Study of main components of long-period variations of stratospheric ozone according to reconstructed and instrumental data by caterpillar method

摘要

The paper presents the results of analysis of data of spatiotemporal variations of ozonosphere using modified Caterpillar method of main components (Saint Petersburg University). We use as the studied sample the TOMS satellite data of total ozone (TO) and data of TO reconstruction from annual ring density of coniferous trees for midlatitudes. We explored the possibility of approximation of TO time series based on simple components separated by this method.
