How is the height of layers recorded in MF1M-10C?

The height of layers in MF1M-10C is recorded in feet above the surface. This measurement is crucial for understanding weather conditions such as cloud cover and visibility, as it provides pilots and meteorologists with the necessary data to assess airspace safety and flight planning. When weather observations are made, reporting the height of cloud layers or other significant weather phenomena as a distance above the ground level allows for clearer communication of how high these elements are, which can significantly impact aviation operations.

Recording heights in feet above the surface aligns with aviation standards prevalent in the United States, making it easier for pilots to interpret the data relative to their altitude during flight. This standardization helps ensure a uniform understanding across different regions and among various aviation and meteorological entities.
