Abstract
A study has been made of the effect of wavelength on the attenuation of brightness contrast by the atmosphere. The results of the study have been expressed in terms of the variation in meteorological range with wavelength and indicate a linear relation between meteorological range and wavelength rather than a fourth power law, which might be expected on the basis of Rayleigh scattering. This linear relation has been found to hold for black objects and white objects for a wide range of transparencies of the atmosphere. From this result, it is concluded that even on the clearest of days there is in the atmosphere always an abundance of scattering nuclei of a size greater than molecular dimensions.
