name: NOAA — National Oceanic and Atmospheric Administration
description: 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.

    description: The National Weather Service public REST API delivers real-time weather forecasts, alerts,
      observations, gridded forecast data, aviation weather products, and metadata for offices, zones, and
      radar stations across the United States and US territories. Responses default to GeoJSON with content
      negotiation for JSON-LD, CAP, ATOM, and DWML. No API key is required — only a unique User-Agent string
      identifying the calling application. Stable production endpoint at api.weather.gov, current spec version
      3.9.2.
