Abstract
This chapter investigates the extent to which trends of ultraviolet (UV) radiation can be derived by measurements. UV radiation is a rapidly changing quantity that depends on latitude, longitude, height, incident angle, azimuth angle, wavelength and polarization parameters. The irradiance is an integrated quantity only, but it has been measured reliably at several stations since the beginning of the 1990s.Most of the existing UV irradiance data sets in the northern hemisphere show an upward trend but we show that the time series are still too short to derive meaningful trends in most cases. The reasons are the high natural variability and the high autocorrelation of UV data. At Thessaloniki there has been an upward trend caused by a decrease in aerosol content at this site. If the current predictions about further ozone changes are correct, climate-related changes in clouds, aerosols and ground albedo will dominate the expected UV changes. Future research in UV should focus on the effects of clouds and aerosols and on the characterization of the spatial distribution of UV radiation (i.e., spectral radiance) which is needed to assess UV effects in medicine, biology or air quality.
