Abstract : The extent of the changes in atmospheric transparency were studied analytically to determine its effect on the optical stability of the atmosphere, given by a stability criterion. A progressive method of measuring the optical properties of the atmosphere is proposed, and a coefficient n is defined as the degree of atmospheric instability. A set of 80 observations was selected over a period of 50 days, 60 of which showed n not exceeding 0.03. It was found that n could vary in a given day (during the observation series) with different filters. This was attributed to the change in aerosol quantity in the atmosphere as well as the aerosol spectra. All data were limited to clear atmospheric conditions with high transparency.
