MEMORANDUM FOR:Distribution E
FROM:Allan Darling
Deputy Director, NCEP Central Operations (NCO)
SUBJECT:Scheduled Operational Changes and Upgrades
<snip>
----OPERATIONAL ANNOUNCEMENTS----
1.The CCS Implementation Standards have been updated and are available at
http://www.nco.ncep.noaa.gov/pmb/docs/.Please adhere to these standards
when submitting changes for the CCS.
2.The following information is being shared to clarify questions
regarding the NOMADS systems.NOAA operates four types of NOMADS Servers
that host NCEP Model Products:
* A near-real-time server supported by NCDC is available at
http://nomads.ncdc.noaa.gov/.This server provides:
o access to a subset of NCEP's operational data set (as distributed on
NOAAPort) shortly after distribution
o a long-term archive for all data sets
o many other data sets (see
http://nomads.ncdc.noaa.gov/data.php?name=inventory)
* A real-time server supported 24x7 by NCEP is available at
http://nomads.ncep.noaa.gov/.This server provides:
o access to NCEP's operational data sets as they are being generated
o a short-term archive of up to a month for most data sets
o 24x7 operational monitoring by NCEP staff
o A geographically-diverse backup server to insure operational availability
* Four non-operational research and development servers used for
customer testing of new products and services prior to operational
implementation
o These servers are not guaranteed to have current data
o These servers are not guaranteed to be available at all times
o These servers and their content are supported only during business
hours and on the basis of staff availability
o Three non-operational research and development servers managed by NCEP
are available at:
* http://nomad1.ncep.noaa.gov/ncep_data/index.html
* http://nomad3.ncep.noaa.gov/ncep_data/index.html
* http://nomad5.ncep.noaa.gov/ncep_data/index.html
o A non-operational research and development server managed by NCDC is
available at http://nomads6.ncdc.noaa.gov/ncep_data/index.html
* NOAA's Geophysical Fluid Dynamics Laboratory has select Climate Model
(CM.x) output for access at:
o http://nomads.gfdl.noaa.gov/CM2.X/
o http://nomads.gfdl.noaa.gov
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:
