RECONSTRUCTION OF CHANGES IN STRATOSPHERIC OZONE IN THE TAIGA FORESTS BASED OF THE SINGULAR SPECTRAL ANALYSIS
The relevance. The problem of reducing the level of stratospheric ozone and the interest in its past changes are associated with the increase in the dose of ultraviolet radiation in the short-wave range reaching the Earth's surface. Reconstruction and prediction of long-period fluctuations of t...

Reconstruction of historical changes in atmospheric characteristics can be considered in the context of the prospect of artificial restoration of forest resources. The aim of the research is to discuss a technique for reconstructing the total ozone content based on a multicomponent singular spectral model of the response of conifers annual growth rings.
