aviation_find_stationsread-onlyResolve an airport or weather reporting station by its identifier, or discover stations within a bounding box or US state. Returns all identifier variants (ICAO/IATA/FAA), coordinates, elevation, and available data types (METAR, TAF, SYNOP, etc.). A lookup matches the registry's own identifier, which for an airport is its 4-character ICAO ID (e.g., KSEA, KJFK, K0S9); buoys and mesonet sites carry
aviation_get_metarread-onlyGet current weather observations (METARs) for named airports, or survey every reporting station inside a geographic area. Returns decoded fields â wind direction/speed/gusts, visibility, ceiling with its kind (measured, or indefinite for vertical visibility into an obscuration), present weather, temperature, dewpoint, altimeter, cloud layers â plus the computed flight category (VFR/MVFR/IFR/LI
aviation_get_tafread-onlyGet the Terminal Aerodrome Forecast (TAF) for one or more airports. Returns each forecast period with valid times, surface wind, low-level wind shear, visibility, decoded weather conditions, cloud layers, and the vertical visibility into a forecast obscuration, plus the raw TAF string. TAFs cover the next 24â30 hours and are issued only for airports with scheduled commercial service; check data_
aviation_get_pirepsread-onlyGet recent Pilot Reports (PIREPs) near an airport or within a bounding box. Returns decoded turbulence, icing, and cloud reports with altitude, aircraft type, intensity, outside air temperature, wind aloft, flight weather, and the raw PIREP string. Requires either station_id (ICAO center point for radial search, e.g., KSEA) or bbox (area search) â not both. distance_nm belongs to the station_id
aviation_get_advisoriesread-onlyGet active domestic SIGMETs, international SIGMETs (including oceanic products), and Center Weather Advisories from the NWS Aviation Weather Center. Filter by advisory_type, hazard, or ordered bbox. Returns source coverage, decoded hazards/altitudes/movement, multipart geometry, and original bulletins; missing facts stay null. Independent source failures retain healthy results with partial coverag
