METAR reports are issued by national meteorological and aviation authorities and distributed by the U.S. National Oceanic and Atmospheric Administration via aviationweather.gov (NOAA/NWS Aviation Weather Center). As works of the U.S. federal government they are in the public domain.
Airport names, ICAO identifiers, and runway headings come from OurAirports, whose data is dedicated to the public domain. Each puzzle links back to the matching OurAirports page.
