What does the acronym METAR stand for?

The acronym METAR stands for Meteorological Aerodrome Report. This type of report is a standardized format for reporting weather information at an airport. It provides essential data, including temperature, dew point, wind direction and speed, visibility, and significant weather phenomena. METAR reports are generated and disseminated at regular intervals, usually every hour, and serve as critical information for pilots and air traffic controllers to ensure safety and effective flight operations.

While other options may include elements of aviation or weather reporting, they do not represent the correct terminology associated with the METAR system used in aviation. The correct choice highlights the focus on meteorological data specifically related to aerodromes, making it fundamental for understanding current weather conditions that could impact flight operations.
