How is cloud coverage height measured?

Cloud coverage height is primarily measured in feet above ground level (AGL). This standard measurement provides pilots and meteorologists with a clear understanding of how high cloud bases are relative to the terrain below. Using feet AGL is a convention established in aviation and meteorology, ensuring consistent communication and reporting among pilots, weather observers, and air traffic control.

The use of feet AGL is particularly important in aviation for flight safety and operations, as pilots need to be aware of cloud heights relative to their altitude. This measurement helps in determining cloud ceilings, which can inform decisions during takeoff, landing, and flying through various airspaces.

While other units like meters AGL or kilometers AGL are used in other contexts, feet AGL is the recognized standard in the aviation field, making it the correct answer for measuring cloud coverage height. The choice of yards AGL is less common and not utilized in meteorological reporting, further reinforcing why feet AGL is the appropriate measurement.
