[Linda Miller]

FROM:              John H. Ward
              Chief, Production Management Branch

SUBJECT:          Changes to the NWS Production Suite

1.  The annual December moratorium on changes to the Production Suite 
will begin at close of business on Tuesday, 18 December and will end on 
Tuesday, 8 January.  Any request for changes to the Production Suite 
must be received by Wednesday, 28 November in order to be considered for 
implementation prior to the moratorium.

2.  All NCEP model derived GRIB1 data currently residing on the NCEP and 
TOC FTP servers will be removed on 28 January 2008.  Equivalent GRIB2 
data sets are available on both servers.  NOAAPORT data will not be 
impacted by this change.

NCEP provides software to convert GRIB2 formatted data back into GRIB1. 
Please use the link below to obtain the software utility to convert 
formats:

http://www.nco.ncep.noaa.gov/pmb/codes/GRIB2/

Information regarding product equivalents for GRIB1 and GRIB2 on the NWS 
FTP TOC servers (tgdata.nws.noaa.gov and tgftp.nws.noaa.gov) and NCEP 
ftp server (ftp.ncep.noaa.gov) can be found via the link below:

http://www.nco.ncep.noaa.gov/pmb/docs/GRIB1_to_GRIB2.shtml

Please direct all questions concerning the software codes to the
following NCO PMB Dataflow Helpdesk: NCEP.PMB.Dataflow at noaa.gov

product or timing changes associated with upcoming implementations can

Test data for each of these proposed changes should be available six 
weeks prior to implementation.  Anyone wishing to receive formal notice 
of the final pre-implementation testing and the opportunity to provide
