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 72

Figure 3. The relationship between ozone reduction and UV-B calculated with the two BSWF of Figure 2.
(a) Cen and Björn [7]; (b) Setlow [8]. These represent relative total integrated daily biologically effective UV-
B on the summer solstice at 40° latitude. Also shown are the relative daily integrated UV-B values for current
ozone conditions at different latitudes at the time of year of maximum solar irradiation. From [10].
