Marine Forecast Offices and Centers provide links to their products as well as additional regionally focused information.

The National Weather Service's Family of Services (FOS) is made-up of multiple data streams of meteorological and hydrological messages. FOS serves mass media (newspapers, radio stations, TV, etc.) emergency management agencies and private weather services. It is not suitable for mobile platforms such as ships.

FOS is accessible via dedicated telecommunications access lines in the Washington, D.C., area. All FOS data services are driven by the NWS Telecommunication Gateway computer systems located at NWS headquarters in Silver Spring, MD.

Users may obtain any of the individual services from NWS for a on-time connection charge and an annual user fee. Several private companies subscribe to the FOS and then resell the data as received and/or provide value-added information services for their customers.

The FOS includes the following services:

Domestic Data Service (DDS)
Primarily comprised of bulletins containing United States weather information or observations.

International Data Service (IDS)
Primarily comprised of bulletins containing weather information or observations from outside of the United States.

Public Product Service (PPS)
Primarily comprised of bulletins containing information of urgent need, such as weather warnings and time critical information, such as hurricane and storm warnings.

High Resolution Data Service (HDS)
Primarily comprised of bulletins containing centrally generated analysis and forecast fields in binary code forms. This is a highly cyclical transmission stream for two to three hours after model run time containing products which requires computer decoding and display.

Digital Facsimile Service (DIFAX)
About 300 facsimile charts are disseminated every day. These include analyses, prognoses, and observed data, plus international aviation charts and agricultural products. This service will be discontinued on April 30, 2001, however, charts transmitted via DIFAX are planned to continue to also be made available via the Internet at: http://weather.noaa.gov/fax/graph.shtml

RADAR Products Service (RPS) The Radar Products Service (RPS) will provide direct user access to WSR-88D products in real-time. All radar products that the NWS is centrally collecting will be available on the RPS. The RPS is currently being tested, but is not yet operational. You can obtain additional information about RPS from the Radar Product Central Collection/Distribution Service web site.

Server Access Service (SAS)
Provides access to the NWSTG networks and resources that reside there, in particular the File Server.
