Abstract:

Institute of Atmospheric Optics has developed a method of reconstruction of total ozone (TO) from dendrochronological data, which makes it possible to trace the TO behavior for a few centuries back to thousand years. In treatment of biospheric effect of the UV-B radiation at the wavelengths shorter than 310 nm, the data of TO measurements can be considered adequate and more efficient replacement of data of radiation measurements. In this paper we present some results the sensitivity of wood plants to long-term enhancement of UV-B radiation, search for significant bioindicators of stratospheric ozone in annual rings of coniferous trees, and also consider the possibilities of accounting for the effect of UV-B radiation and tropospheric ozone in the existing models of growth and structure of annual rings.
