USE AND EVALUATION OF BIOLOGICAL SPECTRAL UV WEIGHTING FUNCTIONS FOR THE OZONE REDUCTION ISSUE - Environmental UV Radiation: Impact on Ecosystems and Human Health and Predictive Models - page 70

Figure 2. (a) Solar spectral irradiance predicted by a model for temperate-latitude conditions in summer; (b, c)
two UV action spectra used as BSWF for sensitivity analysis: The Cen and Björn spectrum for enhancement
of ultraweak luminescence in leaves of Brassica napus [7], the Setlow composite spectrum for DNA damage
[8]. Spectra have been normalized at 300 nm and are shown plotted against log (b) and linear (c) axes.
