How is a layer height of 7,500 feet reported in an observation?

In aviation weather reporting, a layer height is typically reported using a specific format where the thousands and hundreds of feet are excluded. Therefore, a layer height of 7,500 feet would be reported as '075'. This format makes it easier for pilots and meteorologists to quickly interpret the height of the weather layers without confusion.

The number '075' signifies 7,500 feet because it keeps the reporting within a two or three-digit format, with the assumption that if a leading zero exists, it refers to a height in the thousands. Hence, the understanding is that when '075' is seen in observations, it translates to 7,500 feet.

Other options present numbers in a way that does not align with standard reporting practices. For instance, simply writing '7500' would imply a different context and does not follow the correct protocol for transmitting layer height. The reported format requiring the removal of the thousands place is a crucial aspect of clear communication in aviation meteorology.
