ASOS stands for which system?

Explanation:
ASOS is the Automated Surface Observing System, a standardized, automated weather observation system at airports. It continuously gathers surface weather data with sensors and processors, including wind direction and speed, visibility, present weather, sky condition (cloud cover and height), temperature, dew point, and altimeter pressure. This data is used to generate METARs and to support flight planning and safety by providing timely, consistent surface weather information. The other names don’t reflect the official system used for aviation weather observations, so ASOS is the correct designation.
