SUBJECT:  Amended Date: Upgrade of the NCEP Air Quality  

          Forecast System Postponed Until Sept. 21, 2010

 

Amended to postpone effective date for implementation of the upgrade of the NCEP Air Quality Forecast System from September 14, 2010, to September 21, 2010.

 

Effective Tuesday, September 21, at 1200 coordinated

Universal Time, 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 domain to add

  Hawaii and Alaska

 

Once operational, the output from this enhanced processing

will be available from the NWS National Digital Guidance

Database (NDGD) server:

 

Alaska : ftp://tgftp.nws.noaa.gov/SL.us008001/ST.opnl/DF.gr2/DC.ndgd/GT.aq/AR.alaska/

 

Hawaii : ftp://tgftp.nws.noaa.gov/SL.us008001/ST.opnl/DF.gr2/DC.ndgd/GT.aq/AR.hawaii/

 

Output from the new ozone model system is currently being

generated twice daily at NCEP. These data can be obtained from the experimental NDGD server:

 

Alaska : ftp://tgftp.nws.noaa.gov/SL.us008001/ST.expr/DF.gr2/DC.ndgd/GT.aq/AR.alaska/

 

Hawaii :

ftp://tgftp.nws.noaa.gov/SL.us008001/ST.expr/DF.gr2/DC.ndgd/GT.aq/AR.hawaii/
