Proceedings PaperMeasuring slant visual range on airports using an eye-safe lidar

The standard meteorological instrumentation of an airport includes visibility meters enabling the tower personnel to report the ground visibility conditions to an approaching pilot. In case of ground fog the slant visibility conditions for that pilot might be much better. This is the reason for introducing a ground based lidar system that is able to determine the slant visual range. Results of a measuring campaign at Hamburg Airport show a good correlation between ground and slant visibility for a homogeneous atmosphere and a significant distinction between the two values for ground fog situations.
