Ultraviolet Radiation and Aquatic Microbial Ecosystems,inter and spring and about 4% in summer and fall as compared with the values of 1970. For the Southern Hemisphere midlatitudes, an erythemally weighted increase in surface solar UV of about 6% has been determined on a year-round basis (Madronich et al. 1998).

Because of difficulties in extrapolating from indoor studies to field situations, I focus on recent findings from field studies, with particular reference to those employing ambient UV-B filter exclusions and modulated UV-B supplements.

Ultraviolet Radiation and Exobiology,Earth. Planets around other stars will also have very different surface UV regimens, determined partly by their atmospheric composition but also by the fact that the spectral quality of light emitted by other stars can be very different from that of our own Sun.
