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:
