NCEP Model Identifiers

The following CCCCs are non-site specific.  They are related
solely to centrally produced NCEP generated products.  Formerly,
all NCEP products were issued under the CCCC of KWBC; in order to
better differentiate the diverse suite of products produced by
NCEP, all centrally produced NCEP GRIB and BUFR products CCCC
headers will follow the convention of KWBx  KWDx where x
represents A-Z.

KWBC -- GLOBAL FORECAST SYSTEM 

KWBE -- North American Mesoscale (NAM) Model

KWBF -- NGM

KWBG -- RUC

KWBH -- MRF

KWBI -- SST/ SEA SURFACE TEMPERATURE

KWBJ -- WIND-WAVE FORECAST MODELS

KWBK -- GLOBAL ENSEMBLE FORECASTS

KWBL -- REGIONAL ENSEMBLE FORECASTS

KWBM -- Ocean Models/Extratropical Storm Surge Model

KWBN - ** NATIONAL DIGITAL FORECAST DATABASE (NDFD) PRODUCTS **

KWBO -- MERGE OF MODELS

KWBP -- AQM/AIR QUALITY MODEL 

KWBR -- Real Time Mesoscale Analysis/ Analysis of Error

KWBS -- Hires Window Model (ARW, NMM); Five Domains (West/East US, AK, HI, PR) 

KWBT -- GFS Downscale Guidance

KWBU -- Hurricane Wave Model

KWBV -- North American Ensemble Forecast System (NAEFS) - CMC

KWBW -- Real-Time Ocean Forecast System - RTOFS

KWBX -- ECMWF 

KWBZ -- REFER TO GRIB PDS

** The Identifier KWBN is part of the NDFD Program not NCEP. **
** The Identifier KWBQ is part of the MDL Program not NCEP. **
The identifiers KWBA-B, KWBY and KWDA-Z is reserved for future use.


MDL Model Identifiers

The following CCCCs are non-site specific.  They are related
solely to centrally produced MDL generated products.  All MDL
products are issued under the CCCC of KWBQ; in order to
better differentiate the diverse suite of products produced by
MDL, all centrally produced MDL products CCCC headers will 
follow the convention of KWEx where x represents A-Z.
The identifiers KWEW-Z is reserved for future use.

Future  use awaiting approval from FAA for KWFx (x=A-Z).
