Paper Abstract

Using satellite (Earth Probe TOMS) measurements of erythemal ultraviolet radiation (EUVR) we examine the global and regional (for Russia) spatial distributions of EUVR. Global distributions of monthly and yearly EUVR doses reveal continental "structures" and large mountain-masses. An examination of the EUVR distribution for the Russia's territory reveals meso-scale inhomogeneities of EUVR fields depending on the region and season under consideration. Our results are in qualitative agreement with earlier findings derived by other authors from investigating global distributions of the total ozone content that is a crucial agency for the supply of EUVR to the ground. We discuss the competing contribution from meteorological (cloud cover, aerosols) and other factors of influence of EUVR in the effects observed. Generally EUVR fields are produced under the influence of many atmospheric factors whose distribution can be affected by orographic conditions, the degree of continentality, circulation processes, and by the physico-geographic properties of the region.
