          Diagnostic Center Products: Effective July 2013

Effective no later than Tuesday, July 16, 2013, the
National Centers for Environmental Prediction (NCEP) will
stop producing legacy Climate Diagnostic Center (CDC)
ensemble-based precipitation and surface temperature grids
and disseminating them via the NCEP server. These products
are not available via NOAAPORT.

A Public Information Statement was issued on March 4, 2013
requesting comments on the proposed termination of these
products.

http://www.weather.gov/os/notification/pns13cdc_removal.htm

Based on responses received, NWS will terminate the CDC
products no later than July 16, 2013.  The removal date may
occur earlier if the NWS transition to the new
supercomputing system happens prior to July 16.  A revised
TIN will be issued to announce the revised termination date
if necessary.

The CDC products use 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 users should use
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:
