Abstract
We analyze the annual variations in the total ozone content (TOC) over Tomsk in period of 1994-2017 and integrated aerosol backscattering coefficient (IABC) in the period 2000-2016 obtained using M-124 ozonometer and lidar method, respectively. The correlation coefficient between these time series turned out to be -0.23, indicating that, although localized in the same altitude range, these time series are uncorrelated. Study of annual behaviors formed from these time series showed that TOC can be fitted by the function sin, while IABC, by the function cos. At the same time, both functions depend on a single parameter, i.e., the time in decades. This allowed us to conclude that the variations of these atmospheric constituents are formed mainly in two perpendicular directions. It is found that the annual behaviors of TOC and IABC consist of two sections, fitted by exponential curves.
