Aviation Weather Center

The NOAA/NWS Aviation Weather Center (AWC) public data API provides machine-to-machine access to operational aviation weather products including METARs, TAFs, pilot reports (PIREPs/AIREPs), SIGMETs (domestic and international), G-AIRMETs and AIRMETs, Center Weather Advisories (CWAs), TFM convective forecasts (TCFs), area forecasts, area forecast discussions, meteorological information statements (MIS), and reference data for stations, airports, NAVAIDs, fixes, features, and obstacles. Responses are available in raw text, JSON, GeoJSON, XML, and (for METAR/TAF) IWXXM formats.

Aviation Weather Center publishes 2 APIs on the APIs.io network: Navigational Data API and Weather Data API. Tagged areas include Aviation, Weather, Government, NOAA, and NWS.

The Aviation Weather Center catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.

Aviation Weather Center’s developer surface includes documentation, code examples, and 16 more developer resources.
