Subject: Soliciting Public Comments through April 19,
2013,
on the
Removal of NCEP’s Legacy Climate Diagnostic
Center Products.
The National
Centers for Environmental Prediction (NCEP) is
proposing to stop producing the legacy Climate
Diagnostic Center
(CDC)
ensemble-based precipitation and surface temperature grids
and disseminating them via the NCEP server.
These products are
not disseminated via NOAAPORT. NWS is seeking
comments on this
proposed change through April 19, 2013.
NCEP runs a
system developed by the CDC that uses an early global
atmospheric version of the Climate Data Analysis System
(CDAS)
with a resolution of T62 and 28 model
layers. This is followed
by a 15 member (control with 7 pairs) ensemble
forecast, run at
the 00Z cycle only. Forecasts for precipitation
and 995mb
temperature out to 360 hours are posted on the NCEP
server at:
http://www.ftp.ncep.noaa.gov/data/nccf/com/cdc/prod/
or
ftp://ftp.ncep.noaa.gov/pub/data/nccf/com/cdc/prod/
These products
have become obsolete and have been replaced by
the current operational output from the CDAS and
Global Ensemble
Forecast System
(GEFS). More details about the products available
from these systems is available at:
http://www.nco.ncep.noaa.gov/pmb/products/
NWS will evaluate
all comments to determine whether to proceed
with this change. If approved, NWS will issue a
Technical
Implementation
Notice giving 30 days notice of the
implementation date.
