METARs
Provides access to decoded METAR (Meteorological Aerodrome Report) aviation weather observations. METARs are routine weather observations from airport weather stations, updated approximately every hour. METAR data is also used by the E6B endpoints to automatically calculate crosswind and density altitude for airports.
Standardized hourly aviation weather reports covering wind, visibility, clouds, temperature, dewpoint, and altimeter setting. Issued for airports; SPECI reports issued for significant changes between regular observations.
