Examining the quasibiennial oscillation of total ozone and ozone concentrations at separate stratospheric levels according to data of TOMS satellite instrumentation

摘要

The pattern of the quasibiennial oscillation of total ozone over northern territories of Russia (1996-2013) and ozone concentrations at separate stratospheric levels over Arctic sites (2005-2013) are analyzed according to data of TOMS satellite instrumentation. It is shown that the entire period of 1996-2013 can be divided into three intervals: before 2002-2004, interval between 2002-2004 and 2008-2010, and period after 2008-2010. The quasibiennial oscillation is quite clearly manifested in the first and third periods and is distorted in the second period. The time series of the mixing ratio, composed for separate altitudinal levels, exhibit quasibiennial oscillation, which takes shape at heights of ～30 km and weakens in overlying regions.
