What does METAR stand for?

The term METAR stands for Meteorological Aerodrome Report. This acronym specifically refers to a standardized format for reporting current weather conditions at an airport or aerodrome. It encompasses information crucial for aviation operations, including temperature, visibility, wind direction and speed, cloud cover, and any significant weather conditions.

Understanding METAR is essential for pilots and air traffic controllers as it provides timely data that contributes to decision-making processes related to flight safety and operational efficiency. The focus on aerodrome reporting differentiates it from other meteorological reports that may not pertain directly to aviation or airport environments, which is why options referring to reports like "Marine Environmental" or "Monthly Environmental" do not align with the correct definition.
