This study describes a relatively simple method to calculate solar diffuse and total irradiances for using in environmental photobiology estimations instead of complex atmospheric radiative transfer computer programs. The model reproduced calculations for equinoxes and solstices at 35° latitude made by a computer-intensive and rather complex atmospheric radiative transfer program (MODTRAN) with a mean error <6%. The overall accuracy obtained by the regression model presented is usable in most radiative transfer scenarios found in the atmosphere. The approach and equations presented in this study should assist in estimating the maximum time during which microbial pathogens remain infectious after accidental or intentional aerosolization in open environments.
