Subject: Soliciting Public Comments through April 19, 2013,
on the Removal of NCEPs 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These products have become obsolete and have been replaced by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.
