MEMORANDUM FOR: Distribution E
FROM: Maxine M. Brown
Acting Deputy Director, NCEP Central Operations (NCO)
SUBJECT: Scheduled Operational Changes and Upgrades
<snip>
---- OPERATIONAL ANNOUNCEMENTS ----
1. The annual holiday moratorium on changes to the CCS Production Suite
will begin on Wednesday, 17 December 2008. With the transition to the
IBM Power6 system beginning in January 2009, the moratorium will
continue through approximately 1 April 2009.
The last date to submit Requests for Change (RFC) for minor implementations will be Monday, 20 November. For major changes, requiring extended parallel runs, the last day to submit RFCs will be Wednesday, 1 October.
As usual, changes to resolve operational problems will be accepted throughout the moratorium.
Our intention is to implement all CCS related RFCs by Tuesday, 16 December. Any outstanding CCS related RFCs remaining after that date will be returned to the users for testing and validation on the Power 6 system. Please let us know if you have any requests which must be implemented prior to the moratorium.
2. NCO is scheduling a 2-hour window twice a week for testing revisions to the RFC application software. Testing will be conducted on Tuesday and Wednesday from 0600L to 0800L beginning on Tuesday, 23 September 2008. All users should avoid using the Request for Change (RFC) application during this time or risk the possibility of losing or replicating data.
3. Upcoming major changes to NCEP's production suite and details on any product or timing changes associated with upcoming implementations can be viewed at the following website:
http://www.nco.ncep.noaa.gov/pmb/changes/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 feedback on the proposed changes can subscribe to the Model Evaluation mailing list via:
