Rationality of Characteristic for Optical State of the Atmosphere
A great many of the proposed characteristics for determining the optical state of the atmosphere have little suitability for recognizing in time the approach of a synoptic air mass [1–3]. Kh. Myurk, in attempting to find the best, most practically suitable characteristic, proposed the use of a rationality factor r. The main criteria of rationality are high sensitivity to atmospheric transmittance and little dependence upon the height of the sun. Then r is determined by the formula
where II is the transmittance characteristic, and the derivatives ∂Π/∂S and ∂Π/am determine its dependence upon the density of solar radiation flux and atmospheric mass (height of the sun).
