Research subject for a potential FP6 project

Analysis of two extensive collections of UBV photoelectric measurements of atmospheric extinction (from years 1962 – 1995) obtained at two different sites (Skalnate Pleso and Brno Observatories) revealed seasonal and long-term variations. As photoelectric measurements can distinguish between two components of the extinction, (one of them is caused by Rayleigh scattering on air molecules, the second one by the scatter of light on dust particles), we came to the conclusion, that the variable component of extinction is caused by dust in the Earth\'s atmosphere. The current rate of the relative growth of dust extinction is appr. 11 % per year. As Skalnate Pleso is a mountain observatory (1783 m above sea level), we can use these measurements as a pollution indicator in Central Europe. Some predictions of the pollution can be done. New extinction data were obtained since 1995 at Skalnate Pleso and Stara Lesna Observatories.Comparison with similar data covering different geographical sites at different elevation in Europe are highly needful.
