MEMORANDUM FOR: Distribution E
FROM: Allan Darling
Deputy Director, NCEP Central Operations (NCO)
SUBJECT: Scheduled Operational Changes and UpgradesThe following information is being shared to clarify questions regarding the NOMADS systems. NOAA operates three types of NOMADS Servers that host NCEP Model Products: A real-time server supported 24x7 by NCEP is available at http://nomads.ncep.noaa.gov/. This server provides:
- access to NCEP's operational data sets as they are being generated
- a short-term archive of up to a month for most data sets
- 24x7 operational monitoring by NCEP staff
- a geographically-diverse backup server to insure operational
availability
A near-real-time server supported by NCDC is available at http://nomads.ncdc.noaa.gov/. This server provides
- access to a subset of NCEP's operational data set (as distributed on
NOAAPort) shortly after distribution
- a long-term archive for all data sets
- many other data sets (see
http://nomads.ncdc.noaa.gov/data.php?name=inventory)
Four non-operational research and development servers used for customer
testing of new products and services prior to operational implementation
- These servers are not guaranteed to have current data
- These servers are not guaranteed to be available at all times
- These servers and their content are supported only during
business hours
and on the basis of staff availability
- 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
A non-operational research and development server managed by NCDC is
