Introduction.--Langley's method for the management of solar radiation data is to plot the logarithm of a measured radiation intensity, as ordinate, against the secant of the zenith distance of the sun, asabscissa. Beer's law (Eq. I) forms the physical basis for this procedure. Langley's method is justified for measurements in the visible and ultraviolet spectral regions because Rayleigh scattering, particle scattering and ozone obsorption predominate as attenuating agencies in the atmosphere there.
The transmission of the atmosphere is, according to Beer's law :
7" = IO -(a'+a2+''') .... (I)
