authorized.” NOAA services NOAA works toward its mission through six major line offices, the National Environmental Satellite, Data and Information Service (NESDIS), the National Marine Fisheries Service (NMFS), the National Ocean Service (NOS), the National Weather Service (NWS), the Office of Oceanic and Atmospheric Research (OAR) and the Office of Marine & Aviation Operations (OMAO). and in addition more than a dozen staff offices, including the Office of the Federal Coordinator for Meteorology, the NOAA Central Library, the Office of Program Planning and Integration (PPI). National Weather Service The National Weather Service (NWS) is tasked with providing "weather, hydrologic and climate 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." This is done through a collection of national and regional centers, 13 river forecast centers (RFCs), and more than 120 local weather forecast offices (WFOs). They are charged with issuing weather and river forecasts, advisories, watches, and warnings on a daily basis. They issue more than 734,000 weather and 850,000 river forecasts, and more than 45,000 severe weather warnings annually. NOAA data is also relevant to the issues of climate change and ozone depletion. The NWS operates NEXRAD, a nationwide network of Doppler weather radars which can detect precipitation and their velocities. Many of their products are broadcast on NOAA Weather Radio, a network of radio transmitters that broadcasts weather forecasts, severe weather statements, watches and warnings 24 hours a day. National Ocean Service The National Ocean Service (NOS) focuses on ensuring that ocean and coastal areas are safe, healthy, and productive. NOS scientists, natural resource managers, and specialists serve America by ensuring safe and efficient marine transportation, promoting innovative solutions to protect coastal communities, and conserving marine and coastal places. The National Ocean Service is composed of eight program offices: the Center for Operational Oceanographic Products and Services, the Office for Coastal Management, the National Centers for Coastal Ocean Science, the Office of Coast Survey, the Office of National Geodetic Survey, the Office of National Marine Sanctuaries the Office of Ocean and Coastal Resource Management and the Office of Response and Restoration. There are two NOS programs, namely the Mussel Watch Contaminant Monitoring Program and the NOAA Integrated Ocean Observing System (IOOS) and two staff offices, the International Program Office and the Management and Budget Office.
