Biological Responses to UV-B Radiation Dosagesther decay of the stratospheric ozone layer would not significantly contribute to an increase of the UV-protective reactions. This UV increase rather could inhibit these processes that depend on gene activation and, therefore, are sensitive to DNA damage, for example, by dimer formation.

The Effect of Clouds on Ultraviolet Radiationements with spatial variations showing a cloud edge enhancement effect are shown. This cloud edge enhancement effect can be explained by Mie scattering. It is proposed that jet contrails can actually increase the UV-B exposure levels near large airports.

Expected Changes in Irradiances, Particularly UV-B, in the Biosphere in stratospheric ozone have a high degree of uncertainty associated with them. Present chemical models predict the decrease of a few percent over the next decade. Resultant trends in UV will be difficult to detect with present and currently proposed monitoring efforts. Changes in UV levels, however

Surprisingly little is known about the biological effects of UV-B (290–320nm) radiation, the major region of the solar spectrum to be affected by ozone loss. This is partly because the UV-C spectrum, which DNA a
