NWS Office of Dissemination
 

The National Weather Service (NWS) provides weather, hydrologic,
and climate, observations, forecasts, and warnings for the United States, its territories, adjacent waters and ocean areas, for the protection of life and property and the enhancement of the national economy. Our
mission is to provide timely, efficient, and reliable weather, water, and climate information to improve public safety for a Weather-Ready Nation.

The Office of Dissemination, specifically the Dissemination Systems Branch (DSB), conceives, designs, implements, and manages telecommunications systems required to distribute meteorological and hydrologic data, reports, information, and weather warnings to the public, public safety agencies, and the mass news media through governmental and public telecommunications systems.

DISSEMINATION SYSTEMS


NOAA Weather Radio All Hazards (NWR)  - seven (7) discrete FM
frequencies for broadcasting local weather, alerts, and hazard warnings. Some receivers can connect to external alerting devices.

 

NOAA Weather Wire Service (NWWS)  - fastest method of receiving
text weather information, alerts and warnings over either the Internet
or a 1.8m C-Band satellite dish.  For highest product availability, use both.

 

Emergency Managers Weather Information Network (EMWIN) -
NWS text, satellite imagery and graphic products over the Internet
and via high data rate over the Geostationary Operational Environmental Satellite (GOES) network
using 1.0m C-band satellite dish.

International Services and Communication Systems (ISCS) -
a collective group of message dissemination systems used to
provide weather, water and climate information to segments of the World Meteorological Organization (WMO) International community;
includes 

  • GeoNetCast - Americas (GNC-A)  - provide weather and water warnings and information in various formats via C-Band broadcast.

  • GTS Internet File Service (GIFS)   - alternate method of receiving GNC-A weather and water information over the public Internet.

  • EMWIN is included here because it also services the international community
