The “Boundary Layer Height” product provides hourly forecasts for the next seven days, indicating the height of the atmospheric boundary layer in kilometers. This variable is crucial for aviation, especially for small aircraft and glider flights, as the boundary layer height affects turbulence, atmospheric stability, and flight conditions. Higher values indicate a larger mixed air column, providing better flying conditions, while lower values may signal turbulence and limitations on safe flight altitude. The forecast helps with planning and ensuring the safety of aerial operations.
