Subject: Changes to the NWS Production Suite
1. NCEP FTP services changing 19 April 2006 - NCEP will be moving the location of
its operational data sets to a faster server located next to our connection to the
Internet at NOAA headquarters in Silver Spring, Maryland. This will provide users
with faster access to the operational data sets contained within the following
locations:
ftp://ftpprd.ncep.noaa.gov/pub/data
ftp://ftpprd.ncep.noaa.gov/pub/data1
ftp://ftpprd.ncep.noaa.gov/pub/data2
To accomplish this, the non-operational, NCEP center specific ftp content must be
separated from the ftpprd.ncep.noaa.gov interface. Users who still access these
data sets will need to now use the center specific ftp sites. For example, users
who access content from EMC at ftp://ftpprd.ncep.noaa.gov/pub/emc need to begin
accessing these data from ftp://ftp.emc.ncep.noaa.gov/. ; Access to the
non-operational data sets (NCEP center specific) via the ftpprd.ncep.noaa.gov
interface will be disabled on 19 April 2006. Further information on this change is
located at:
http://www.nco.ncep.noaa.gov/pmb/changes
2. The replacement of the NAM-Eta with the NAM-WRF is tentatively scheduled for
Tuesday, 13 June. Parallel data sets for the new NAM/WRF are available at:
ftp://ftpprd.ncep.noaa.gov/pub/data/nccf/com/nam/para/
3. An upgrade to the Global Ensemble Forecast System (GEFS) is tentatively
scheduled for Tuesday, 30 May. Parallel data sets for the new GEFS are available
at:
ftp://ftpprd.ncep.noaa.gov/pub/data/nccf/com/gens/para/
4. As soon as the moratorium on changes at the NWS Telecommunications Operations
Center (TOC) is lifted, NCEP will begin the transition from GRIB1 to GRIB2, by
placing duplicate GRIB2 files on the TOC FTP server. Both sets of data will remain
on the TOC FTP server for a minimum of 180 days to allow users to transition to the
GRIB2 data sets. More information will be provided once the TOC moratorium has
ended.
