When sky conditions are described as "OVC007," what does the "007" indicate?

The description "OVC007" in atmospheric conditions refers specifically to overcast sky conditions. The "007" indicates that the cloud cover begins at 700 feet above ground level (AGL). This notation is part of aviation weather reporting standards, where the first two digits represent the height of the cloud base in hundreds of feet above the ground. Thus, "007" translates to 700 feet AGL.

Understanding this is crucial for pilots and drone operators as it provides vital information for safe flight operations, particularly regarding vertical visibility and potential cloud obstructions. The significance of altitude measurements in aviation weather is paramount, impacting everything from approach and landing strategies to general navigational decisions.
