We present an analysis of variations in the total ozone content (TOC); the analysis is based on monitoring data from OMI-based observations. The analysis is confined to the territory of Russian Federation, within which the TOC variations are considered, in both latitude and longitude, with the consideration of specific features of TOC measurements poleward of the polar circle. For certain observation sites we calculated and presented autocorrelation functions, which, like standard deviation (variance), give an idea on TOC variations or TOC nonuniformities.
We present the time series of the total ozone content (TOC) over Tomsk, obtained using three independent spectrophotometers, and carry out their comparative analysis. Comparison of measurements by these instruments shows that they well correlate in terms of the pronounced variations, arising in time behaviors; but the amplitudes of the bursts differ. On the whole, we can note that the TOC values, obtained using IAO instrument, exceed those from two other instruments, TOC values from NASA instrument being the lowest. These smallest TOC values are especially apparent for the summer and fall periods.
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 period of 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., time. These functional relationships constitute the parametric equation of circle on the plane. This allowed us to conclude that the variations of these atmospheric constituents are formed mainly in two perpendicular directions.
We presented the time series of the total ozone (TO) content and integrated aerosol backscattering coefficient in the stratosphere, obtained at the Siberian Lidar Station in Tomsk. They are analyzed with the purpose of identifying, in their spectra, of inertial turbulence scale, at which the energy of variations, from large toward small scales, should decay according to the -5/3 law, with associated inner and outer turbulence scales. For TO time series it was found that the linear section is fit by straight line with the slope of -1.23, rather than -1.67 as it would in obedience to the Kolmogorov- Obukhov law. It is hypothesized that photochemical reactions of ozone formation serve as an additional energy source in inertial interval.
