Abstract:
The UV radiation plays an essential role in many processes in the biosphere, including the influence on the human body, and may be very harmful if UV exposure exceeds certain limits. The main results achieved in Action 726 are published in the Final Report and in the e-Atlas, which contains the elaborated UV maps for Europe for about 50 years and a sample of long-term spectral UV data. The knowledge of the ozone and UV changes has expanded considerably since the “ozone hole” discovery in the early 1980s and the subsequent establishment of the Ozone Convention in 1985, and the Montreal Protocol in 1987. The awareness of the potential ozone depletion threat and the resulting increase in the UV radiation reaching the Earth surface stimulated the world-wide multidisciplinary research on UV radiation transfer in the atmosphere and its potential influence on the Earth’s ecosystems. The correlation between the ozone and UV changes and the climate changes has been recognised. The COST Action 726 “Long term changes and climatology of UV radiation over Europe” was established in 2004. Its main objective is to advance the understanding of the UV radiation distribution under various meteorological conditions, in order to determine the UV radiation climatology, and to assess the long-term UV changes over Europe, starting in the 1950s. The main objectives of this booklet are to show the importance of the scientific results of Action 726 for the European community, to increase the awareness of the potential threat of UV radiation to human health, and to urge people to use appropriate protective measures. This booklet initially provides basic information on solar UV radiation reaching the Earth surface (section 2.1). Sections 2.2 and 2.3 describe the measurements of UV and the methods of retrieving the UV by modelling and reconstruction. The main results of the Action, i.e. the geographical distribution and temporal variability of UV radiation in Europe, are presented in section 2.4. Chapter 3 describes the biologically effective UV radiation and its influence on the human body, animals, micro organisms, plants and the aquatic biosphere. Chapter 4 presents the current expectations on future UV changes. Appendixes A, B, C show the European dimension of the COST Action 726 and contain useful web addresses and references. This booklet is addressed to the broad European community to help further the understanding of the UV radiation impact on the Earth surface, with its potential positive and harmful influences, and to stress the necessity of using protective measures. In particular, we address this booklet to journalists and school teachers.
