NOAA — National Oceanic and Atmospheric Administration
The National Oceanic and Atmospheric Administration (NOAA) is the United States scientific and regulatory agency within the Department of Commerce charged with monitoring oceanic and atmospheric conditions, charting the seas, conducting deep-sea exploration, managing fishing and protection of marine mammals, and providing weather, climate, space weather, and ecosystem forecasts and warnings. NOAA's developer surface spans six line offices — the National Weather Service (NWS), the National Environmental Satellite, Data, and Information Service (NESDIS) including the National Centers for Environmental Information (NCEI), the National Ocean Service (NOS) including Tides & Currents (CO-OPS), the National Marine Fisheries Service (NMFS / NOAA Fisheries), the Office of Oceanic and Atmospheric Research (OAR), and the Office of Marine and Aviation Operations (OMAO). NOAA exposes free, open APIs at api.weather.gov, services.swpc.noaa.gov, api.tidesandcurrents.noaa.gov, ncei.noaa.gov/access, ERDDAP servers across line offices, the National Data Buoy Center (NDBC), and bulk forecast model output (GFS, GEFS, HRRR, GOES) through the NOAA Open Data Dissemination (NODD) program on AWS, GCP, and Azure.
NOAA — National Oceanic and Atmospheric Administration publishes 13 APIs on the APIs.io network, including Alerts API, Aviation API, Glossary API, and 10 more. Tagged areas include Weather, Climate, Ocean, Space Weather, and Government.
The NOAA — National Oceanic and Atmospheric Administration catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.
NOAA — National Oceanic and Atmospheric Administration’s developer surface includes authentication, developer portal, documentation, engineering blog, support, and 36 more developer resources.
