Paper Abstract

A brief review of the psychophysical relationships which influence an observer's ability to discern barely perceptible changes in apparent contrast is presented with comments related to meteorological observations and instrument calibrations. Examples of how uncertainties in the specification of the atmospheric optical state might influence slant path contrast transmittances are illustrated.
