Subject: Addition of WMO Headers to 2.5-km GFS-based Gridded
MOS GRIB2 Products on NWS FTP Server Effective on
or about December 13, 2012
On or about Thursday December 13, 2012, beginning with the 1200
Universal Coordinated Time (UTC) model run, WMO headers will be
added to the experimental 2.5-km GFS-based gridded MOS GRIB2
products on the NWS FTP server. At the present time these
products do not contain WMO headers. On the change date, each
element-specific GRIB2 file will contain a super header and
individual headers for each forecast projection. GRIB2 file
names for each gridded MOS element are listed in Table 1
below. Representations of the WMO super headers are listed in
Table 2 below.
These GRIB2 products are available in the experimental area of
the National Digital Guidance Database (NDGD) on the NWS ftp
server. Forecast guidance for Days 1 through 3 is available at:
ftp://tgftp.nws.noaa.gov/SL.us008001/ST.expr/DF.gr2/DC.ndgd/GT.mo
sgfs/AR.conus/VP.001-003/
Forecast guidance for days 4 through 7 is available at:
ftp://tgftp.nws.noaa.gov/SL.us008001/ST.expr/DF.gr2/DC.ndgd/GT.mo
sgfs/AR.conus/VP.004-007/
