METARs

Weather stations from around the world report weather conditions every hour using a data format referred to as METAR, a contraction of MÉTéorologique Aviation Régulièrea (believed to originate from the French phrase message d’observation météorologique pour l’aviation régulière). These data are centrally collected and distributed by the U.S. NWS (and other countries' equivalent weather organizations).

A METAR weather report is predominantly used by pilots in fulfillment of a part of a pre-flight weather briefing, and by meteorologists, who use aggregated METAR information to assist in weather forecasting.

Raw METAR is the most popular format in the world for the transmission of weather data. It is highly standardized through ICAO, which allows it to be understood throughout most of the world.
