Hemispherical Distribution of Turbidty Coeffieient as Estimated from Direct Solar Radiation Measurements

[摘要] A method of evaluating the atmospheric turbidity coefficient from direct solar radiation measurements without using filters and from simultaneous radio sonde observations is formulated, and the relation between the turbidity coefficient and Linke's turbidity factor is discussed. By application of the present method to the IGY data, the distribution of the turbidity coeffcient in the northern hemisphere and its seasonal variation are estimated. The effect of water vapor in the atmosphere and of rain or snow on the turbidity coefficient are discussed.
