What function does the ASOS system serve?

The Automated Surface Observing System (ASOS) plays a critical role in providing real-time weather information to pilots, air traffic controllers, and meteorologists. This system automatically collects, processes, and disseminates weather data, including temperature, humidity, wind speed and direction, visibility, and precipitation. The primary function of ASOS is to enhance safety and operational efficiency in aviation by supplying accurate and timely weather reports that are essential for flight planning and in-flight decision-making.

Since ASOS is an automated system, it reduces human error associated with traditional weather reporting methods, ensuring consistency in data quality and availability. This accuracy is particularly important for drone operators and pilots who must assess weather conditions before and during flights to comply with safety regulations and maintain operational safety. Other options provided do not accurately describe the established function of ASOS, which specifically focuses on surface weather observation essential for aviation operations.
