MEMORANDUM FOR:   Distribution E

FROM:             John H. Ward
                 Chief, Production Management Branch

SUBJECT:          Changes to the NWS Production Suite

    On 15 July 2003 all FAX charts based on output from the Nested Grid Model 
(NGM) will be removed from the NWS FTP server.  A list of products to be 
eliminated is contained at the end of this memo.  Alternate products can be 
found at:


    NGM MOS FAX products can be found at:


    On or about 1 July 2003 NCEP will be instituting a policy to limit access 
to restricted data to authorized users of the NCEP Central Computer System.  
All ftp and WEB access to these restricted data types will be terminated on 
that date.  Further details on restricted data can be found at:


    The 30-day operational readiness test for the new Central Computer System 
(CCS) is continuing.  It is anticipated that the CCS will not become 
operational prior to 8 May 2003.  An exact date will be determined as soon as 

    In order to reduce the impact of this delay on planned implementations, the 
moratorium on changes to the Production Suite is being lifted and Production 
Management Branch will now accept requests for changes.  Routine 
implementations will commence by late April.  For changes that do not require 
additional system resource, implementations will be performed on both the IBM 
SP and the CCS.  Changes that require additional system resources, such as the 
GFDL upgrade and the initiation of a Fire Weather run, will be implemented on 
the CCS only.  Products related to the CCS implementations will not be 
available until the CCS becomes operational.

    By implementing changes on the CCS that are not on the IBM SP, the switch 
over to the CCS will not be as transparent as previously advertised.  The NCO 
WEB page which lists upcoming changes to the Production Suite


will indicate whether upcoming changes will be made on the CCS only or on both 
systems.  Once the operational date is established, this WEB site can be used 
to determine what changes in product volume, content, or format that will occur 
when the CCS becomes operational.

    The Production Status WEB page for the parallel runs on the
CCS is available at:


    The 30-day average times contained on this WEB page should closely mirror 
the schedule on the IBM SP prior to the T254 Global Forecast System (GFS) 
implementation.  The parallel status page now contains the target completion 
times for specific forecast products from each model run.  As model upgrades 
are implemented, every effort will be made to deliver products no later than 
the target times indicated.  No changes will be made to these target times 
without discussions with the customers of NCEP products.  In a number of cases 
the target times do not currently match the 30-day average completion time.  
The target times are based on plans to adjust the production suite to conform 
to a completely symmetric six hour forecast cycle, after the transition to the 
CCS is completed.

    An on-line user guide for code conversion to the CCS is available on the 
NCEP internal WEB server at:


    The guide will be continually updated as new features or problems with the 
code conversion are uncovered.
