The NOAA Weather Wire Service (NWWS) is a satellite data collection and 

dissemination system operated by the National Weather Service (NWS). ItŮs purpose is to provide state and federal government, commercial users, and private

citizens with timely delivery of meteorological, hydrological, climatological, and

geophysical information (a complete listing of NWWS products is available at

http://www.nws.noaa.gov/nwws/) . 

NWWS data products originate at 143 NWS offices, including 122 Weather Forecast Offices (WFO), 13 WFO/River Forecast Centers ((WFO/RFC), representing 26

NWS offices in 13 co-located facilities), and 8 NWS National Centers, utilizing the

Advanced Weather Information Processing System (AWIPS). NWWS also receives

products from the U. S. Geological SurveyŮs Earthquake Center. NWWS delivers 

priority 1 weather warning products to users within 10 seconds or less, making it

the fastest delivery method available for these critical products.

NWWS network administration, maintenance, and field support is provided by

Computer Science Corporation (CSC), under NWS contract.

Collection of products and satellite uplink is performed at all 13 WFO/RFCs, 5

National Centers, and 1 WFO. Products are then received from the satellite at

Master Ground Station # 1 in Woodbine, MD, delivered to the CSC Master

Processing Center (MPC) in Chantilly, VA., and broadcast back to the satellite to

users from Woodbine, MD. Most products are sent

twice through two satellite uplink sites (paired AWIPS hubs) to ensure receipt

if one site goes down. Additionally, NWWS receives back-up support from the

AWIPS Network Control Facility in Silver Spring, MD, for priority 1 weather

watches and warnings. Duplicate products are removed from the NWWS data

stream at MPC before broadcast.
