The acronym translates from French as Aviation Routine Weather Report
MET eorological viation eport. An evaluation of selected weather elements from a site on or near the ground according to a set of procedures. It may include type of report, station identifier, date and time of report, a report modifier, wind, visibility, runway visual range, weather and obstructions to vision, sky condition, temperature and dew point, altimeter setting and remarks. METARS are normally issued either hourly or half hourly, but if there is a significant change in conditions at the site, a SPECI (special report) may be issued. See also SYNOP.
Coded aerodrome Met report.
Opinions vary as to what this stands for – some say Meteorological Terminal Air Report. It's an hourly or half-hourly report from the meteorological office of an airport, giving details of current weather conditions, including temperature, dew point, wind speed and direction, cloud base and coverage, and QNH.
Meteorological Airfield Report.
a weather code used at airports
Met eorological viation Routine Weather eport, provided every half hour and consists of half-hourly observations at the airport, contains weather parameters like wind, visibility, weather, clouds, temperature, dewpoint and mean sea level pressure.
An acronym derived from the French, and basically meaning "aerodrome weather". This weather observation coding format is the primary format for weather data distribution in North America, though it is used at many airports in other regions. The format is relatively readable and is designed mostly for the aviation sector. METAR observations are usually taken every hour, although larger airports may produce a report every 30 minutes. Special reports can also be sent when conditions have changed significantly since the last report was sent. (Part of this definition is from "Weather Forecasting Handbook", 5th ed., Tim Vasquez).
Acroymn for METeorological Aerodrome Report. It is the primary observation code used in the United States to satisfy requirements for reporting surface meteorological data. Minimum reporting requirments includes wind, visibility, runway visual range, present weather, sky condition, temperature, dew point, and altimeter setting.
Aviation Routine Weather Report (coded)
Meteorological Aviation Report
1. Abbreviation for Meteorological Terminal Air Report; also known as Aviation Routine Weather Reports. 2. The international standard code for hourly and special observations that took effect on 1 July 1996.
Acronym for MET eorological erodrome eport. It is the primary observation code used in the United States to satisfy requirements for reporting surface meteorological data. Minimum reporting requirements includes wind, visibility, runway visual range, present weather, sky condition, temperature, dew point, and altimeter setting.
METAR is a format for reporting weather information. METAR means "aviation routine weather report" and is predominantly used by pilots in fullfilment of a part of a pre-flight weather briefing.
