Abstract
New physical inputs are summarized and placed in analytic forms suitable for calculations of the ultraviolet spectral irradiance reaching the ground. These include (a) recent values of the extraterrestrial solar spectral irradiance based upon the work of Heath et al.; (b) improved analytic characterizations of ozone attenuation coefficients; (c) an improved equation for the Rayleigh optical depth based upon the work of Frohlich and Shaw; and (d) a detailed characterization of aerosol extinction coefficients for various wavelengths and relative humidities based upon the recent work of Shettle and Fenn. In addition, we refine the ratio method of Green, Cross and Smith for characterizing the diffuse spectral irradiance to provide a better interpolation formula between the numerical output of the models of Dave, Braslau and Halpern. Applications of the work are described.
