What does the "AWOS" system stand for in aviation weather?

The term "AWOS" stands for Automated Weather Observing System. This system is crucial in aviation as it provides real-time weather data to pilots and meteorologists. The information gathered through AWOS includes temperature, wind speed and direction, visibility, and atmospheric pressure, which are essential for flight operations and safety.

The automated aspect of AWOS means that the system operates without the need for constant human monitoring, allowing for frequent updates and ensuring that the information presented is timely and accurate. This system is typically installed at airports and serves as a vital component for flight planning and decision-making, particularly in assessing conditions for takeoffs and landings.

The other options do not accurately reflect the established terminology used in aviation weather reporting. For example, while some terms might sound plausible, they either do not exist as recognized systems or misrepresent the purpose and operational nature of the AWOS.
