
types of output is, in fact:

ModelID   Label     Files
---------+---------+--------------------------------------------------------------
116       NMMB      
pgrb_biasc/sref_nmb.tCCz.pgrb212.(ctl|p1|n1|p2|n2|p3|n3).grib2
116       NMM       
pgrb_biasc/sref_nmm.tCCz.pgrb212.(ctl|p1|n1|p2|n2|p3|n3).grib2
113       SREF_113  
ensprod_biasc/sref.tCCz.pgrb212.(mean|prob|spread)_3hrly.grib2
116       WRF_EM    I don't have a URI for these

My point is that the ModelIDs for the NMMB and NMM grids are all 116 not 111 
and 112,
respectively.  So, the 'gribinsert' code was labeling the products appropriately
given its mapping of ModelID to name:

        [ModelID]

        case 111: return s_model_id("NAM",model);
        case 112: return "WRF_NMM";
        case 113: return s_model_id("SREF",model);
        case 114: return "NAEFS";
        case 115: return s_model_id("DGEX",model);
        case 116: return "WRF_EM";

(the routine s_model_id("SREF",model) returns SREF_113 for products with a 
ModelId
of 113, etc.)

Now the question is why the ModelIds for NMMB and NMM are 116 instead of
111 and 112, respectively?

Cheers,

Tom
