What does the acronym METAR represent?

The acronym METAR stands for Meteorological Aerodrome Report. This term is widely used in aviation and meteorology to refer to a standardized format for reporting current weather conditions at an airport or aerodrome. METAR reports typically provide vital information that includes temperature, dew point, wind speed and direction, visibility, significant weather phenomena, and cloud cover.

Understanding the significance of METARs is crucial for pilots and air traffic controllers as they rely on these reports to make informed decisions about flight operations, safety, and weather hazards. The format and content are regulated by the World Meteorological Organization (WMO) to ensure consistency and reliability across different regions.

In contrast, the other options relate to different contexts, none of which align with established meteorological reporting systems. For example, the other terms either focus on non-standardized reports or pertain to entirely different fields, such as military assessments or marine temperature analyses, which do not fit the aviation context of METAR.
