  • aviation_find_stations Resolve 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, whic
  • aviation_get_metar Get current weather observations (METARs) for named airports, or survey every reporting station inside a geographic area. Returns decoded fields — wind direction/speed/gusts, visibility, ceiling with its kind (measured, or indefinite for vertical visibility into an obscuration), present weather, tem
  • aviation_get_taf Get 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 th
  • aviation_get_pireps Get 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 r
  • aviation_get_advisories Get active domestic SIGMETs for a region. Returns each advisory with hazard type (CONVECTIVE, TURBULENCE, ICING, IFR), severity, altitude range, valid period, polygon coordinates, and raw text. Coverage is US-centric (NWS Aviation Weather Center). This tool reads the domestic SIGMET feed only and ca
