Abstract:

This report presents measurements of atmospheric volume scattering coefficients collected during twenty-nine low altitude flights made during the Winter and Summer seasons of 1978 at four different European locations. The measurements were conducted during an instrumented aircrafts final approach and landing at its staging airbase. The measurements were made using a pseudo-photopic spectral response and thus are suitable for comparison with data associated with standard visual determinations of airfield visibility. The data illustrate that in twenty-six of twenty-nine cases, there was little or no significant variation in the value of scattering coefficient as the aircraft approached the surface from an altitude of several hundred meters.
