Final answer:
The main differences between AWOS-3 and ASOS lies in their capabilities and level of automation.
Step-by-step explanation:
The main differences between AWOS-3 (Automated Weather Observing System) and ASOS (Automated Surface Observing System) lie in their capabilities and the level of automation.
AWOS-3 provides weather observations for aviation purposes and is typically found in smaller airports. It offers basic information such as temperature, wind speed, and altimeter setting.
ASOS, on the other hand, is a system used for weather reporting and is typically found in larger airports. It provides more detailed weather information including visibility, cloud height, precipitation, and thunderstorm activity.
