Which system will always be considered automated, even when a weather technician augments or backs up an observation?

• A. Automated Stations
• B. AMOS
• C. ASOS
• D. AWOS

Answer: (A)

Automation in weather observations means the sensors and data systems operate on their own, producing readings without requiring a human observer. If a weather technician augments or backs up a reading, the underlying system is still automated—the human action is supplemental, not the method by which data are collected. That makes Automated Stations the best answer because it designates the system itself as automatic, regardless of any occasional human involvement. The other options describe specific automated observing systems that can still rely on human augmentation or backup in certain situations, so they aren’t guaranteed to be classified as automated in every scenario.
