SUBJECT: Changes to the NWS Production Suite
1. Installation of the CCS Phase II system has begun. The transition of NCEP
operations to the Phase II system is expected to begin in mid September 2004, with
the system expected to become operational on or about 18 January 2005. A moratorium
on changes to the Production Suite is expected to begin on or about 21 September and
end in January 2005. Changes required to correct operational failures will continue
to be made during the moratorium.
Major implementations scheduled prior to the moratorium are: Aug 17 - SREF diversity upgrade Aug 24 - Coupled-Climate Forecast System (CFS) Sept 21 - Hi Res Window WRF ensemble 2. The transition in the file naming convention for the GlobalForecast System (GFS) has begun. On 14 June 2004, a duplicate file structure was established on both the TOC and NCEP FTP servers. All file structures containing AVN now have a duplicate link containing GFS. These duplicate file structures will remain in place for six months. On approximately 18 January 2005, all file structures containing AVN will be eliminated. Additional details about this transition can be found at the following web site:

3. NCEP Central Operations is implementing a new DNS solution for World Weather
Building (WWB), Camp Springs, MD. The deployment of the new DNS solution is
scheduled to commence 23 August 2004. A component of the DNS solution is the
retirement of the "wwb.noaa.gov" and "fb4.noaa.gov" DNS domains. The domain
"ncep.noaa.gov" is and will be supported in lieu of the "fb4" and "wwb" domains.
Scripts that access NCEP hostnames using the "wwb.noaa.gov" should be changed to "ncep.noaa.gov" by 1 August 2004. For example, if accessing "ftpprd.wwb.noaa.gov", change to "ftpprd.ncep.noaa.gov". Changes to scripts should be made by 1 August 2004. This will allow time to address problems before the deployment of the new DNS system. For internal NCEP users, a separate communications will provide further instructions. If there are any questions or concerns, please email ncep.helpdesk@xxxxxxxx and copy Luis.Cano@xxxxxxxx.
