GFS DNG for Guam Headers
NCEP Home > NCO Home > Production Management Branch > GFS DNG for Guam Headers

  Page Updated:  08/13/2010

Effective Date: November 16, 2010

On the above effective date, the following Global Forecast System (GFS) downscaled numerical weather prediction (NWP) grids (DNG) of sensible hydromet elements for Guam will be disseminated over the Satellite Broadcast Network (SBN) and NOAAPort.

The following headers will be added to the SBN/NOAAPort:
