Subject:  Amended:  Upgrade of the NCEP Air Quality Forecast
          System Effective December 14, 2010


Amended to change the date of implementation of changes from
December 21, 2010, to December 14, 2010.  Implementation of the
changes to the Air Quality Forecast System is sooner than
specified by NWS Policy (NWS Instruction 10-1805). The reduction
of the normal advance lead time was approved to ensure the
product will become available before the extended computer
system moratorium. Minimal changes to software will be necessary
to accommodate this product change.

Effective Tuesday, December 14, 2010 at 1200 coordinated
Universal Time (UTC), the National Centers for Environmental
Prediction (NCEP) will upgrade the Ozone Model run in its
operational production suite. This upgrade will provide the
following changes to this system:

 - Expand the operational ozone prediction products to add
   maximum 1 hour average and maximum 8 hour average ozone
   for the first day of prediction for CONUS

Once operational, the output from this enhanced processing will
be available from the NWS National Digital Guidance Database
(NDGD) server at:

ftp://tgftp.nws.noaa.gov/SL.us008001/ST.opnl/DF.gr2/DC.ndgd/GT.a
q/AR.conus/

Maximum 1 hour average and maximum 8 hour average ozone for the
first day of prediction for CONUS are currently generated twice
per day at NCEP.  These data can be obtained from the
experimental NDGD server at:

ftp://tgftp.nws.noaa.gov/SL.us008001/ST.expr/DF.gr2/DC.ndgd/GT.a
q/AR.conus/
