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 22 API contracts indexed on the APIs.io network, including Alerts API, Aviation API, Glossary API, and 19 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 41 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Government & Public Sector regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/noaa-gov: open an issue to ask a question, or submit a pull request to add artifacts.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
