Abstract
Several researchers have pointed out that a realistic risk assessment of damages induced by UV-B radiation in organisms, especially in plants, can only be obtained if the experiments are performed under natural light and radiation conditions. This applies particularly to the balance between the UV-B, UV-A, and the visible or photosynthetic active component of solar radiation. The natural global radiation varies during the day and year both by intensity and spectral composition, which has to be taken into account for a realistic simulation of the solar radiation.

This contribution describes solar simulators at the GSF Research Center using state-of-the-art techniques for lighting and spectral shaping methods to obtain realistic and reproducible UV scenarios. The integrated irradiances reach values close to outdoor levels measured at our field station in Neuherberg near Munich, Germany. The spectral measurements demonstrate that our artificial sunlight provides a very close approximation of natural solar radiation in the range from 280 to 850 nm especially at the steep UV-B cut-off at the shortwave edge. The use of UV filters allows us to simulate the impact of increased UV radiation on various organisms and their acclimatisation to these conditions.
