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. deliveryModel: model: saas license_evidence: not_product: - noaa-emc/global-workflow - noaa-gsl/rocoto - weather-gov/api - weather-gov/weather.gov open_source: unknown commercial: true callable_host: true label: Hosted service · you call their endpoint confidence: low source: - openapi - pricing - repository-not-product generated: '2026-09-25' method: derived accessModel: pricing: unknown onboarding: unknown trial: false try_now: false public: false label: Unknown confidence: low source: - authentication - security generated: '2026-09-03' method: derived image: https://www.noaa.gov/themes/custom/noaa_components/logo.svg created: '2026-05-25' modified: '2026-05-25' specificationVersion: '0.23' tags: - Weather - Climate - Ocean - Space Weather - Government - Open Data - Forecast - Marine - Atmospheric - Hydrology - Satellite - Fisheries - Aviation - Emergency Management - Alerts - Tides - Aviation Weather - Environmental - Government Data - Atmosphere - Federal Government apis: - aid: noaa-gov:swpc-data-service name: Space Weather Prediction Center (SWPC) Data Service description: >- SWPC publishes solar wind, geomagnetic, X-ray flux, aurora forecast, radiation storm, and coronal mass ejection products through a static-file data service organised by format.
