What does ASOS stand for?

ASOS stands for Automated Surface Observing System, which is a key system used in aviation weather observing. It provides real-time meteorological data through automated sensors located at various locations, typically at airports. The system collects information on important weather parameters, including temperature, wind speed and direction, visibility, cloud cover, and precipitation. This data is crucial for pilots and air traffic controllers in making informed decisions about flight operations and safety.

The design of ASOS aims to enhance the efficiency of weather reporting, eliminating the need for continuous human observation while still ensuring accurate and timely data dissemination. Its automated nature allows for the collection of weather observations even in remote or challenging environments, thereby improving overall operational safety in aviation.
