MEMORANDUM FOR: Distribution E
FROM: Allan Darling
Deputy Director, NCEP Central Operations (NCO)
SUBJECT: Scheduled Operational Changes and Upgrades
<snip>
____________________________________________
---- SOFTWARE IMPLEMENTATIONS ----
The following item will be implemented at 12Z on Monday, 23 March:
148. NAWIPS - Systems NCOSRV, COMPUTEFARM. (Plummer, NCO). This change
adds information to the GEMPAK / NAWIPS image identification table,
imgtyp.tbl, to allow proper display and navigation of the new blended
images.
______________________________________________
The following item will be implemented at 09Z on Tuesday, 24 March:
149. SCRIPT - IBM Job CFS_POST. (Zhu, EMC). Scripts cfs_time.sh and
cfs_post.sh are being modified to correct an error which has caused
incomplete ocean GRIB and pressure GRIB files in the CFS model. The
files were being alerted for dissemination in the cfs_post.sh script,
but additional fields were being added to these files in the cfs_time.sh
script. The alert has been moved to the "cfs_time.sh" step.
______________________________________________
The following items will be implemented at 12Z on Tuesday, 24 March:
150. DBNET - System NOMADS. (Freeman, NCO). The gens1x1.ctl template
file on the NOMADS hosts will be modified to define only one member.
This change will reduce the size of the GrADS index file to reflect only
the single member that is actually mapped, instead of containing
undefined values for the other 19 members.
151. DBNET - System NOMADS. (Freeman, NCO). DBNet changes are being made
to begin creating daily RTOFS control files on NOMADS. The hourly and
daily files are also being placed in separate directories.
152. SCRIPT - IBM Job JPROD_CLEANUP.XX, where XX=00,12. (Mabe, NCO). The
cleanup scripts are being modified to keep more NAWIPS gridded data in
/com/nawips/prod on the CCS for the GFS, UKMET, ECMWF and GDAS models.

---- HARDWARE IMPLEMENTATIONS ----
There are no hardware changes scheduled for next week.

---- OPERATIONAL ANNOUNCEMENTS ----
1. The transition to the IBM Power6 system has begun. We are currently
in a moratorium for CCS changes through approximately 1 July 2009.
As usual, changes to resolve operational problems will be accepted
throughout the moratorium.
2. NCEP Central Operations (NCO) is preparing the WWB 5th floor
swing-space for NCWCP testing. The WWB swing-space will be provisioned
with a scaled-down version of the NCWCP data center. NCWCP future
tenants will use the swing-space to test operational applications and
processes in preparation for the WWB-NCWCP transition.
The overview of the schedule is:
* Nov – Dec 2008: NCO provisions WWB 5th floor swing-space with a
scaled-down version of the NCWCP data center and NCWCP LAN
* Jan – Apr 2009: NCWCP future tenants test operational applications and
processes using the WWB swing-space
* May – Sep 2009: NCO leads the IT provisioning for the NCWCP IT
infrastructure
* Sep - Dec 2009: Tenants move to NCWCP, vacate WWB
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:

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:
