Retrieving Paleobehavior of the Ozone Layer from Dendrochronological Data Using Toms Satellite Data

The results of a correlation analysis of chronologies of the mean arithmetical values of minimum and maximum tree ring density and the mean total ozone content (TOC) values during the growing season, measured using the TOMS satellite, are given. A significant correlation was obtained that made it possible to retrieve ozone layer behavior for about five centuries in the past. The retrieved multicentury TOC series in different geographical regions is characterized by well-expressed long-period variations. The present-day state of the ozonosphere indicates a general dropoff in the content of stratospheric ozone at a global scale, although the amplitude of the dropoff for the time being does not exceed the maximum amplitudes of long-period variations in the past.
